It seems that InfluxDB Python package depends on ciso8601, which requires compilation.

It seems that running pip install ciso8601 without Visual Studio, with VS 2019 and VS 2015 all fails to compile ciso8601.

The package should have clearer instructions on how it should be installed on Windows.

Also, perhaps it is possible to not use ciso8601 and use built-in datetime features if the said package is not available? So that if ciso8601 is present, it is used, but otherwise it's still possible to use the client?

Hi @wojciechka,

we use ciso8601 to parsing timestamps in query results. It's much faster than built-in datetime.

I am going to update README with instructions how to build client on Windows platform.

Hi @wojciechka,

for successfully installation client on Win platform you should install Visual C++ Build Tools 2015: http://go.microsoft.com/fwlink/?LinkId=691126&fixForIE=.exe.

After that the ciso8601 will be builded.

Regards
