We had a check allowing the
renameoperation to fail for tarballs, but forgot to do the same for the single JS file downloaded in the Yarn codepath. As a result the operation could fail when two processes are downloading the exact same version. I got this error on Netlify when trying to install multiple git dependencies from the same repository.Unfortunately no tests, as it's a race condition so not sure I can easily test that without making the tests flaky 🫤
