Python 找不到已安装的模块

Question

Python3.5 does not locate installed modules when invoked in virtual env.

1. Create virtual env: python3.5 -m venv autogit/venv && cd autogit
2. source venv/bin/activate
3. which python == ...autogit/venv/bin/python Weird, would expect python3.5
4. Add my python source code to /autogit and pip freeze>requirements.txt
5. pip install -r requirements.txt
6. ls venv/lib/python3.5/site-packages shows request-0-0-0-py3.5.egg-info and some other stuff
7. Since dependencies are installed under python3.5 and which python revealed python rather than python3.5 , lets invoke the python3.5binary explicitly.... venv/bin/python3.5 autogit.py Get ImportError: No module named 'request

??? Where could python be looking for packages if not in my virtual env?

UPDATE The questions above remain unanswered; here are things I noticed since then and the workaround I used:

• pip install produced a file request-0-0-0-py3.5.egg-info . It did NOT produce an actual request directory with the source code or binaries for this module. Also why is it version 0 0 0 that is fishy

• After some googling I noticed the module I wanted seemed to be named requests not request which is what was in my source. I changed it requests, pip install , and everything works. It was hard to see that there was a mistake because pip install ing request did not fail

Have you got other Python versions installed? That might be the problem.

Try using pip3 instead of pip
