Answer 1

You can try this next:

1. Remove yarn.lock.
2. Remove node_modules.
3. Use the --ignore-optional FLAG (yarn --ignore-optional); these don’t install optional dependencies.

The fsevents package is for macOS only; you don't need it in Linux.

If any of that works you can remove ignore and see if .yarnclean works.
