[Bug] Yarn 2.4.0 reading parent .pnp.js for pnpApi when enableGlobalCache is false

See original GitHub issue

I’d be willing to implement a fix

Describe the bug

I upgraded from Yarn 2.3.3 to 2.4.0 and am unable to run a yarn script in a child directory. I have the following folder structure:

package.json
yarn.lock
.yarn/releases/yarn-2.4.0.cjs
.yarnrc.yml
/lib/package.json
/lib/yarn.lock

As part of my root package I have pnpify installed so I can use eslint across all sub projects.

When you install the root, then enabled pnpify, then install lib, and then run any yarn command from the lib scripts you get the following error:

Internal Error: Unable to locate pnpapi, the module '/Projects/demo/lib/.pnp.js' is controlled by multiple pnpapi instances.
This is usually caused by using the global cache (enableGlobalCache: true)

To Reproduce

I’ve created a demo repo to reproduce the issue here. These are the steps to setup the demo and what to expect:

Setup Steps

Run yarn install in the root directory
Run yarn pnpify --sdk vscode to install the sdks
Run yarn install in the lib directory
Run yarn dev in the lib directory

You should receive the following error message when you run yarn dev:

Seems to be a bug here on our end, you can work around it by getting more specific with the pattern

pnpIgnorePatterns:
  - "./lib/.*"
  - "./lib/**"

Make sure to run an install after modifying .yarnrc.yml
