Flask+Nginx+uWSGI : ImportError: No module named site

Question

I installed as the http://www.reinbach.com/uwsgi-nginx-flask-virtualenv-mac-os-x.html link's tutorial and when executing the command uwsgi --ini deploy/deploy.ini, the terminal says there was an import error:

Set PYTHONHOME to /virtualenv/sample/

ImportError: No module named site

I have set my PYTHONHOME and PYTHONPATH as

export PYTHONPATH=$PYTHONPATH:/Library/Python/2.7/site-packages
export PYTHONHOME=$PYTHONHOME:/Library/Python/2.7

I cannot figure out what wrong with it.

Could someone help me with the problem?

The whole info in the terminal is shown as below if it is helpful:

Set PYTHONHOME to /virtualenv/sample/

ImportError: No module named site

Answer 1

Here's how I resolved the same error message (ImportError: No module named site) that I got while trying the Django and NGINX tutorial — uWSGI 2.0 documentation.

Deactivate the virtualenv:

deactivate

Install uWSGI system-wide (if not already installed system-wide)

sudo pip install uwsgi

Edit the uwsgi.ini file. I commented out the line with the:

home = /path/to/virtualenv

Run uWSGI --ini mysite_uwsgi.ini.

Answer 2

I read a lot of document about the question, but get no answer.

By coincidentally, I fix this problem by edit uid and gid as root.

It seem like a permissions problem. I don't know why, but it just work. Remember, it is very unsafe to run a product environment as root.

Answer 3

1、active the virtual you used

2、 pip install uwsgi

this the key action，then the

command -v wsgi

show this

/virtual-path/bin/uwsgi

3、use current user to run uwsgi, because other user is not active the virtualenv

Answer 4

Im My case I wasn't using virtualEnv. Just using django + ngnix. My solution was removing HOME variable into the *.ini configuration file:

sudo nano /etc/uwsgi/sites/c_app.ini

[uwsgi]
    project = c_app
    uid = ubuntu
    base = /home/%(uid)

    chdir = %(base)/%(project)
    **home = %(base)/%(project)** (REMOVED IT)
    module = %(project).wsgi:application

    master = true
    processes = 5

    socket = /run/uwsgi/%(project).sock
    chown-socket = %(uid):www-data
    chmod-socket = 660
    vacuum = true

then it works.
