("Cloning luarocks failed.\nstderr: {}\nstdout: {}"):format(sc.stderr, sc.stdout),

Replace all with %s.

Remove color sequences

But even if I replace all with %s, the error message is pretty difficult to read due to the color sequences in the output.

I've added a wrapper function to remove the color sequences for a better visibility.
