I encountered the same issue. After searching and reading different things online, what worked for me was:

    $ brew postinstall node

However, first please do execute:

    $ brew doctor

and follow the instructions there first, like the comment in your question mentions.

Try running

    $ brew postinstall node

Try the following:

`$ brew update`&lt;br&gt;
`$ brew uninstall node`&lt;br&gt;
`$ brew install node`&lt;br&gt;
`$ sudo chown -R YouComputerName /usr/local/lib/node_modules/`&lt;br&gt;
`$ brew postinstall node`

the same problem with you, I fixed by:

`/usr/local/lib/node_modules/npm/bin/npm-cli.js i -g npm`

I used cyrillic (non-latin) characters in my hostname/computername on mac. And that was the problem. After i changed this and reinstalled node/npm with Homebrew everything worked like normal. No utf8 in 2017? :/

running: `echo &#39;export PATH=&quot;/opt/homebrew/opt/node@16/bin:$PATH&quot;&#39; &gt;&gt; ~/.zshrc` should work, change node@16 to just node or which ever version you just installed.

I created a completely new, single-view iOS universal Swift app. Then, I unchecked &quot;Landscape Left&quot; and &quot;Landscape Right&quot; in the app settings. I ran it on my iPhone, and hooray, it stays in portrait mode no matter how I rotate my phone. Then I ran it on my iPad, and it rotates to anything. Even upside-down portrait mode, which wasn&#39;t enabled in the first place? Am I the only experiencing this? This happens in the iPad simulator as well when I rotate with command+arrow key. 

I also tried adding the following to ViewController.swift, and got the same result.
    
    override func shouldAutorotate() -&gt; Bool {
        return false
    }
    
    override func supportedInterfaceOrientations() -&gt; UIInterfaceOrientationMask {
        return UIInterfaceOrientationMask.Portrait
    }

Is there no way to actually disable rotating away from portrait on iPad?

How do I disable landscape-orientation on an iPad app?

I have a simple Angular 2 component with `@Input`, which I bind to the template. The template shows input data, but I cannot access it from the constructor:

    import {Component, View, bootstrap, Input} from &#39;angular2/angular2&#39;;
    import DataService from &#39;./data-service&#39;;
    
    @Component({
        selector: &#39;app-cmp&#39;
    })
    @View({
    	template: `{{data.firstName}} {{data.lastName}}` //-&gt; shows the correct &#39;data&#39;
    })
    export default class NamesComponent {
      @Input() data: any;
      constructor(dataService: DataService) {
        console.log(this.data);//undefined
      }
    }

Here is a [plunker][1] with an example (see &quot;names-component.ts&quot;).

What am I doing wrong?

I&#39;ve installed node using `brew install node` and when I use the `node -v` I get following `v5.0.0`. However when I try to run the `npm` command I get `npm: command not found`. 

I&#39;ve tried to run `brew install npm`, however I just got following response `node-5.0.0 already installed`.

It happened with node also returning command not found, but that I fixed by running `brew link node`, however npm still does not seem to work.

How can I resolve this problem?

In https://stackoverflow.com/a/18658613/779159 is an example of how to calculate the md5 of a file using the built-in crypto library and streams.

    var fs = require(&#39;fs&#39;);
    var crypto = require(&#39;crypto&#39;);
    
    // the file you want to get the hash    
    var fd = fs.createReadStream(&#39;/some/file/name.txt&#39;);
    var hash = crypto.createHash(&#39;sha1&#39;);
    hash.setEncoding(&#39;hex&#39;);
    
    fd.on(&#39;end&#39;, function() {
        hash.end();
        console.log(hash.read()); // the desired sha1sum
    });
    
    // read all file and pipe it (write it) to the hash object
    fd.pipe(hash);

But is it possible to convert this to using ES8 async/await instead of using the callback as seen above, but while still keeping the efficiency of using streams?

In js file, i used import to instead of require

    import co from &#39;co&#39;;

And tried to run it directly by nodejs since it said import is &#39;shipping features&#39; and support without any runtime flag (https://nodejs.org/en/docs/es6/), but i got an error

    import co from &#39;co&#39;;
    ^^^^^^

    SyntaxError: Unexpected token import

Then i tried to use babel

    npm install -g babel-core
    npm install -g babel-cli
    npm install babel-core //install to babel locally, is it necessary?

and run by 

    babel-node js.js

still got same error, unexpected token import?

How could I get rid of it?

I am trying to get data from my mongoDB database by using mongoose filters. The scenario is that each user object in the database has certain fields like **&quot;Region&quot;** or **&quot;Sector&quot;**.

Currently I am getting all the users that contain the keyword **&quot;region&quot;** in there object like so:

     // Filter all healthcare bios by region
     app.get(&#39;/user&#39;,function(req, res) {

	 // use mongoose to get all users in the database
	 User.find({region: &quot;NA&quot;}, function(err, user) 
	 {
		// if there is an error retrieving, send the error. nothing after res.send(err) will execute
		if (err)
		{
			res.send(err);
		}
		// return all todos in JSON format
		console.log(user);
		res.json(user);
		
	});
    });

**How can put some conditions in mongoose that it return users that contain both &quot;region&quot; &amp;&amp; &quot;Sector&quot; in their objects.** Currently its only returning the user which have the region keyword in them. 

I have tried using $and operator but I couldn&#39;t get it to work.

How should I read and write a text file from typescript in node.js? 
I am not sure would read/write a file be sandboxed in node.js, if not, i believe there should be a way in accessing file system.

I have font-awesome in my node_modules folder so I try to import it in my main .scss file like so:

    @import &quot;../../node_modules/font-awesome/scss/font-awesome.scss&quot;;

But Webpack bundling compilation fails, telling me

    Error: Cannot resolve &#39;file&#39; or &#39;directory&#39; ../fonts/fontawesome-webfont.eot 

because the font-awesome.scss file refers to a relative path, &#39;../fonts/&#39;.

How can I tell scss \ webpack to @import another file, and use that file&#39;s folder as the home folder so that its relative paths work as it expects?

What&#39;s the simplest way to get an environment variable from a docker container *that has not been declared in the Dockerfile*?

For instance, an environment variable that has been set through some `docker exec container /bin/bash` session?

I can do `docker exec container env | grep ENV_VAR`, but I would prefer something that just returns the value.

I&#39;ve tried using `docker exec container echo &quot;$ENV_VAR&quot;`, but the substitution seems to happen outside of the container, so I don&#39;t get the env var from the container, but rather the env var from my own computer.

Thanks.

I am looking to pragmatically stop and delete a Docker container if it is running.  This is for a build script.

Take the following example.  How would I stop and delete the Docker container &quot;rabbitmq&quot; as seen under the NAMES column in a bash script?

    docker ps

    CONTAINER ID        IMAGE             COMMAND                  CREATED             STATUS              PORTS                   NAMES
    9909a5e2856f        rabbitmq-image   &quot;/docker-entrypoint.s&quot;   11 minutes ago      Up 11 minutes       0.0.0.0:5672-&gt;5672/tcp, rabbitmq
    8990dd1fe503        redis-image      &quot;/entrypoint.sh redis&quot;   6 weeks ago         Up 4 days           0.0.0.0:32770-&gt;6379/tcp redis
    etc 
The following command will delete the container and does what I&#39;m looking to do

    docker stop rabbitmq &amp;&amp; docker rm -f rabbitmq


However, it&#39;s combing it into a script that I would like to know? I think it would look something like this.  


    #!/bin/bash
    
    if [ /*docker ps check some value */ ]; then
       docker stop rabbitmq &amp;&amp; docker rm -f rabbitmq
    fi

I have this directory called &quot;mock&quot;, which contains 3 directories. I am trying to copy all the items from &quot;mock&quot; directory into the &quot;projweek&quot; directory using the following command:

    cp  /mock/* ~/projweek

But I get this error:

&gt; cp: cannot stat ‘mock/*’: No such file or directory

Any ideas as to why that is?

I&#39;d like to put together a command that will print out a string of 32 hexadecimal digits. I&#39;ve got a Python script that works:

    python -c &#39;import random ; print &quot;&quot;.join(map(lambda t: format(t, &quot;02X&quot;), [random.randrange(256) for x in range(16)]))&#39;

This generates output like:

    6EF6B30F9E557F948C402C89002C7C8A 

Which is what I need.

On a Mac, I can even do this:

    uuidgen | tr -d &#39;-&#39;

However, I don&#39;t have access to the more sophisticated scripting languages ruby and python, and I won&#39;t be on a Mac (so no uuidgen). I need to stick with more bash&#39;ish tools like sed, awk, /dev/random because I&#39;m on a limited platform. Is there a way to do this?

I&#39;m trying to set up less on phpstorm so I can compile .less files to .css on save. I have installed node.js and the next step (according to this [https://www.jetbrains.com/webstorm/help/transpiling-sass-less-and-scss-to-css.html][1]) is running this command in the terminal

I&#39;m developing a web app at work in React/Redux/Webpack and am now starting to integrate testing with Mocha.

I followed [the instructions for writing tests in the Redux documentation][1], but now I have run into an issue with my webpack aliases.

For example, take a look at the imports section of this test for one of my action creators:

    import expect       from &#39;expect&#39;                 // resolves without an issue
    import * as actions from &#39;actions/app&#39;;           // can&#39;t resolve this alias
    import * as types   from &#39;constants/actionTypes&#39;; // can&#39;t resolve this alias
    
    describe(&#39;Actions&#39;, () =&gt; {
      describe(&#39;app&#39;,() =&gt; {
        it(&#39;should create an action with a successful connection&#39;, () =&gt; {
    
          const host = &#39;***************&#39;,
                port = ****,
                db = &#39;******&#39;,
                user = &#39;*********&#39;,
                pass = &#39;******&#39;;
         
          const action = actions.createConnection(host, port, db, user, pass);
    
          const expectedAction = {
            type: types.CREATE_CONNECTION,
            status: &#39;success&#39;,
            payload: { host, port, database, username }
          };
    
          expect(action).toEqual(expectedAction);
        });
      });
    });

As the comments suggest, mocha isn&#39;t able to resolve my import statements when they are referencing aliased dependencies. 

Because I&#39;m still new to webpack, here&#39;s my `webpack.config.js`:

    module.exports = {
      devtool: &#39;eval-source-map&#39;,
      entry: [
        &#39;webpack-hot-middleware/client&#39;,
        &#39;./src/index&#39;
      ],
      output: {
        path: path.join(__dirname, &#39;dist&#39;),
        filename: &#39;bundle.js&#39;,
        publicPath: &#39;/static/&#39;
      },
      resolve: {
        extensions : [&#39;&#39;, &#39;.js&#39;, &#39;.jsx&#39;],
        alias: {
          actions: path.resolve(__dirname, &#39;src&#39;, &#39;actions&#39;),
          constants: path.resolve(__dirname, &#39;src&#39;, &#39;constants&#39;),
          /* more aliases */
        }
      },
      plugins: [
        new webpack.optimize.OccurenceOrderPlugin(),
        new webpack.HotModuleReplacementPlugin(),
        new webpack.NoErrorsPlugin()
      ],
      module: {
        loaders: [{
          test: /\.js$/,
          loaders: [&#39;babel&#39;],
          exclude: /node_modules/,
          include: __dirname
        }]
      }
    };

Also, I&#39;m using the command `npm test` to run mocha, here&#39;s the script I&#39;m using in my `package.json`.

     {   
       &quot;scripts&quot;: {
         &quot;test&quot;: &quot;mocha ./src/**/test/spec.js --compilers js:babel-core/register --recursive&quot;
       }
     }

So here&#39;s where I get stuck. **I need to include the aliases from webpack into mocha when it runs.**

I&#39;m not 100% sure, but I believe I installed node v5 from the windows installer on both my home and office PCs.

On my home PC global installs happen under %APPDATA%:

    (dev) go|c:\srv&gt; which lessc
    c:\users\bjorn\appdata\roaming\npm\lessc
    c:\users\bjorn\appdata\roaming\npm\lessc.cmd

while on my office PC, they go under program files:

    (dev) go|w:\srv&gt; which lessc
    c:\program files\nodejs\lessc
    c:\program files\nodejs\lessc.cmd

I need to provide the full path to a number of these global tools to PyCharm&#39;s file watcher, and since the project file i shared it would make sense to not have global resources under a user folder.

Why would the global installs end up in different folders, and how can I force them to a location that is common to all team members?

I need to clean install vscode on my mac. I opened the terminal and removed the `.vscode/` from `~`. I also delete the `Visual Studio Code.app/` from `/`. However, after deleting all that and download a fresh copy, I installed and open the editor and the editor remembered the last project I had. For me, that means that it is something else I need to delete but I can&#39;t find it. I went to the documentation but can&#39;t find anything about uninstalling the editor. Does anyone know how to completely uninstall VSCode from mac?

### What I have tried

Following this instructions and new installation of vscode keeps remembering the last project I opened.
