Why aren't encodings and uwsgi-plugin-python3.7 installed for the virtualenv?

Question

Django

Hello. I'm trying to set up a uwsgi+django bundle on a debian 10 server.
Path to python virtual environment:
/home/daniil/projects/django/xiaomi_project
When trying to run:

uwsgi --ini /home/daniil/projects/django/xiaomi_project/xiaomi/xiaomi.ini

Gives the following error:

[uWSGI] getting INI configuration from /home/daniil/projects/django/xiaomi_project/xiaomi/xiaomi.ini
open("./python37_plugin.so"): No such file or directory [core/utils.c line 3724]

The encodings module for python3.7 and the python3.7_plugin.so plugin for uwsgi are installed globally.
When trying to set encodings in an activated virtualenv, an error occurs:

Could not install packages due to an EnvironmentError: 404 Client Error: Not Found for url: https://pypi.org/simple/encodings/

Similarly with the installation of uwsgi-plugin-python3.7.:

Could not install packages due to an EnvironmentError: 404 Client Error: Not Found for url: https://pypi.org/simple/uwsgi-plugin-python3-7/

The following is written in the xiaomi.ini configuration file:

[uwsgi]
    chdir = /home/daniil/projects/django/xiaomi_project/xiaomi
    env DJANGO_SETTINGS_MODULE = xiaomi.settings
    module = xiaomi.wsgi:application
    socket = 127.0.0.1:8001
    plugins = python37
    home = /home/daniil/projects/django/xiaomi_project/xiaomi

Can you tell me how I can install the required module and plugin?
I will be glad for any help.

Answer 1

I don't bother with plugins and put uwsgi inside a virtual environment.
I always call the django project app, put the ini file next to manage.py + the built-in variable %d and get a minimum of settings and they are almost the same for any project:

[uwsgi]
chdir = %d
wsgi-file = %dapp/wsgi.py
...
#остальные ваши переменные
# а env, module, plugins и home не нужны
