[happyoliver]

🐛 Bug Report

Keep getting "Error: Cannot find module '@babel/traverse'" when running jest.

Original report : kulshekhar/ts-jest#2684

Have installed the required packages and separately installed. @babel/traverse which didn't help either.

Steps to reproduce the behavior:

}
}

Expected behavior

自分もnode v12.4.0で実行した場合同じ現象が発生しました。
nodeのバージョンをv14.17.1にアップデートした結果
問題は解決しました。

I had the same problem when running on node v12.4.0.
As a result of updating the node version to v14.17.1
The problem has been solved.

I have the same problem.

• npm@7.24.0
• jest 27.2.1

The package I installed is only jest (and its dependencies).

After down grading jest to 26.6.3, the problem was also resolved.

[BuggMaker]

same issue with node v12; switch node to v15 and reinstall node_module, problem solved

[SimenB]

Thanks for the reproduction @sdkawata, sorry I missed it!

Node version: v12.4.0
this problem does NOT occur in node v14.17.1 and v12.22.1

Minimum supported node version (of v12) is 12.13: https://github.com/facebook/jest/blob/42b020f2931ac04820521cc8037b7c430eb2fa2f/package.json#L148, so if the issue is only with 12.4 we can close this.

Can anyone provide a reproduction using a supported version of node?

---

Note that jest-snapshot does have a dependency on @babel/traverse, so this is more than likely a bug in your package manager than in Jest: https://github.com/facebook/jest/blob/42b020f2931ac04820521cc8037b7c430eb2fa2f/packages/jest-snapshot/package.json#L21

[sdkawata]

Thank you for the reply.

Minimum supported node version (of v12) is 12.13:

Sorry for not checking minimum supported version.

I checked my reproduction in node v12.13.0, v14.15.0, v15.0.0, and confirmed that the problem does not occur in node v12.13.0, v14.15.0, v15.0.0.

I dig into this error, and find that error throw from require.resolve function in requireOutside function defined here.
https://github.com/facebook/jest/blob/bc50e7f360ab1845abbaa0b3ad788caead0d3174/scripts/babel-plugin-jest-require-outside-vm.js#L27-L31
This is because require.resolve() fails to resolve path if options without path given in node v12.4.0.
This issue fixed in nodejs/node#28078.

Welcome to Node.js v12.5.0.
Type ".help" for more information.

So, I think we can close this issue because this problem may not occur in supported node version.

Great, thanks for digging into the root cause @sdkawata!
