I have tested this with beta 15 and beta 16.

Edit: nvm it seems you removed Babel from the project...
This could be a bug

Thank you.

I am pretty sure I not removed babel on purpose and that Babel was checked in the new project wizard. I tried again now, creating new project. Making sure Jest and babel was chosen, and the same error occurs.

I saved as a preset. Is there any way to export this preset?

[yyx990803]

Hmm, ok so my commit fixed the issue when Babel was not selected, but it seems you actually wanted Babel.

So it looks more like a problem of creating the project through UI is unintentionally dropping the Babel plugin. That looks like something similar to #1479. /cc @Akryum

I'm received a similar error on and off since -beta.14. I just got it with -rc.1. (below).

The workaround I found here works for me: jestjs/jest#3202 (comment) - delete jest* from your temp dir.

    ({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,global,jest){import "core-js/modules/es6
.promise";
