Can anyone help me regarding this problem?

I had the same issue on Windows 7 (x64 Ultimate), after hours of search and trials, here is how I resolved it. Please follow the steps in the same exact order:

1. Install Visual Studio 2010/2012 C++ (Express or higher)
2. Install Windows SDK 7.1
3. Install "Microsoft Visual C++ 2010 Service Pack 1 Compiler Update for the Windows SDK 7.1"
4. Install GTK (C:\GTK)
5. Install Python (C:\Python27)
6. Install node.js (x86)
7. Add [node.js] to path (C:\Program Files (x86)\nodejs\;)
8. Add [python] to path (C:\Python27\;)
9. Add [GTK] to path (C:\GTK\bin;)
10. Add [WindowsSDKDir] System Variable pointing to "C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin"
11. Run "Windows SDK 7.1 Command Prompt" as Administrator
12. Set environment to x86 using "setenv /x86"
13. Change directory to "C:\Program Files (x86)\nodejs\"
14. Run "npm install -g npm"
15. Run "npm update -g npm"
16. Run "npm install -g node-gyp"
17. Run "node-gyp configure build"
18. Run "npm install jsdom"
19. Run "npm install ajax"
20. Run "npm install http-server"
21. Run "npm install jquery"
22. Run "npm install xmlhttprequest"
23. Run "npm update"

I hope this helps.
