As a developer I should be able to install rust using ./x.py install

However, when I run the command I get...

sudo RUST_BACKTRACE=1 ./x.py install
info: looks like you are running this command under `sudo`
      and so in order to preserve your $HOME this will now
      use vendored sources by default.

@purejgleason this is probably #76720 - if you run rm -r build/x86_64-unknown-linux-gnu/stage1-rustc/x86_64-apple-darwin/release/incremental does it fix the issue?

rm: build/x86_64-unknown-linux-gnu/stage1-rustc/x86_64-apple-darwin/release/incremental: No such file or directory

I will look more at the link. Also will try deleting the full build since it is not in the repo

If that doesn't work, try rm build/x86_64-apple-darwin/stage1-rustc/ - that should clear less than a full x.py clean.

@purejgleason are you still running into trouble with this?

I'm going to close this since it's likely a duplicate of #76720.
