I don't know what the problem can be. I deleted my node_modules folder first and I'm trying to do an npm install from scratch.
I keep getting the following error when I try to do a clean npm install of node_modules. I sometimes get this error with karma-script-launcher and sometimes I get it with karma-chrome-launcher.
Does anyone have any idea what it could be?
