Updating crates.io index
error: corrupted loose reference file: refs/heads/master; class=Reference (4)
Why does it mean? how to know this error?
Hello, I'm pretty new to Rust but I would like to share these links with you:
Looks like some git repository which cargo depends on has been corrupted.
If you run a simpler command, like cargo update, does the same error occur?
If so, then it's probably a corrupted registry (similar to this cargo issue). If this is the case, then the best solution is to delete the .cargo/registry/index folder.
This could also be an intermittent error, caused by a network error. Does it still error if you run the same command again?
Probably a registry update has been interrupted at an unfortunate moment. Run:
rm -rf ~/.cargo/registry/index/
