I am experiencing the same problem.

[simonhaenisch]

It's probably because you have installed jest-cli@25 instead of jest-cli@24?

[starikcetin]

It's probably because you have installed jest-cli@25 instead of jest-cli@24?

"jest-cli": "24.9.0" is the entry in my package.json.

[simonhaenisch]

Hm ok it happens to me only when I upgrade jest, jest-cli and @types/jest to version 25. With 24.9 it seems to work fine.

[peterennis]

Confirmed. Jest 24.9 OK, Jest 25 fail.
I will update the ticket title.

The ticket opened on jest reports this solution:

This is due to how stencil import runCLI here: https://github.com/ionic-team/stencil/blob/45821831683d0a468b1e38a3179b4c03c2acba7a/src/testing/jest/jest-runner.ts#L31. This was changed in #8874 (comment)

They can change their import from const { runCLI } = require('jest-cli'); to const { runCLI } = require('@jest/core');. That package started shipping in 24.3.0, so it should probably be a fallback if runCLI is not found from jest-cli package to support all releases of Jest 24. Can also do const { runCLI } = require('jest'). The programmatic API is pretty bad, tracked in #5048

[driskull]

We are running into this issue as well.

[mmakrzem]

same issue for me

same issue for me

The related Jest issue.

If upgrade to Jest 25 then const { runCLI } = require('jest-cli'); has to be replaced with const { runCLI } = require('@jest/core');

[elpupi]

@peterennis is right. It would be nice if somebody could take care of it. Is it planned?
