Why is there an error with uWSGI no module named encodings?

Question

Django

uwsgi --ini uwsgi.ini Error
Fatal Python error: Py_Initialize: unable to get the locale encoding
ImportError: no module named 'encodings'
Aborted (core dumped)
In uwsgi.ini
[uwsgi]
chdir=/home/projects/ myproj
module=myproj.wsgi
home=/home/virtualenv
master=true
processes=10
socket=/home/projects/myproj/myproj.sock
vacuum=true
plugins=python34
chmod-socket=664
uid=www-data
gid=www- data
What am I doing wrong? Thank you very much in advance.
