dev_tools/modules.py print_version fails with an error #5701
Description
Description of the issue
This report is a follow-up to a comment by @vtomole on PR #5637. The current version of dev_tools/modules.py exits with an error if given the argument print_version (which is one of arguments it is supposed to accept).
How to reproduce the issue
In a shell, with the current directory being the top level of the Cirq source code repo cloned from GitHub, run the following command:
python dev_tools/modules.py print_version
Failed to run ./setup.py:
