[Qgis-user] error midvatten: spatiallite file

[Azzurra Lentini]

Hallo to all,
using midvatten with Qgis 2.18 when I try (with my computer mac) to  
create a spatialite it gives me this error message:

An error has occurred while executing Python code: operational error:  
no such function: spatialite_version

Do you know what can I do?

Thanks Azzurra
