same problem and solved by installing cmake

[whereistejas]

Cool. It didn't occur to me that, that could be the problem.

[zhengweidi]

take a look at your error message:

--- stderr
fatal: Not a git repository (or any of the parent directories): .git
thread 'main' panicked at '
failed to execute command: No such file or directory (os error 2)
is cmake not installed?

It already tells you the problem.

@sanaptejas Has this fixed your issue?
In an unrelated note, why are you running the command as sudo? By default the installed files
are written to your home dir and should not require elevated rights.

[whereistejas]

yes installing cmake solved my problem

[dsego]

IMO, this requirement should be documented in the installation instructions.
