Npm ERR! after merge

Hi

I’ve just merged and I’m getting this error when running npm run build. Any iddeas why?

npm ERR! Darwin 15.5.0
npm ERR! argv “/usr/local/bin/node” “/usr/local/bin/npm” “run” “build”

I get the same message!
Anyone?

Please copy the error that comes before that. This doesn’t provide enough information to understand what’s broken.
