I have migrated my app to babel 7 beta and everything seems to work except the tests. I think I've read everything out there but I'm still getting this error:

● Test suite failed to run

Requires Babel "^7.0.0-0", but was loaded with "6.26.0". If you are sure you have a patible version of @babel/core, it is likely

that something in your build process is loading the wrong version. Inspect the stack trace of this error to look for the first entry that doesn't mention "@babel/core" or "babel-core" to see what is calling Babel.

You need to have both babel-core@^7 and @babel/core@^7 along with babel-jest@latest, try adding

yarn add babel-jest babel-core@^7.0.0-0

as mentioned in here https://github./facebook/jest/issues/5525

In my case, it turned out I had explicitly install this package by npm i -D babel-jest.
