Hi I'm not able to use npm on Windows 8.1 64bit. It shows the error message as in image link. I have installed nodejs v5.7.1
ERROR MESSAGE: 'CALL "C:\Program Files\nodejs\node.exe" "C:\Program Files\nodejs\node_modules \npm\bin\npm-cli.js" prefix -g' is not recognized as an internal or external com mand, operable program or batch file. 3.6.0
Tried changing PATH variables and installing a fresh copy in a different drive also
Please help. Thanks
