npm is not recognized as internal or external command operable program or batch file

Question

I am completely new to nodejs  I am trying to get nodejs to work on my Windows 2008 box in order to install Karma which I would use for TDDing my AngularJs code  I have done the following steps so far   Install using Chocolatey     npm is not recognised Install using 64-bit nodejs installer from nodejs org     npm is not recognised At this stage  running where npm gives me c  User  lt Username gt  AppData Roaming npm which has nothing in it I figure out that nodejs is installed in C  Program Files nodejs  Opening a command prompt in this directory makes npm work fine  So I added C  Program Files nodejs to PATH only to get the same error again that npm is not recognized One of the github issues on nodejs repository says that I need to restart the machine and it would fix  But that has not helped so far I do see a Node js icon in my Start - gt  Programms mennu which takes me to nodejs console but not sure what to do with that     Have I missed any important step in the process   Edit  I figured out that if I open  Nodejs command prompt  from program files  then npm is recognized  How do I make it work on a normal command prompt   Edit  After node I started facing a similar problem with another application  I posted this question on superuser and as rightly pointed out by the accepted answer  I had an additional quote in my PATH which was causing issues with all the paths added after the quote  I have a feeling that some Chocolatey install adds this troubling quote but I am just not sure which one
