Yarn Modern Plug'n'Play (pnp) E2E fails with "Error: Cannot find module 'pnpapi'" #27562

MikeMcC399 · 2023-08-16T07:41:35Z

Current behavior

Attempting to run an E2E project based on a Yarn Modern Plug'n'Play (pnp) configuration using Cypress 12.17.4 fails with "Error: Cannot find module 'pnpapi'".

This is a regression from Cypress 12.17.3.

Desired behavior

A Cypress project based on a Yarn Modern Plug'n'Play (pnp) configuration, which previously ran successfully on Cypress 12.17.3, should continue to run successfully on later 12.x versions.

Test code to reproduce

See https://github.com/MikeMcC399/github-action/tree/test/yarn-pnp-update/examples/yarn-modern-pnp which is updated to use Cypress 12.17.4.

To run locally execute the following:

git clone --branch test/yarn-pnp-update https://github.com/MikeMcC399/github-action
cd github-action/examples/yarn-modern-pnp
npm install yarn@latest -g
yarn install
yarn run test

Cypress Version

12.17.4

Node version

18.17.1

Operating System

Ubuntu 22.04 (also reproducible on Windows 11)

This occurred while Cypress was compiling and bundling your test code. This is usually caused by:

- A missing file or dependency
- A syntax error in the file or one of its dependencies

Fix the error in your code and re-run your tests

Hi @MikeMcC399. I think I know what may be wrong. I am going to work on getting a binary ready for us to test with what I think might fix the issue

MikeMcC399 · 2023-08-17T17:38:43Z

@AtofStryker

Thanks for your progress note!

AtofStryker · 2023-08-17T18:38:28Z

OK I think I have this fixed. Binary works with local install. I have a fixed proposed in #27583

I would have like to have tested this whilst it was still a pending PR, however I couldn't work out how to do that for Yarn!

Now it's been merged and GitHub offers a beta I successfully tested on Windows 11. 👍🏻
