uwsgi can't find python plugin

Question

I'm trying to deploy a python app to my Ubuntu 12.04.1 VPS running Nginx / uWSGI. I've setup my server following this guide. When I restart uWSGI I get this message:

nickd@my-vps:~$ sudo /etc/init.d/uwsgi restart  
[sudo] password for nickd:   
* Restarting app server(s) uwsgi  
[uWSGI] getting INI configuration from /usr/share/uwsgi/conf/default.ini  
[uWSGI] parsing  config file /etc/uwsgi/apps-enabled/application.net.xml  
open("./python_plugin.so"): No such file or directory [core/utils.c line 4700]  
!!! UNABLE to load uWSGI plugin: ./python_plugin.so: cannot open shared object file: No such file or directory !!!   Tue Dec 11

My application.net.xml:

<uwsgi>
    <plugin>python</plugin>
    <socket>/run/uwsgi/app/application.net/application.net.socket</socket>
    <pythonpath>/var/www/apps/application/</pythonpath>
    <app mountpoint="/">
        <script>wsgi_configuration_module</script>
    </app>

    <reload-on-rss>192</reload-on-rss>
    <no-orphans/>
    <vacuum/>
</uwsgi>

My INI config is default.

Any help getting uWSGI to load the python plugin would be appreciated.

Solution 1

I just ended up using Phusion Passenger to run my application. It was as simple as configuring and running Nginx.

Solution 2

You need to have the plugin installed.

sudo apt-get install uwsgi-plugin-python3

Solution 3

For ubuntu and python3: make sure the result of "which uwsgi" is: /usr/local/bin/uwsgi and remove the following settings in your .ini file: plugin=python3

Then try again.

"I used something else" is not a valid answer to this question.

This is the most accurate way to verify what is going but will still create a problem is you application needs a library that only exists in virtual environment

I'm sorry that if you don't use python virtual environment

[Priyanka Khadgi]

In fact I uninstalled uwsgi from virtual environment. Your answer is giving a valuable advice for debugging that's why I upvoted it
