lock file version 4 requires -Znext-lockfile-bump

[619]

I get lock file version 4 requires -Znext-lockfile-bump when I try to run anchor build. I've tried everything chatGPT has suggested and it's still there.

It seems like the newer Rust nightlies have bumped Cargo lock file to version 4.

You can workaround this problem by downgrading the changing the lock file version from 4 to 3.

How do you change the lock file version on the command line?
