Error trying to install Karma

Question

I am trying to install Karma using the following command:

C:\Program Files\nodejs>npm install karma 

However, when I try to install Karma on my Windows 8.1 computer, I get the following error:

Answer 1

I do not think that there are no errors.

Just need to install karma-cli

 npm install -g karma-cli 

Then karma should work.

Answer 2

I had the same problem. In my case, the solution to the problem was to use the command in the right folder. I was one folder in the hierarchy below where I should have been.
