Gunicorn 23.0 Django 5.1 ModuleNotFoundError: No module named 'cloudmonitor.wsgi'

[juparker37]

Hello:

I have been struggling for two days now to migrate from Django runserver to Gunicorn for production. I have read through the Guincorn settings and built a config file and I continue to get the error ModuleNotFoundError: No module named 'cloudmonitor.wsgi' even though the Django wsgi.py seems to be correct. I have tried to run "gunicorn -c gunicorn.conf.py cloudmonitor.wsgi:application" in /home/jparker/, /home/jparker/cloudmonitor, /home/jparker/cloudmonitor/cloudmonitor, even in the directory with manage.py as noted in https://docs.gunicorn.org/en/stable/run.html#django.

`[2024-08-15 15:42:09 +0000] [2454119] [ERROR] Exception in worker process Traceback (most recent call last): File "/usr/lib64/python3.11/logging/config.py", line 573, in configure handler = self.configure_handler(handlers[name]) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib64/python3.11/logging/config.py", line 757, in configure_handler result = factory(**kwargs) ^^^^^^^^^^^^^^^^^ File "/usr/lib64/python3.11/logging/handlers.py", line 155, in init BaseRotatingHandler.init(self, filename, mode, encoding=encoding, File "/usr/lib64/python3.11/logging/handlers.py", line 58, in init logging.FileHandler.init(self, filename, mode=mode, File "/usr/lib64/python3.11/logging/init.py", line 1181, in init StreamHandler.init(self, self._open()) ^^^^^^^^^^^^ File "/usr/lib64/python3.11/logging/init.py", line 1213, in _open return open_func(self.baseFilename, self.mode, ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ FileNotFoundError: [Errno 2] No such file or directory: '/opt/djangoprojects/reports/bin/gunicorn.errors'

The above exception was the direct cause of the following exception:

I have read countless Stackoverflow posts, Reddit, posted on Django forums and still unable to resolve the issue. I am wondering if this is a bug.

Below are the details of my Gunicron config file, Django wsgi.py, settings.py and environment information.

The pythonpath with an entry where two consecutive directories carry the same name, and the one containing /bin/ (what?) makes me think you are launching gunicorn without chdir or configuring venv, yet the directories your import paths refer to are not part of your pythonpath.

Are you talking about the gunicorn.conf.py file with pythonpath? I am not using a venv as this project runs in the /home/ directory and global python is 3.11.
