I want to add a csv-layer by PyQGIS in a standalone script. This is my code:

uri = 'file:///C:/Users/sml/Desktop/point.csv?delimiter=,&crs=epsg:4326&xField=x&yField=y'
vlayer = QgsVectorLayer(uri, "point", "delimitedtext")
print(vlayer.isValid())
QgsProject.instance().addMapLayer(vlayer)

The same code works fine in the QGIS Python console, but it can't work in a standalone script. I don't know why.

It seems your question was already asked in GIS.SE. Does this answer work for you? – Germán Carrillo Dec 29 '20 at 02:14
Thank you! That works! I didn't set my QGIS prefix path, that's the reason it didn't work. – user174852 Dec 29 '20 at 02:47
Of course! I will do that! – user174852 Dec 29 '20 at 03:41
