AttributeError: Extension instance has no attribute '_needs_stub' #707

Open felix-albrecht opened 2 years ago

felix-albrecht commented 2 years ago

When trying to install TLJH on my Ubuntu 20.04 server, I get the following error message:

File "/opt/tljh/hub/lib/python3.8/site-packages/setuptools/command/build_ext.py", line 209, in build_extension if ext._needs_stub: AttributeError: 'Extension' object has no attribute '_needs_stub'

The last message in /opt/tljh/installer.log is Upgraded pip.

This dependency issue is possibly a duplicate of this gRPC issue. I upgraded setuptools to the newest version (58.2.0) via pip and also replaced /opt/tljh/hub/lib/python3.8/site-packages/setuptools with the new, upgraded version, but the error persists.
