Could not find a version that satisfies the requirement sip==4.19.2

[stoersignal]

when i try to install the coponents of reqs.txt with the command copied from your text i get this error message:
Could not find a version that satisfies the requirement sip==4.19.2 (from -r reqs.txt (line 3)) (from versions: )
No matching distribution found for sip==4.19.2 (from -r reqs.txt (line 3))

what to do?

Try changing the line to sip>=4.19.2 and try again. If that doesn't work, remove the line and try again.

If I remember correctly sip is used by python-rtmidi so it should grab sip automatically anyway. If not, let me know and I'll take a deeper look.
