well it turns out to be quite simple:

    &quot;scripts&quot;: {
      test_projectA:&quot;cd ../projectA &amp;&amp; npm run-script test&quot;
    }

You should use [`--prefix`][1].

```
npm run [command] --prefix path/to/your/other/folder
```

And for yarn:

```
yarn --cwd path/to/your/other/folder [command]
```

I ended up using:
```js
&quot;scripts&quot;: {
   &quot;job&quot;: &quot;cd ./sub &amp;&amp; \&quot;$npm_execpath\&quot; run subjob&quot;,
   ...
}
```

because this also works with __yarn__.

Is it possible to add text to a custom icon marker? I want to avoid having to edit the icon in an image editor just to add the text. 

I&#39;ve created my custom icon marker like so:

    var airfieldIcon = L.icon({
            iconUrl: &#39;images/airfield.png&#39;,
            iconSize: [48,48]
    });

    var airfield = L.geoJson (airfield, {
        pointToLayer: function(feature,latlng){
            return L.marker(latlng, {
                icon: airfieldIcon
            })
        }
    }).addTo(map);

How would I add the text &quot;Banff Airfield&quot; as a label to this icon? Is the easiest and most efficient way through using an image editor? if so, I will do that method, but wondering if there was a better way. Thanks!

I have a simple Firebase function that updates some data. However, the interpreter says that the first argument contains &quot;undefined&quot; in property &#39;users.tester1&#39;. Can somebody help me please?

    var objify = function() {
      var rv = {};
        for (var i = 0; i &lt; arguments.length; ++i)
          rv[arguments[i]] = rv[arguments[i+1]];
        return rv;
    }
        
        addUser(&quot;tester1&quot;, []);
    
    var addUser = function(name, edges){
      if(!checkIfUsernameExists(name) &amp;&amp; !checkIfNodeNameExists(name) &amp;&amp; !checkIfEdgeNameExists(name)){
        var time = Firebase.ServerValue.TIMESTAMP;

        //HERE: I think the error is on this line 
        refs.users.update(objify(name, &quot;filler&quot;));

        refs.users.child(name).set({
          &quot;id&quot; : time,
          &quot;edges&quot; : &quot;filler&quot;
        });
        refs.users.child(name).child(&quot;edges&quot;).update({
          &quot;to&quot; : &quot;filler&quot;,
          &quot;from&quot; : &quot;filler&quot;
        });
    
        addNode(new Node(name, time, name));
    
        for(var e in edges){
          refs.users.child(name).child(&quot;edges/to&quot;).update(objify(edges[e].name, true));
          addEdge(new Edge(edges[e].name, time, edges[e].to, edges[e].arrows));
          //TODO add a &quot;from&quot; edge so that you know who wants to eat you
        }

Firebase.update failed : first argument contains undefined in property

I have two separate projects that use npm - so I have both :  
`some_base_folder/projectA/package.json` and `some_base_folder/projectB/package.json`

Each of those files has a `scripts` section in it.  

If I go to `some_base_folder/projectA/` and run `npm run-script test` it executes the test command from the scripts section of `some_base_folder/projectA/package.json` as it should.

What can I put as the value of `&quot;scripts&quot;: {test_projectA:&#39;????&#39;` in `some_base_folder/projectB/package.json` so that when I am in `some_base_folder/projectB/` and I run `npm run-script test_projectA` it will be 
execute the `test` script of Project A?

I tried `../projectA/npm run-script test` but it says:

    &#39;..&#39; is not recognized as an internal or external command,
    operable program or batch file.

I am running under windows 7 but would prefer a solution that would also work properly on linux.


npm script command to run a script command from another package.json

I have two separate projects that use npm - so I have both :

I am trying to run another NodeJS version with `nvm` but getting this error:

    $ nvm use v4.2.4

    nvm is not compatible with the npm config &quot;prefix&quot; option: 
       currently set to &quot;/Users/z/.npm-global&quot;
    Run `npm config delete prefix` or `nvm use --delete-prefix v4.2.4` to unset it.

I have my prefix set on purpose to avoid `sudo npm` (see https://docs.npmjs.com/getting-started/fixing-npm-permissions).

Is there any way I can use `nvm` without losing my prefix for globally installed packages?

Is it possible to upgrade `node` right in place, instead of manually installing the latest stable version? 

I have installed [node.js][1] version `5.0` with [```nvm```][2], but now I want to update it to `5.4`. I&#39;m trying to avoid having to manually reinstall all of my global packages (*e.g.* by running `npm install -g grunt-cli bower yo yoman-angular-generator blabla blablablabla`...).

How to properly upgrade node using nvm

I was previously using gulp and running gulp to start my application and listeners from the [Visual Studio Code debugger](https://code.visualstudio.com/docs/editor/debugging) but have recently needed to switch to running scripts through *npm* instead. Unfortunately in VSCode I&#39;ve not been able to run *npm* scripts through the debugger so I&#39;ve had to resort to running *node* to start my server directly which gets rid of my listener tasks which reloaded code automatically. 

This seems like something that should be simple but so far I haven&#39;t had much luck. Below is a snippet from my launch.json file that I attempted to use but *npm* could not be located.

    {
        ...
			&quot;program&quot;: &quot;npm&quot;,
			&quot;args&quot;: [
                &quot;run&quot;,
                &quot;debug&quot;
            ],
        ...
    }

This gives me the following error.

&gt; Error request &#39;launch&#39;: program &#39;c:\myproject\npm&#39; does not exist

How to debug using npm run scripts from VSCode?

I want to try using npm to run my various build tasks for a web application.  I know I can do this by adding a `scripts` field to my `package.json` like so:

    &quot;scripts&quot;: {
       &quot;build&quot;: &quot;some build command&quot;
    },

This gets unwieldy when you have more complex commands with a bunch of options.  Is it possible to move these commands to a bash script or something along those lines?  Something like:

    &quot;scripts&quot;: {
       &quot;build&quot;: &quot;build.sh&quot;
    },

where `npm run build` would execute the commands in the `build.sh` file?

Reading through [this](http://substack.net/task_automation_with_npm_run) post it seems like it is, but I&#39;m not clear on exactly where I&#39;m supposed to drop my `build.sh` file or if I&#39;m missing something.

Running bash scripts with npm

I am stuck with this error no matter what directory I am in, and what I type after &quot;npm&quot; in cmd.exe. Here is the npm-debug.log:

I have tried and uninstalling/reinstalling nodejs multiple times, I even deleted npm and npm-cache folders in C:\Users\me\AppData\Roaming. I&#39;m not sure what went wrong to cause this. One second it was working fine, and now I can&#39;t get rid of this error. The explanation in the log does not make sense, as it gives this error in any directory. I should note that running a command prompt as administrator does not give this error. I&#39;m pulling my hair out this Friday evening trying to get this fixed, any help would be greatly appreciated!
