uWSGI Fatal Python error: Py_Initialize: Unable to get the locale encoding

I've seen at least 3 questions about this problem.

  1. Virtualenv (Python 3.2)
  2. Django project in this env
  3. uWSGI

But I have plugins = python3 in uWSGI settings file and it's ok!
Server is started, everything is working...
Restart server - and everything is still working...
Reload server (or touch reload-file) and you have this error:

Fatal Python error: Py_Initialize: Unable to get the locale encoding
ImportError: No module named encodings

Even more... I have another project in another Env and touch reload-file works for it.
Any suggestions why can this happen?

PS: I tried to create a new virtualenv

Logs:

After service uwsgi restart:

Update 1

It is definitely virtual env. Copying my old VEnv and using didn't cause this problem.
Still have no idea why a newly created one doesn't work.
Copying only python executable didn't help.

I don't know exactly what happened since I did a lot of things:

  1. System upgrade
  2. New python environment
  3. Python version 3.3, not 3.2
  4. uwsgi 1.2.4 system package (perhaps this helped)
    or better use pip install uwsgi in your VE and run what you need with supervisord

Now it's working. Thanks roberto.
