Just add `/` before `static/`, should be like

      /static/

    # ^ forward slash before the folder name signifies root dir

I am creating a form in Angular 2. My goal is to get data from the API and pass it into the form for editing purposes. However, I am running into this error:

&gt; EXCEPTION: Uncaught (in promise): Error: Error in ./EditPatientComponent class EditPatientComponent - inline template:1:10 caused by: formGroup expects a FormGroup instance. Please pass one in.


Here is the current code with the error.

**html**

    &lt;section class=&quot;CreatePatient&quot;&gt;
        &lt;form [formGroup]=&quot;patientForm&quot; (ngSubmit)=&quot;onSubmit()&quot;&gt;

I have a python animation script (using matplotlib&#39;s funcAnimation), which runs in Spyder but not in Jupyter.  I have tried following various suggestions such as adding &quot;%matplotlib inline&quot; and changing the matplotlib backend to &quot;Qt4agg&quot;, all without success.  I have also tried running several example animations (from Jupyter tutorials), none of which have worked.  Sometimes I get an error message and sometimes the plot appears, but does not animate.  Incidentally, I *have* gotten pyplot.plot() to work using &quot;%matplotlib inline&quot;.

Does anyone know of a working Jupyter notebook with a SIMPLE inline animation example that uses funcAnimation.  Thanks in advance for the help!

and I have installed git on the folder named `project` there is a folder named `static` and another folder called `app` and inside the `app` folder, there is another folder `static`. The above `.gitignore` ignore both static folders, That is not what I want.

What I want is to ignore the folder `project/static/` not the folder `project/app/static/` How can I do that?

Some time ago I added info(files) that must be private. Removing from the project is not problem, but I also need to remove it from `git` history.

I use Git and Github (private account).


Note: On [this thread][1]  something similar is shown, but here is an old file that was added to a feature branch, that branch merged to a development branch and finally merged to master, since this, a lot of changes was done. So it&#39;s not the same and what is needed is to change the history, and hide that files for privacy.

I&#39;m very new to GitHub/[VCS][1].

When I try to share my project on GitHub, I get the following error message.

        Can&#39;t finish GitHub sharing process

I&#39;ve googled the error message and got no hits. I&#39;ve also searched Stack&amp;nbsp;Exchange, but no cigar. How can I solve this issue?

Using Visual Studio Code (version 1.11.2), I can see a side-by-side graphical diff of my current changes very easily by clicking the *Source Control* button in the left panel. But once I commit those changes to my local repository, I am unable to find a way to see the same side-by-side diff from origin/master.

In other words, is there a way to the spawn comparison tool of Visual Studio Code (version 1.11.2) to show me what I see when I do `git diff origin/master`, but in the side-by-side graphical diff too?




Is there a way to see git diff from origin/master using Visual Studio Code?

When I do a `git pull`, from the git bash, the terminal usually runs the pull, updates my local, and then hangs. I&#39;m not sure if it&#39;s waiting for me to do something, but I usually exit out of this with `CTRL-C`. After that, I get that an index.lock is preventing me from doing other things to which I have to delete it. Am I misunderstanding how `git pull` works?

Why does git pull hang?

See the image below. My .gitignore file should be ignoring all files in src/dist, but isn&#39;t.

Why is .gitignore not ignoring my files?

To lock the versions of dependencies that are installed over a project, the command `npm install` creates a file called `package-lock.json`. This was made since [Node.js v8.0.0][1] and [npm v5.0.0][2], as several of you might know.

Despite of [Node.js][3] and [npm][4] recommendations about committing this file, several concerns regarding when you should avoid to do it, are also an option. Typically we commit in our projects, nevertheless, it is a peculiar question.

While we should commit the `package-lock.json` file by default, we have a specific case we should not. For instance, if we want to test the latest version of our project dependencies, it can be an option to add `package-lock.json` into `.gitignore`.

So, the questions are as follows:

 1. Should the `package-lock.json` file be added to `.gitignore`?
 2. Is there any particular situation that we **MUST** or **MUST NOT** do it?

I updated my Android Studio [from 3.0.1 to 3.1](https://developer.android.com/studio/releases/index.html), and noticed an unfamiliar file in my existing project:

    .idea/caches/build_file_checksums.ser

It doesn&#39;t depend on whether you update the Android Gradle plugin to [the latest 3.1.0](https://developer.android.com/studio/releases/gradle-plugin.html#3-1-0); once I opened an existing project in Android Studio 3.1, it automatically created the file `build_file_checksums.ser`, even if I kept the project to use the previous 3.0.1 plugin as follows.

    dependencies {
        classpath &#39;com.android.tools.build:gradle:3.0.1&#39;
    }

I also created a new project in Android Studio 3.1, and found that the file `build_file_checksums.ser` was created from the beginning.

At the time of writing, there seems to be no official documents on this. I would appreciate it if anyone could find it.
