VSCode : doesn't detect changes

[pierre-H]

Is this a bug report?

Yes

Can you also reproduce the problem with npm 4.x?

Yes

Which terms did you search for in User Guide?

I tried https://github.com/facebookincubator/create-react-app/blob/master/packages/react-scripts/template/README.md#npm-start-doesnt-detect-changes

Environment

1. node -v: 8.4.0
2. npm -v: 5.3.0
3. yarn --version (if you use Yarn): 0.27.5
4. npm ls react-scripts (if you haven’t ejected):

Then, specify:

1. Operating system: Windows 7 32bits
2. Editor : vs code 1.15.1

Steps to Reproduce

1. Just created a new project with create-react-app
2. yarn start
3. edit a file (index.js for example)

Expected Behavior

When I edit and save a file with vs code, it should reload the server automatically.

Actual Behavior

Doesn't do anything : I have to restart yarn start.

But if I use another editor like Notepad++, it works perfectly

Odd; have you followed our Troubleshooting guide for this specific problem?

I don't believe VSCode has added "safe write", so I'm not sure what is unique about your environment.

[pierre-H]

@Timer yes I followed it and no result.

Unfortunately there's nothing we can do to help, this is a system problem as you said it works with other text editors.

Please file a bug with VSCode, who might then redirect you to Node.

For now, you can set CHOKIDAR_USEPOLLING=true and it should get you up and running. I wouldn't rely on this forever, though.

Good luck!

After investigation, yarn is the problem origin : wmonk/create-react-app-typescript#148
