How to tell if npm package was installed globally or locally

Question

I am installing grunt, node, npm, bower, and grunt-cli on windows7.

The instructions say i should run the install commands with -g flag for global.

How can I

Answer 1

To check if a specific package is installed globally execute:

npm list -g [package-name]

Let's take "grunt" as an example. If it is installed globally, you should see something like this

C:\data\tryout\test1>npm list -g grunt
C:\Users\xxxxxxx\AppData\Roaming\npm
└── grunt@0.4.5

If it is not installed globally, you should see something like this

C:\data\tryout\test1>npm list -g grunt
C:\Users\xxxxxxx\AppData\Roaming\npm
└── (empty)

To check if a specific package is installed locally you can execute the same commands as above but without the -g parameter.
