OSError: [Errno 2] No such file or directoryThis example comes from an Android system lacking pip or git binaries. I believe the error is legit, as we simply call subprocess.Popen("git xxx"), which should AFAIK blow up on any system lacking Git.
Why this didn't come up before now is probably due to the following:
- This function is only called at install time or during
fab --version (and --version is likely rarely invoked)
- Most devs have Git installed somewhere, in which case this will not blow up even if they're not running in a Git checkout (instead, the Popen call will just register a nonzero exit). This is why the call does
git_sha() or xxx.
EDIT: Except that should still result in a shell level error (eg bash: git: file not found) and not OSError -- so this might meant Popen itself cannot open the shell it's trying to use (should be /bin/sh by default). Which makes a lot more sense on Android vs other systems.
Fix should be a simple try/except either way.
