Wie installiere ich das Modul PyQt5 unter MacOS Catalina?

Gemäß gibt es 2 Optionen:

Option 1: Mac OS X binary "PySide" siehe Link [2]

Option 2: den Befehl "brew install pyqt", siehe Link [1]

Option 1:
Wenn ich das Mac OS X binary installieren möchte, kriege ich die Fehlermeldung, dass mein Betriebssystem zu aktuell dafür ist.

Option 2:
Ich probierte es mit

Code: Alles auswählen

brew install pyqt

Ausgabe Meldung Terminal siehe unten unter [3].

Ich erhalte aber weiter die Fehlermeldung:

Code: Alles auswählen

Laptop:Anwendung_Python myname$ python3 __init__.py
Traceback (most recent call last):
  File "__init__.py", line 5, in <module>
    from PyQt5 import QtCore, QtGui, QtWidgets
ModuleNotFoundError: No module named 'PyQt5'

A CA file has been bootstrapped using certificates from the system
keychain. To add additional certificates, place .pem files in
  /usr/local/etc/openssl@1.1/certs

and run
  /usr/local/opt/openssl@1.1/bin/c_rehash

openssl@1.1 is keg-only, which means it was not symlinked into /usr/local,
because macOS provides LibreSSL.

If you need to have openssl@1.1 first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"' >> ~/.bash_profile

For compilers to find openssl@1.1 you may need to set:
  export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"

PyQt ist also installiert fuer ein python3.8 das von *brew* extra installiert wurde. Und das musst du dann auch benutzen. Und da steht auch, wie man es einrichtet, das man das starten kann. Und kannst wenn du willst auch ein anderes Python 3.8, das du ggf. installiert hast, entfernen, und nur das brew python benutzen. Wuerde ich dir raten.

Danke schön, diese Info konnte ich nicht herauslesen!
