Seahub failed to start #15684684

Hi there.
The install and initial config was straight forward. After configuring seahub it does not start. Seems like captcha module is making issues. Any idea?
What I did:

  • start-fastcgi
  • dir permission
  • dir ownership
  • re download & clean install
  • restart the server
  • different ports

LC_ALL is not set in ENV, set to en_US.UTF-8
Starting seahub (fastcgi) at …

ModuleNotFoundError: No module named ‘captcha’
Error:Seahub failed to start.

Did you install the python module captcha ?

Yes, i did. Installed every module with captcha but still no luck. I receive the same error.

Try to install the module for the specific python version:

python3.6 -m pip install captcha

I faced this problem on debian10 with python3.8. However, in my case it’s not related to non-installed modules. There are no reports in logs “ModuleNotFoundError:…”. It worked well and I guess that automatic debian update broke something.

Thank you. Worked! I had install pip to the Python 3.6… then install the ‘captcha’ module
