ImportError: attempted relative import with no known parent package

[pulkomandy@…]

I get this error when starting the fcgi server:

/usr/lib/python3/dist-packages/trac/web/fcgi_frontend.py:19: DeprecationWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html
  import pkg_resources
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/trac/web/fcgi_frontend.py", line 51, in <module>
    from ._fcgi import WSGIServer
ImportError: attempted relative import with no known parent package

I fixed the problem locally by changing the import to use an absolute path:

   from trac.web._fcgi import WSGIServer

This is with python 3.12 if that makes any difference.

Thanks for the reporting.

Workaround is to run as a module instead a script:

$ python -m trac.web.fcgi_frontend
