Problema QGIS Plugin Builder e PyQt5

[NicoPez]

Buon pomeriggio a tutti.

Da un po' mi sto cimentando con creare qualche plugin ad hoc per le mie esigenze e avevo scoperto Plugin Builder. Molto utile a riguardo. Ma essendo alle prime armi mi sono imbattuto in un problema nel punto che credevo fosse il più facile da superare.

Dopo aver creato la "base" diciamo e compilato i file "resources.qrc" e "ui_testplugin.ui" con pyrcc5 e pyuic5, al punto 4 della procedura "test the plugin by enabling in the QGIS plugin manager" sorgono i problemi.

Quando vado in "QGIS --> Gestisci ed installa plugin" per questo mio plugin mi dice che c'è questo problema: "Questo plugin è corrotto. No module named PyQt5"

e più precisamente:

Impossibile caricare il plugin searchparcels2 a causa di errore chiamando il metodo classFactory()

PS: il plugin che stavo cercando di creare si chiama "searchparcels2"

Dove sbaglio? Grazie a tutti in anticipo.
