Python3 - PyQt6 installieren

[FrankM]

Immer wenn ich versuche PyQt6 zu installieren, bekomme ich merkwürdige Fehlermeldungen.

Error:  An error occurred while installing PyQt6!
ERROR: Could not find a version that satisfies the requirement PyQt6-Qt6>=6.2.2 (from PyQt6) (from versions: none)
ERROR: No matching distribution found for PyQt6-Qt6>=6.2.2 (from PyQt6)

Sauber läuft das nur, wenn das Paket pip aktuell ist. Also hier mal eine Vorgehensweise, wie man das sauber installiert.

env Umgebung bauen

pipenv --python 3.8

Danach, die Umgebung starten

frank@frank-MS-7C37:~/qsettings$ pipenv shell
Spawning environment shell (/bin/bash). Use 'exit' to leave.

pip aktualisieren

(qsettings-kBmIZW-V) frank@frank-MS-7C37:~/qsettings$ python -m pip install -U pip

Danach meckert auch nicht mehr, wenn ich ein PyQt6 Modul importieren möchte

from PyQt6.QtCore import QSettings
