`plasmo dev` doesn't work in yarn pnp monorepo

I initialized a basic plasmo extension in the packages folder of our monorepo. we are using yarn plug'n'play so I tried running pnpify plasmo dev in the script. But I get this error ERROR | EROFS: read-only filesystem, open '/node_modules/@plasmohq/parcel-config/run.json' I tried running it with verbose and get this.

 EROFS: read-only filesystem, open '/node_modules/@plasmohq/parcel-config/run.json'

Does plasmo just not supports this? I can't find anything online about these error messages. Any ideas/info about pnp support with plasmo?

It looks like parcel is unintentially trying to write the virtual fs yarn creates?

I encounter the same issue. I told yarn to unplug @plasmohq/parcel-config but then I'm stuck with another error:

I've found a workaround: in your root package.json, add:

  "dependenciesMeta": {
    "@plasmohq/parcel-config": {
      "unplugged": true
    },
  }

  "dependenciesMeta": {
    "@plasmohq/parcel-config": {
      "unplugged": true
    },
  }

Then, in your .yarnrc.yml:

packageExtensions:
  '@parcel/node-resolver-core@*':
    dependencies:
      '@parcel/core': '*'

packageExtensions:
  '@parcel/node-resolver-core@*':
    dependencies:
      '@parcel/core': '*'

` It works like a charm for me. I'm using plasmo v0.82.1
