uWSGI Fails with No module named encoding Error

问题

I am trying to setup uWSGI with Pyramid, but I am getting this error, when attempting uwsgi --ini-paste development.ini

Python version: 3.2.3

Error message:

uwsgi socket 0 bound to UNIX address /tmp/uwsgi.sock fd 3
Python version: 3.2.3 (default, Oct 19 2012, 20:08:46)  [GCC 4.6.3]
Set PythonHome to /root/path/to/virtualenv
Fatal Python error: Py_Initialize: Unable to get the locale encoding
ImportError: No module named encodings

Here is what I have in development.ini

[uwsgi]
socket = /tmp/uwsgi.sock
master = true


processes = 4

harakiri = 60
harakiri-verbose = true
limit-post = 65536
post-buffering = 8192

daemonize = ./uwsgi.log
pidfile = ./pid_5000.pid

listen = 256 

max-requests = 1000

reload-on-as = 128 
reload-on-rss = 96
no-orphans = true

log-slow = true
virtualenv = /root/path/to/virtualenv

I suppose I have checked everything possible, including the following

echo LANG:$LANG LC_CTYPE:$LC_CTYPE
LANG:en_US.UTF-8 LC_CTYPE:

I am using virtualenv and uWSGI was installed while the environment was active. I have also checked that my virtual environment's lib has a package named encoding (pointing to my main python3.2 installation)

I have also checked this answer and this

I had previously installed uWSGI when my virtualenv was not active, but then I installed it properly and removed the executable and py files from previous installation.

Is there a way to get detailed logs, please let me know if there is. Thanks in advance

回答1:

in my case it was basically because I used python 2.7 as main interpreter, and uwsgi choose pyhon3 plugin. You might need to force it using:

plugins=python32

where python32is appropriate name for your pythhon3 plugin.

Have you checked this: uwsgi python3 plugin doesn't work?

回答2:

Check that

virtualenv = /root/path/to/virtualenv

points to the right path. I solved my error by fixing this mistyped path.

回答3:

Just had the same problem. What I realized afterwards was that I installed uwsgi with pip install uwsgi in the virtualenv. Once I left the virtualenv, I installed uwsgi on the local system with pip3 install uwsgi (notice I wrote pip instead of pip3). So I uninstalled with pip3 uninstall uwsgi and I repeated with pip install uwsgi. Worked like a Charm.

I also met this problem today, and I tried to set plugins=python34, but it did not work on Ubuntu 14.04 and Python 3.4.3

This is what I did to fix it:

sudo pip uninstall uwsgi
something goes wrong when i run sudo pip install uwsgi, and run this first:

sudo apt-get install python-dev
(sudo)pip install uwsgi

回答5:

Run uwsgi command (with your options) just like the following line:

/<path-to-your-virtualenv-bin>/uwsgi --http :8008 --module project.wsgi --venv /<path-to-your-virtualenv> --chdir /<path-to-your-project>

You will find the issues.

Did you miss your module param?

回答6:

I encountered a similar error message, but with a python version variation:

Python version: 3.4.3 (default, Nov 28 2017, 16:44:58)  [GCC 4.8.4]

This came about from trying to use a python3.6 virtual environment, but uwsgi being setup for python3.4. I re-setup the virtual environment using python3.4 and all was well.

回答7:

Building upon Edward's answer, I instead reinstalled uWSGI with pip3.6 instead of pip3, Python 3.4.8 being the default Python 3 on the server:

$ python3 --version
Python 3.4.8
