Compatibility with Babel 7? #4748

Jest does not work with Babel 7 (at least with the env preset).

https://github.com/julien-f/jest-babel7

Is there anything I can do to work-around this?

Please use the issue template.

This issue happens because we use babel-core@6 within babel-runtime. Fixed in #4557. So if you install jest@test instead of jest@latest it works.

this doesn't work? jest@test installs jest-runtime@21.3.0-beta.15 which does not have this fix...

@jquense in the meantime we released jest@22

Related note: on top of installing jest@test (which currently translates to 21.3.0-beta.15), you may also want to do the same with babel-jest ((which also translates to 21.3.0-beta.15) to keep those in sync. In my case that fixed and issue around using --coverage which would throw a No file coverage available for {...} error.

@mistercrunch that's old! 23.6.0 is latest stable, and installing jest@beta will give you jest@24.0.0-alpha.9

I'm not sure in which specific hole of dependency hell I got caught into, but somehow managed to fall back on my feet while using the latest jest.
