Trying to install a node module on windows (via npm) and I keep getting the annoying error message:
I have Visual Studio 2013 installed but the project requires the 2010 version. After lots of digging around I discovered an option you can pass to npm, forcing it to use whatever version of Visual Studio you like.
npm install karma --msvs_version=2013
This was a welcome relief as getting the Visual Studio 2010 build tools appears to involve a full install of Visual Studio 2010!?!
