Cypress does not detect required dependencies during launch with Yarn 3 in PnP mode

[pondchamp]

Current behavior

[Similar issue to what was mentioned in a discussion thread (#27263), though it never got any responses]

I recently started encountering a missing dependency error when launching Cypress with Yarn 3.2.3 in PnP mode (see debug logs).

I tried reverting to Cypress 12.3.0, but I get the same error except for lodash instead of @opentelementry\resources.

I discovered that temporarily setting nodeLinker: node-modules on my .yarnrc.yml file allows Cypress to launch successfully, though it isn't very practical for development purposes given our entire site uses PnP. Is there anything I can do to get Cypress working in PnP mode?

Desired behavior

Application should launch without needing to use node_modules linker

Test code to reproduce

1. Create a React app with Yarn 3 on PnP linker mode
2. Install and launch Cypress

Cypress Version

13.13.2

Node version

v16.20.2 (also tested with Node v18.x)

Operating System

Win11 22631.3880

• This issue has been reported before. See cypress run fails when installed using yarn 3.x on apple silicon mac #27542 (comment) and the resolution was to check for .pnp.cjs in the home directory and remove it if found. It does not appear to be a Cypress bug as such. Possibly this issue is resolved in Yarn 4 (current version 4.4.0). You could check with the Yarn experts about this, for instance via https://discord.gg/yarnpkg.

PS Sorry for my incorrect post linking this issue to Component Testing, which I deleted after posting, since it was irrelevant.

Thanks for the help @MikeMcC399! I did some digging and .pnp.cjs was indeed my issue - though to generalise the solution here, I found that having this file at my drive root was the cause of my issue, so I think it's just a matter of having the file in any parent directory. Will look into the yarn upgrade to see if it also resolves the issue!

Did you solve this problem? 🤔

I'm using the yarn monorepop mode. (yarn version: 4.5.1)

I'm using m1 apple silicon and I get the same error. 😱
