Hi all,

I got the error installing the npm karma. Here is a snap shot of the error log:

I have tried to open the directory as said above, but I did not find the karma folder under the nodejs-->node_modules.
Any idea why this happens?

After several trials, I found out that this is because I did not install VC++ tools when installing visual studio 2015. Just install the files below, then all is working out.
