Rye::Cmd.rm sometimes fails to remove recursive directories

[rajsahae]

I have a method which simply removes an entire directory.

def remove_cache
  # Remove the cache
  begin
    @system_rye.disable_safe_mode
    @system_rye.rm(:r, :f, @@cache_path)
  ensure
    @system_rye.enable_safe_mode
  end
end

Sometimes, seemingly random, the remove method will raise an errer and claim to be unable to remove the directory.

Hmm, the error message is coming from the rm command and not rye itself. The only thing I can think of is that somehow the -r -f flags aren't being passed along. If it happens again, run rye with debugging enabled and send that output (Rye::DEBUG=true).
