addon Manager under Linux: out of work, tried BIM installation

[HobbyKritzler]

Hi!
I pulled FreeCAD 0.21.0, Libs: 0.21.0R31529 (Git), compiled, installed and started FreeCAD.
OS: openSuse 15.3

As soon as the addon manager is opend in the python terminal these lines appeare:

I assume that the BIM installation does not work due to these error messages:

I hope it is easy to fix.
Please advice if more info is needed.

[chennes]

Could you please post your complete About... info? In particular, what version of Python?

[HobbyKritzler]

Hi Chennes,
sorry I missed your request.

I pulled several times since the first post, hoped that the implemented changes fixed it.

Your Python is too old: you need at least 3.8 to work with 0.21-dev. Actually, cMake should have told you that, so it is strange that it did not.

[HobbyKritzler]

For me strange is the link to 2.7 but 3.9.15 detected by cmake!
