Not sure if this information is helpful or not, but I am running into this with a monorepo. I recently migrated several applications into a yarn workspace monorepo. Some of the applications have the same version of cypress, some have a different version. Running yarn on circle ci results in various issues around downloading and/or unzipping cypress (probably not happening locally since each version was previously installed individually before migrating to the monorepo). Some of the error messages I have seen (expand for more output):

There are several more like the first one, just with different versions and/or different missing files.

Individually/independently, before being combined into workspace / monorepo, these all worked.

To me, not really knowing how yarn works and how the download / install works, but for the checksum it seems like a race condition where the zip file is either being created or removed while another install is trying to access it. I see it uses process.pid when naming the zip, I just don’t know if yarn workspace is creating a new process for each install or not. If it doesn’t, that would definitely lead to collisions.

Maybe for the missing files maybe one install determines that the cache is there and tries to use it as another install is unzipping the cache (so the files are not all there yet and thus, depending on the exact timing, a different file is missing and causes the error)
