Create-react-app: "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!

[gaearon]

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.

[KarandikarMihir]

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

[gaearon]

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

[gaearon]

I can't reproduce this on a Windows laptop. Tried both Cmd and PowerShell, both npm and yarn.
Can anybody who reproduces this think more about what makes your setup special?

[phoa]

@gaearon - my setup is as follow:

• using standalone NodeJS Windows 64 Binary 6.10.2 and NPM 4.6.1 from NPM Github Release Page
• yarn is installed via npm install -g yarn
• i'm behind corporate-proxy, so my NPM and Yarn have proxy and https-proxy config setup
• there are corporate-specific scripts running behind the scene, which may or may not contribute to the error

A colleague of mine has the same setup, and he also got the same error message.

Up till now, the ejected version is still running fine without problem for me, despite the error message during eject.

[tchojnacki]

Same, works fine despite the message.
@gaearon

• Windows 8.1
• Node v7.5.0 and NPM 4.1.2
• yarn installed using .msi
• firewall disabled completely

Can't find anything special about my setup apart from that.

[K4bl0-Skat3R]

same prob... any solution ... I dont running yarn together :(

[lu-xuelei]

New to react-native and facing the same problem. Any update to this in the last one year?

PS: > node -v
v8.10.0
PS: > npm -v
6.0.1

[kingdiamond666]

I just had the same problem...same err messages, same debug log. If you are using Git make sure you do a commit before running eject, it worked for me!
