Hello, I am trying to build LiberTEM
https://build.opensuse.org/package/show/home:andythe_great/LiberTEM

The package failed.
I assume that it is trying to use python2 to execute setup.py but shouldn’t python3 be use? I don’t add any python2 package. How to make it use python3?

Thanks

Hi
Then just use /usr/bin/python3

Thanks it work.

But do I have to run a test to build a package which it seems what setup.py test is trying to do.
