I'm just new to node and npm and this is frustrating.
Well it's almost all said in the title. On a Windows 10 x64 using a NON elevated prompt, all npm commands shows:
EEXIST: file already exists, mkdir 'c:\Users\Josep\AppData\Roaming\npm'
at Error (native)
Even npm -v shows it twice before the version number.
Not hapening in an elevated prompt. version numbers differ in an elevated and a user prompt.
Double checked PATH variable. Same on two cmd windows.
Node version 6.10.0
NPM Versions: 4.3.0 at elevated prompt and 3.10.10 at a user prompt.
