I feel your message is just a complaint, not issue report.
You didn't report any concrete information about your environment. (e.g. How did you install Python, which bash do you use, `env` output, `which python` output, etc...)

Your message made I feel bad, without any useful information.
If you really want to fix your environment, you can use other place (python-list, stackoverflow, or something else).

I think we can improve error message, but I don't want to keep using this issue.
May I close this issue?
