"yarn run eject" ejected succcessfully, but followed by "The batch file cannot be found."

[phoa]

Can you reproduce the problem with latest npm?

Yes.

Description

I started a fresh project with create-react-app. yarn start and yarn run build runs as expected. However, when running yarn run eject, it shows Ejected successfully!, but followed by

Ejected successfully!

Should I worry about this?
yarn start and yarn run build still run fine after eject tho.

Expected behavior

No error message after Ejected successfully!

Actual behavior

Got error message after Ejected successfully!

Environment

1. npm ls react-scripts (if you haven’t ejected): react-scripts@0.9.5

2. node -v: 6.10.2

3. npm -v: 4.5.0

4. Operating system: Windows 7 (behind corporate firewall)

This is very odd. I don't know what's causing this. 😞

[viankakrisna]

maybe related? http://stackoverflow.com/questions/26240414/jenkins-deleting-batch-file-before-its-completed it's jenkins but the symptoms pretty similar

@phoa do you able to consistently replicate this problem? eg. tried to create another CRA instance and eject it?

[phoa]

@viankakrisna It consistently happens when I eject (10 tries). Same thing happens when I tested it on my colleague's computer.
The ejected package runs fine tho. So far I do not see any problem with it.

I kinda suspect that this may be caused by some corporate settings applied to our computers.
This is not happening with my personal computer.

[jasenf]

I get the same error, running Windows 10. Exact same entries in my log file.

[ro-savage]

This is happening in windows CI for PR #2400

Looks like it might be to do with running the latest version of yarn (0.24.5) as thats the only change that the PR makes

[jazzfog]

Got this message too, Windows 10.

[cheryllium]

Got same error, Windows 8.

[mihir0x69]

Got same error on windows 10. FWIW, sharing the logs too.

Does anyone want to look into why this happens? I don't know enough about Windows.
