Answer 1

According logs that provided by you, It says build script can't find Python. Electron uses node-gyp for build itself, that needs to install python and Visual Studio Build Tools.

I recommend to you install windows-build-tools on npm . It can installed by using command npm install --global windows-build-tools .

Answer 2

The reason is that your module uses node-gyp - https://github.com/nodejs/node-gyp - and node-gyp needs platform compilers. Read more about these requiremens here: https://github.com/nodejs/node-gyp

If you developer box is running Windows you can install the needed compiler:

npm install --global --production windows-build-tools
