Also, react-app-rewired directly fails when use command yarn start, due to the same issue described above.

Hey guys I find out this could be a bug which relates to yarnpkg itself.

It seems that yarn does not install babel-loader which couldn't be found in node_modules directory, however if the version of yarn is prior to 1.0.0 babel-loader would be installed properly.

[daresam]

A simple fix to that just install 'babel-loader' again by typing yarn add babel-loader on your terminal

[OshotOkill]

@daresam Yeah I manually install babel-loader as well, being my temporary solution. I've opened an issue on yarn and see if they can figure it out and handle it.

[gaearon]

Closing because the issue is with a package manager.

[seemystories]

I've just faced the exact same issue but I'm using npm as my package manager.
update: I installed yarn and I'm still having the issue there. Although It can be solved by installing 'babel-loader' manually

[velopert]

I am having the same issue.

[GustavoFenilli]

for people having this problem, just run yarn/npm install after ejecting and it should be fine, some dependencies after ejection seens to be missing.

I have faced same issue when I run the command> npm run eject, but I've solved this issue by run this command> yarn add babel-loader@7.

I installed babel-loader, but I keep getting the same issue? What else could be a problem?

@rades12340 try npm/yarn install !
