Unable to install PyGObject with Thonny Shell

Question

Original report by Anonymous.

I was installing wordcloud from thonny on windows and the error occurred, then I found that download a prebuilt whl will help. But things become messier while I was trying to install PyGObject, there is no prebuilt whl for cp36 platform and the error message goes like this:

I really need some help facing this problem.

Building native packages in Windows can be a headache, even if you have C++ compiler present.

I would try getting this module via Anaconda (https://anaconda.org/conda-forge/pygobject), ie. you should install Anaconda Python distribution, use its conda tool to install pygobject and finally let Thonny use Anaconda Python as backend (Tools => Options => Interpreter (or Backend in 2.2))
