uWSGI Fails with No module named encoding Error

Check that

virtualenv = /root/path/to/virtualenv

points to the right path. I solved my error by fixing this mistyped path.

in my case it was basically because I used python 2.7 as main interpreter, and uwsgi choose pyhon3 plugin. You might need to force it using:

plugins=python32

where python32is appropriate name for your pythhon3 plugin.

Have you checked this: uwsgi python3 plugin doesn't work?
