Hallo,

ich habe Probleme beim Installieren des mariadb-Moduls für python. Nach Eingabe von:

Code: Alles auswählen

pip3 install mariadb
erhalte ich folgende (mir) nichtssagende Fehlermeldungen:

Code: Alles auswählen

WARNING: The directory '/home/martin/.cache/pip' or its parent directory is not owned or is not writable by the current user. The cache has been disabled. Check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

Nun weiß ich nicht, was da das Problem ist. Wichtig wäre eventuell zu erwähnen, dass neben Python3.7 bei mir auch noch eine Python2 Version installiert ist.

Vielleicht kann mir jeand helfen. Ich würde mich freuen.

Die Fehlermeldung ist doch eindeutig. Du mußt auch noch MariaDB Connector/C installieren. Das ist eine C-Bibliothek, die Du entweder in den Paketen Deiner Distribution findest, oder selbst kompillieren mußt.

Du mußt wahrscheinlich noch das libmariadb-dev-Paket installieren, weil sonst kann man die Bibliothek nur benutzen und nicht Programme übersetzen.

Danke dir erstmal für deine Ratschläge.

Wir kommen der Sache so langsam näher: die roten Zeilen werden weniger.

Dennoch gibts noch Probleme:

Der Fehler lautet:
MariaDB Connector/Python requires MariaDB Connector/C >= 3.1.5, found version 3.0.3

Du hast also version 3.0.3 installiert und >=3.1.5 ist notwendig.

War halt die Version, die das (aktualisierte) System installiert hat. Was anderes krieg ich wohl nicht.
