Do you want to request a feature or report a bug?

What is the current behavior?

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem. Your bug will get fixed much faster if we can run your code and it doesn't have dependencies other than React. Paste the link to your JSFiddle (https://jsfiddle.net/Luktwrdm/) or CodeSandbox (https://codesandbox.io/s/new) example below:

What is the expected behavior?

Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?

this sounds like an issue for facebook/create-react-app instead

but, have you tried rm -rf node_modules && npm install?

[emjgreen]

I also have this problem, has anyone found a fix?

[edgesoft]

@suprim12 @emjgreen Make an issue at https://github.com/facebook/create-react-app as @hawkins suggest and you will certainly get help there.

npm probably had some kind of outage (or you might be behind a proxy). Try again.

I have this today - and tried both with npm and yarn... going to the CRA repo to open issue

This seems to have been a bug in [email protected] from what I can tell. Upgrading to react-scripts@^2.1.4 works just fine. 👍

Below is the npm ls babel-loader output showing no erroneous dependencies on babel-loader

Hi,

As our colleague above explained, the issue is when you have installed somehow the package outside of the project. Because of how node works, it checks for same package at the top level of hierarchy.
