uWSGI: No request plugin is loaded, you will not be able to manage requests

unable to load uwsgi plugin

I've loaded uWSGI v 1.9.20, built from source. I'm getting this error, but how do I tell which plugin is needed?

!!!!!!!!!!!!!! WARNING !!!!!!!!!!!!!!

you may need to install the package for your language of choice, or simply load
it with --plugin.
!!!!!!!!!!! END OF WARNING !!!!!!!!!!

Which plugin should be loaded?

I had this problem and was stuck for hours.

my issue is different than the answer listed, make sure you have plugins = python in your uwsgi ini file and you install the uwsgi python plugin:

sudo apt-get install uwsgi-plugin-python

After I did the above my application worked. Obviously this is for python projects, but a similar approach is required for other projects.

uwsgi : doesn't detect plugins, no request plugin is loaded, you will not be able to manage requests. you may need to install the package for your language of choice, or simply  no request plugin is loaded, you will not be able to manage requests. you may need to install the package for your language of choice, or simply load it with --plugin.

It might be easiest to install uwsgi through pip instead of the package manager from the OS you're using, the package in pip is usually more up to date than the package managers from the OS you might be using:

sudo pip install uwsgi

This solved it for me anyway.

For using multiple Python versions on the same server, I would advice to take a look at virtualenv: https://virtualenv.pypa.io/en/latest/

Just stumbled upon this error message and wasted a couple of hours, yet in my case the cause was different from everything mentioned in other answers already.

Suppose you just installed a local uWSGI version via pip into your own virtualenv (e.g. as described here).

Suppose you are now trying to run your uWSGI server as root (because you want to serve the app as www-data user, for example). This is how you would do it, right?

. venv/bin/activate
sudo uwsgi --ini your-app.ini

Wrong! Even though your local uwsgi is in your path after you activated your environment, this path is not passed into the sudo command, and you are launching the system uwsgi rather than your local one, which may be the source of endless confusion, like it was in my case.

So, the solution in my case was to simply specify the full path:

sudo /full/path/to/venv/bin/uwsgi --ini your-app.ini

If you've followed all the python plugin installation steps and uwsgi --plugin-list still fails to list 0: python as one of the plugins, try restarting your computer. My uwsgi instance ran as a service (from Bash, use service status-all to see running services) and probably the updated config settings were loaded on service restart.

As we have seen, uWSGI is composed of a small core and various plugins. Plugins can be embedded in the binary or loaded dynamically. When you build uWSGI for Python, a series of plugins plus the Python one are embedded in the final binary. This could be a problem if you want to support multiple Python versions without building a binary for each

Comments
  • how have you built uWSGI ? it is pretty uncommon to build using a profile without a specific language (unless you are making a distro package)
  • I'm trying to compile uWSGI, then separately compile explicit Python plugins so that I can use multiple Python versions. When doing it like this, not enough plugins are built it seems, so I need to know the list of typical plugins. It looks like the .ini files in /buildconf give a clue to that.
  • just putting plugins = python into the ini sorted this out.
  • plugins = python3 in the uwsgi vassal .ini file if your using the python3 plugin that is, you can ls /usr/lib/uwsgi/plugins/ to get a list of valid plugin names, minux the _plugin... suffix.
  • for python3 install uwsgi-plugin-python3 and use plugins = python3
  • In my case I already had Debian's version of uwsgi installed before I installed pip's, so I had to make sure to create a symbolic link from /usr/bin/uwsgi to /usr/bin/local before it worked properly.
