pip install throws error - bin/sh: 1: mysql_config: not found

Il fallimento si verifica durante l’installazione della dipendenza mysqlclient, con setup.py e setup_posix.py mostrati nel traceback. Prima riproduci il comando di pattern pip install segnalato, poi esamina come la dipendenza gestisce l’assenza di mysql_config e definisci il completamento come un’installazione riuscita senza l’errore di generazione dei metadati.
