PermissionError: [Errno 1] Operation not permitted: '/Users/<local_path>/venv/pyvenv.cfg'

Question

I am running a Django application with a few cron tasks. Whenever I run python manage.py crontab add to register the cron tasks, I get a "mail" in the Terminal showing the following traceback:

Traceback (most recent call last):
  File "/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.7/lib/python3.7/site.py", line 609, in <module>
    main()
  File "/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.7/lib/python3.7/site.py", line 592, in main
    known_paths = venv(known_paths)
  File "/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.7/lib/python3.7/site.py", line 510, in venv
    with open(virtual_conf, encoding='utf-8') as f:
PermissionError: [Errno 1] Operation not permitted: '/Users/<local_path>/venv/pyvenv.cfg'

I am running on macOS Catalina, python 3.7.3 in a virtual environment venv.

I have tried giving full disk permission to bash, crontab, terminal, xcode and pycharm.

I have also tried installing python versions 3.7.8 and 3.8.3

Partially solved

I disabled System Integrity Protection using csrutil disable in Recovery Mode and the cron ran successfully. However, I do not see it as full solution.

Final solution

I dockerized the app and ran it as a docker container.

Answer 1

I was facing the same problem and after a few searching i found a error with cron permissions.

This is how i solved:

• Go to System Preferences -> Security & Privacy - Privacy -> Full Disk Access

• Click on the + icon to add an item

  If the lock appears locked, click on him to unlock with your user password

• Press Command + Shift + G to open a dialog

• Type /usr/sbin/cron and press Enter

• Search and select the cron file and click Open

Okay, now it should work.
