  • I think, you need to install python first.[link](http://stackoverflow.com/questions/15126050/running-python-on-windows-for-node-js-dependencies) and [link](http://stackoverflow.com/questions/9970329/npm-install-jsdom-error-on-windows) – Surjith S M Dec 23 '13 at 11:04

    Be aware of pm2 in windows. Right now is only intended to work in Linux and MacOS. Check the project in github or [this issue](https://github.com/Unitech/pm2/issues/6) – durum Dec 23 '13 at 11:13
  • You are better off developing on linux. A lot of npm modules which have non JS code (c++ mostly) aren't built to work on windows. – Munim Dec 23 '13 at 12:47

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).
