Wie installiere ich Pandas, wenn PIP aufgrund eines Fehlers bei der Metadatengenerierung fehlschlägt? ⇐ Python

[Anonymous]

Ich versuche, Pandas in einer eigenständigen Installation von Python 3.12 zu installieren und erhalte ständig die Fehlermeldung „Metadatengenerierung fehlgeschlagen“. Ich kann Pandas in meiner Anaconda-Installation installieren, aber ich muss dieses vollständig separat installieren, da ich es zum Herstellen einer Verbindung zu VB.net verwende. Ich habe PIP und die Setup-Tools aktualisiert und erhalte die gleiche Fehlermeldung. Wie kann ich Pandas installieren?


Der Installationsbefehl und die Ausgabe lauten wie folgt:

Code: Select all

C:\Program Files (x86)\Python312-32\Scripts>pip install pandas
