I install Anacond with Python 3.7 on Win7 and then install superset but experience build geo_hash error. It said Microsft Visual C++ 14.0 required. However I did have installed it already, see the screenshot:
The error message shows:
building '_geohash' extension error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": https://visualstudio.microsoft.com/downloads/
