PM2 uses native components which require compilation. Many node packages utilize node-gyp (reference) to make building native C/C++ code cross platform more convenient and reliable.

One of the dependencies of node-gyp is the 2.7.3+ series of Python (3.x is not compatible). So, in order to compile a package that does not already include native binaries or a fall back to JavaScript, you may need Python. But, if you are compiling on Windows, you'll also need to have a compiler. I'd suggest following the instructions on the node-gyp web page (you'll need to install a free version of Visual Studio).

But, you'll encounter the more serious error later that PM2 isn't supported on Windows ( https://github.com/Unitech/pm2/issues/6?source=cc).
