Mac gcloud install ImportError: No module named __future__

Question

When installing gcloud for mac I get this error when I run the install.sh command according to docs here:

Traceback (most recent call last):
  File          


        

Answer 1

The script uses the -S command-line switch, which disables loading the site module on start-up.

However, it is a custom dedicated site module installed in a virtualenv that makes a virtualenv work. As such, the -S switch and virtualenvs are incompatible, with -S set fundamental imports such as from __future__ break down entirely.

You can either remove the -S switch from the install.bat command or use a wrapper script to strip it from the command line as you call your real virtualenv Python.
