Supervisor doesn't work after installing from codebase (version 4.3)

[gcarabe]

Supervisor doesn't start after installing it from codebase, I get this error:

Traceback (most recent call last):
  File "/usr/bin/supervisorctl", line 33, in <module>
    sys.exit(load_entry_point('supervisor==4.3.0.dev0', 'console_scripts', 'supervisorctl')())

ModuleNotFoundError: No module named 'supervisor.supervisorctl'

After running the following commands:

sudo yum groupinstall "Development Tools"
sudo yum install python3-devel libpq git
sudo python3 -m venv /opt/supervisor
sudo /opt/supervisor/bin/pip install --upgrade pip
sudo git clone https://github.com/Supervisor/supervisor /opt/supervisor/bin/supervisor
sudo /opt/supervisor/bin/python3 /opt/supervisor/bin/supervisor/setup.py install
sudo /opt/supervisor/bin/pip install certbot-nginx multivisor[rpc]
sudo ln -sf /opt/supervisor/bin/supervisord /usr/bin/supervisord
sudo ln -sf /opt/supervisor/bin/supervisorctl /usr/bin/supervisorctl
sudo cp ./default-supervisord.conf /etc/supervisord.conf
sudo cp ./supervisord.service /lib/systemd/system/supervisord.service
sudo systemctl start supervisord
sudo systemctl enable supervisord
sudo systemctl daemon-reload

I am using default conf files. Am I missing something?

Try to import the module shown in the error message:

user@system sandbox % ./venv/bin/python3 
Python 3.12.2 (main, Feb  6 2024, 20:19:44) [Clang 15.0.0 (clang-1500.1.0.2.5)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from supervisor import supervisorctl
>>> ^D

No error.

Try to run supervisorctl:

user@system sandbox % ./venv/bin/supervisorctl --help
supervisorctl -- control applications run by supervisord from the cmd line.

Usage: ./venv/bin/supervisorctl [options] [action [arguments]]

Options:
-c/--configuration FILENAME -- configuration file path (searches if not given)
-h/--help -- print usage message and exit
-i/--interactive -- start an interactive shell after executing commands
-s/--serverurl URL -- URL on which supervisord server is listening
     (default "http://localhost:9001").
-u/--username USERNAME -- username to use for authentication with server
-p/--password PASSWORD -- password to use for authentication with server
-r/--history-file -- keep a readline history (if readline is available)

action [arguments] -- see below

Actions are commands like "tail" or "stop".  If -i is specified or no action is
specified on the command line, a "shell" interpreting actions typed
interactively is started.  Use the action "help" to find out about available
actions.

No error.

The error message ModuleNotFoundError: No module named 'supervisor.supervisorctl' comes from the Python packaging machinery trying to import the module. It occurred before any Supervisor code was reached. This is not a bug in Supervisor. The Supervisor developers do not have enough bandwidth to help troubleshoot installations on individual systems, sorry.
