It looks like you might not have defined a <code>start</code> script in your <code>package.json</code> file or your project does not contain a <code>server.js</code> file.

<blockquote>
 If there is a server.js file in the root of your package, then npm will default the start command to node server.js.
</blockquote>

<a href="https://docs.npmjs.com/misc/scripts#default-values">https://docs.npmjs.com/misc/scripts#default-values</a>

You could either change the name of your application script to <code>server.js</code> or add the following to your <code>package.json</code>

<pre><code>"scripts": {
 "start": "node your-script.js"
}
</code></pre>

Or ... you could just run <code>node your-script.js</code> directly

If you are using babelify and watchify, go to:

and add this in "scripts":

 "start": "watchify the-path-to-your-source-jsx-file -v -t [ babelify --presets [ react ] ] -o the-path-to-your-output-js-file"

An example would be:

<pre><code>"scripts": {
 "start": "watchify src/main.jsx -v -t [ babelify --presets [ react ] ] -o public/js/main.js"
}
</code></pre>

should avoid using unstable npm version.

I observed one thing that is npm version based issue, npm version 4.6.1 is the stable one but 5.x is unstable because package.json will be configured perfectly while creating with default template if it's a stable version and so we manually don't need to add that scripts.

I got the below issue on the npm 5 so I downgraded to npm 4.6.1 then its worked for me,

<hr>

ERROR: npm 5 is not supported yet

<hr>

It looks like you're using npm 5 which was recently released.

Create React Native App doesn't work with npm 5 yet, unfortunately. We
recommend using npm 4 or yarn until some bugs are resolved.

You might have an old (global) installation of npm which causes the issue. As of 12/19, npm does not support global installations.

First, uninstall the package using: 
<code>npm uninstall -g create-react-app</code>

Some osx/Linux users may need to also remove the old npm using: 
<code>rm -rf /usr/local/bin/create-react-app</code>

This is now the only supported method for generating a project: 
<code>npx create-react-app my-app</code>

Finally you can run: 
<code>npm start</code>

I am getting this error with a ruby on rails app, I don't know what script name to put in my package.json file. I tried:
<pre><code>&quot;scripts&quot;: {
 &quot;start&quot;: &quot;webpack-dev-server --hot&quot;
 }
</code></pre>
But I got this error:
<pre><code>remote: App container failed to start!!

I am not very familiar with these sorts of problems so am a bit lost!

entityMap|blocks|key|1acl8|text|我得到这个错误是因为我没有在终端的正确目录中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5foud|带有脚本的应用程序在B文件夹中。B文件夹在A文件夹中。我在vscode中打开A文件夹，在内置终端中输入"npm+run+start“，得到错误信息。尝试"cd文件夹B"，在ide中打开文件夹B，或者比我一开始更好地组织你的东西。^0|0^^$0|$]|1|@$2|3|4|5|6|7|8|E|9|@]|A|@]|B|$]]|$2|C|4|D|6|7|8|F|9|@]|A|@]|B|$]]]]

I got this error because I wasn't in the right directory in terminal.
App with the scripts was in folder B. Folder B was in folder A. I open folder A in vscode and enter &quot;npm run start&quot; into the built in terminal and got the error. try &quot;cd folder B&quot;, opening folder B in the ide, or organizing your stuff better than I did in the first place.

I just stumbled upon this issue. I reinstalled NPM, created a new React app (so basically a clean install) and still no luck.
Finally figured it out:
My terminal was NOT in the correct location.
I had to changedirectory one level deeper into my app.
So my terminal was in my 'projects' folder instead of my 'my-app' folder
Path: '/Documents/projects/my-app'
