When I use gunicorn to deploy the project, I can't find the module. When I use the test environment it is normal.

Traceback (most recent call last):
      File "/usr/lib/python2.7/site-packages/gunicorn/arbiter.py", line 583, in spawn_worker

My guess is that flask_script is installed as part of your global environment and not as part of your virtual environment. Can you do a pip show Flask-Script?

  • I use pip freeze to query all modules in the virtual environment ```Name: Flask-Script Version: 2.0.5 Summary: Scripting support for Flask Home-page: http://github.com/smurfix/flask-script Author: Dan Jacob Author-email: danjac354@gmail.com License: BSD Location: /root/home/.virtualenvs/flask_py2/lib/python2.7/site-packages Requires: Flask Required-by: ``` – 1am9a09e May 23 '18 at 03:09
  • So your gunicorn is using your os' python environment `/usr/lib/python2.7/site-packages/ ` but flask-script is installed as part of your virtual environment? `/root/home/.virtualenvs/flask_py2/lib/python2.7/site-packages` Try it with both in the same environment – user2797437 May 23 '18 at 03:17
  • I uninstalled gunicorn in a formal environment and solved this problem. : P – 1am9a09e May 23 '18 at 05:55
