Django ModuleNotFoundError：没有名为“asgiref”的模块

Question

I have a Django service we are trying to schedule in conjunction with the main application that runs periodically to send automated emails via a batch script.

The Django application itself starts up fine, but when I try running the batch script, I get the following traceback:

Traceback (most recent call last):

ModuleNotFoundError: No module named asgiref

I find that odd considering I have the batch file set to run from an anaconda environment that has Asgiref installed. I can verify this with pip freeze. Here are the versions of the packages I'm using:

asgiref==3.3.1
Django==3.1.6

I saw a similar issue here , that was due to the Django and asgiref packages being outdated. I've tried updating both asgiref and Django to the latest versions (those listed), but that also didn't help.

My best guess after looking through the traceback is either something is trying to use a deprecated package (hence the use of deprecation.py) or a path needs to be appended somewhere. If the former, is there an alternative I should be using?

For reference, here is the batch file I am trying to use:

call C:\ProgramData\Anaconda3\Scripts\activate.bat C:\ProgramData\Anaconda3 
call activate test
"C:\ProgramData\Anaconda3\Python.exe" "C:\Program Files\compuweather\compuweather\webapp\management\commands\send_all_clients.py"

Answer 1

You can use manage.py to run your custom management command from your batch and have access to your project environment:

python C:\Program Files\compuweather\compuweather\manage.py send_all_clients
