New Cargo versions sometimes write out a lockfile that triggers parse failures in old Cargo versions.
```console $ cargo +1.41.0 check ... Finished dev [unoptimized + debuginfo] target(s) in 0.91s
$ cargo +1.37.0 check error: failed to parse lock file at: /git/testing/Cargo.lock
Caused by:
invalid serialized PackageId for key package.dependencies
```
The cargo rm subcommand simply deletes the offending lockfile so that the old
Cargo can proceed. Install by running cargo install cargo-rm.
rm Cargo.lockcargo rm has three advantages:
It still works if run from a workspace member, where the lockfile would be located at the workspace root rather than the current directory.
It works if run from a subdirectory of a crate rather than the crate root.
If like me you use
export FIGNORE=argo.lock
in your shell so that all autocompletes prefer Cargo.toml over Cargo.lock,
this is easier to type.
