Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding, when trying to start uwsgi
Solution 1
I see your PYTHONHOME is set to PYTHONHOME = '/home/env3/educ'
. Try to check if it is really there.
The solution for me was to remove the PYTHONHOME
environment variable.
For you, it can be just that, or setting that variable to another value.
This worked on Windows, and would work on Linux for sure. If someone tries this, please post a comment here !
A CPython developer confirmed the solution here. :
This is not a Python bug, this is a symptom of setting PYTHONHOME and/or PYTHONPATH when they’re not needed. In nearly all cases you don’t need to set either of them;
In the case of PYTHONHOME it’s almost always a mistake to set.
Solution 2
I solve this problem by unsetting PYTHONHOME or PYTHONPATH, because they override the virtual environment variables.
In my case this is caused by my admin's base environment. I would try removing PYTHONHOME and PYTHONPATH variables by doing
unset PYTHONPATH
unset PYTHONHOME
Solution 3
This message is for those with the same problem who will find this page later. I couldn't start uWSGI with my config, and I had the same message in logging files.
init_fs_encoding: failed to get the Python codec of the filesystem encoding Python runtime state: core initialized ModuleNotFoundError: No module named 'encodings'
The problem was uWSGI didn't have enough permissions to access the virtual environment. When I fixed the permissions, uWSGI started my config.
Denys posted the uwsgi.ini config in his message. I guess the path to the virtual environment is wrong.
base = /home/env3/educ
projectname = educ
virtualenv = /home/env3/%(projectname)
If the virtual environment was created in the project directory, then the path should look like this:
virtualenv = /home/env3/%(projectname)/env

I am trying to start my uwsgi server in my virtual environment, but after I added
plugin python3
option I get this error every time:!!! Python Home is not a directory: /home/env3/educ !!! Set PythonHome to /home/env3/educ Python path configuration: PYTHONHOME = '/home/env3/educ' PYTHONPATH = (not set) program name = '/home/env3/educ/bin/python' isolated = 0 environment = 1 user site = 1 import site = 1 sys._base_executable = '/home/env3/educ/bin/python' sys.base_prefix = '/home/env3/educ' sys.base_exec_prefix = '/home/env3/educ' sys.executable = '/home/env3/educ/bin/python' sys.prefix = '/home/env3/educ' sys.exec_prefix = '/home/env3/educ' sys.path = [ '/home/env3/educ/lib/python38.zip', '/home/env3/educ/lib/python3.8', '/home/env3/educ/lib/python3.8/lib-dynload', ] Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding Python runtime state: core initialized ModuleNotFoundError: No module named 'encodings' Current thread 0x00007efe89db8780 (most recent call first): <no Python frame>
Also I tried to create new virtual environment using
python3 -m venv env
and moved project files to it, but still the same error. Here is my uwsgi.ini file:[uwsgi] base = /home/env3/educ projectname = educ plugins = python3 master = true virtualenv = /home/env3/%(projectname) pythonpath = %(base) env = DJANGO_SETTINGS_MODULE=%(projectname).settings.pro module = %(projectname).wsgi:application socket = /tmp/%(projectname).sock chmod-socket = 666
I use Python 3.8.5
I am trying to use Django + uWSGI + nginx + Postgresql
If you need more details I will give it
Thank you

CrmXao over 2 yearsIn the terminal, it unsets the PYTHONPATH and PYTHONHOME, "unset" is a terminal command

James.L over 2 yearsok so i deleted python from my pc and then reinstalled it and its working again, although I do have to reinstall all my pip libraries now

vvvvv about 2 yearsIn my case, I added a
/bin
at the end of the virtualenv path, and that is what was causing the error.
