However, there's a few gotchas...
1) You need to install Python on your machine (in addition to Node.js) - as of writing this is version 2.7.10.
2) Your npm install may not install everything completely in one go. If you've tried running node server.js and get complaints about the weak module, it's worth manually installing it by running:
npm install weak
2.1) If you don't have Visual Studio 2010 installed, you might get the following error:
C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\Microsoft.Cpp.Platform.targets(64,5): error MSB8020: The build tools for Visual Studio 2010 (Platform Toolset = 'v100') cannot be found. To build using the v100 build tools, please install Visual Studio 2010 build tools. Alternatively, you may upgrade to the current Visual Studio tools by selecting the Project menu or right-click the solution, and then selecting "Upgrade Solution...". [C:\prerender\prerender\node_modules\weak\build\weakref.vcxproj]
You can get around this by specifying your installed version of Visual Studio:
npm install weak --msvs_version=2013
Obviously, if you have 2012 installed then replace 2013 with 2012.
That should be enough to get Prerender running without any issues locally!
