Research direction

Start by reproducing the setup with a home and project .yarnrc.yml containing different yarnPath values, then run yarn --version from the project. Trace Yarn's configuration resolution to determine why the home file wins; done means the closest project configuration takes precedence and the reported version is 2.3.1.

Description

bug external bug upholded

Describe the user story

If I have:

  • ~/.yarnrc.yml (home directory Yarnrc file) with yarnPath pointing to e.g. v1.22.10
  • ~/project/.yarnrc.yml (project-level Yarnrc file) with yarnPath pointing to e.g. v2.3.1

Then cd ~/project && yarn --version should yield version 2.3.1, not 1.22.10.

Describe the solution you'd like

Respect the closest Yarnrc file – it should have higher priority / take precedence over my global config.

Describe the drawbacks of your solution

Not sure if home directory's Yarnrc file isn't special somehow. Maybe some people depend on the current behavior?

Describe alternatives you've considered

N/A

Additional context

This was a major gotcha for one of my colleagues today, hard to debug. We were not sure why Yarn "misbehaves" when everything seemed correct. It turned out that there was a yarnPath in the home directory and that has overwritten our project setup.
