NPM on roaming profiles

npm config edit

change all '\\files' to the local appdata folder eg

'\\files\home\maxwillmott\AppData\Roaming\npm\node_modules'
to
'C:\Users\maxwillmott\AppData\Roaming\npm\node_modules'


stuff still won't execute though (karma). create a batch file in the working directory pointing to the relavant command eg
karma.bat => 'C:\Users\maxwillmott\AppData\Roaming\npm\node_modules\karma %*'

UPDATE
You don't have to do the BAT part if you location matches the npm path in the path variable
