TECH TO THE POINT

ERROR: Visual Studio (also nuget error)  The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters http://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/2156195-fix-260-character-file-name-length-limitation FIX: Not an Error! Thats the feature of the world's best IDE - This is one big flaw in the IDE that Visual Studio conflicts with the Windows Operating system. The Windows OS supports long file path by default. VS couldn't support because the earlier developers applied this restriction in whole bunch of Windows sub products. oops. So, Change your file path, move the files and minimize the path length  to a simple (<260 charecters) directory , file path.

ERROR: npm WARN engine phonegap@2.9.0rc1-0.12.0: wanted: {"node":">=0.10.0"} (current: {"node":"v0.8.20","npm":"1.2.11"})   npm  Error: ENOENT phonegap\node_modules\shelljs\package.json FIX: As you see the warning itself shows version incompatibility. This warning further down will fire few errors with installing 'package.json' and others. Fixing the version of nodejs will fix the most errors. So install new version  for nodejs or update the nodejs with nvm .   npm cache clean - will not work in this case as the Nodejs 0.10.29 doesn't show install steps in the console unless you set it up. ERROR: “‘npm’ is not recognized as an internal or external command, operable program or batch file.”   FIX: --- Restart  the system. Some times the Path doesn't take effect until a restart in windows.
