npm install is missing modules

Question

Before I can run gulp in my project I need to run npm install. This works except on my computer, because I get the following error:

Err         


        

Answer 1

It seems that gulp need 'karma' dependencies (socket.io ,di ,log4js...) so you will have to run :

npm install karma

so just runing this command solved the problem, and all should be good, the same thing happens with grunt as well for some reasons.
