node.js - "npm install leaflet-headless" returning errors after Python installation

Question

I'm trying to run the command 'npm install leaflet-headless' so I can use the leaflet map API with Node.js easily. I just installed Python and set the directory (as this was the previous error in this particular installation), but now I am getting a new error which I can't quite decipher:

Note - I'm guessing this requires GTK, though I just have no idea how to set it for use with this specific command. All the installs seem to not be in the directory required by this command.

Answer 1

node-gyp needs python and Visual Studio installed and the path to their executables. This walkaround fixed it for me:

Uninstall the following products and then reinstall them in the order listed:

1) Visual C++ 2010 Express

2) Windows SDK 7.1

3) Visual Studio 2010 SP1

4) Visual C++ 2010 SP1 Compiler Update for the Windows SDK 7.1

Be sure that you env paths are set correctly !
