[Bug]: Test environment resolves to wrong version when using `pnpm`
Version
30.2.0 and 24.9.0 inside a mono-repo
Steps to reproduce
git clone https://github.com/nicojs/jest-bug-pnpm-resolve
cd jest-bug-pnpm-resolve
pnpm install
cd test/jest-latest-version
node --run test
And see the error:
Expected behavior
PASS spec/math.spec.js
PASS spec/concat.spec.js
Test Suites: 2 passed, 2 total
Tests: 4 passed, 4 total
Actual behavior
Test environment found at "/Users/nicojs/repos/github/tmp/node_modules/.pnpm/[email protected]/node_modules/jest-environment-node/build/index.js" does not export a "getVmContext" method, which is mandatory from Jest 27. This method is a replacement for "runScript".
Additional context
The problem is with the current test environment resolve mechanism. It doesn't honor strict dependency resolve rules.
You can see it clearly by running jest --showConfig:
[...]
"testEnvironment": "/Users/nicojs/repos/github/tmp/node_modules/.pnpm/[email protected]/node_modules/jest-environment-node/build/index.js
[...]
Note that it resolved to v24.9.0 instead of 30.2.0

Found a workaround by installing jest-environment-node myself in the jest-latest-version package.
@nicojs can you help verifying my PR able to fix your issue with the following patch? I can confirm it works on my own account but would like to acquire your result as well.

Thanks for the quick response 🙏
This is strange. pnpm t now works, but node --run test doesn't. Is this also what you expected?

Ran all test suites.
I've pushed a new commit that handle node --run test in pnpm project, can you remove node_modules and rerun back to fetch newer packages?
Sorry for the delay.
I still get the same issue. I've removed my pnpm-lock.yml file and node_modules and run pnpm i. I've committed it to the repo so you can validate my work.
