[Vuejs]-Node-sass failing when on ruefy:vuetify

It looks like your build is trying to use Python 3.X but your build requires Python 2.X. It’s failing specifically because it’s trying to evaluate print "string" which is no longer valid in Python 3.X. It looks to be specifically a problem with node-sass trying to build via an old version of node-gyp. If you reference Node.js: Python not found exception due to node-sass and node-gyp for what looks like the same problem you should be able to fix this issue by setting the python env explicitly for npm ex npm config set python c:\python27\python.exe. You also can work around this issue by upgrading your modules. node-gyp has used python 3.X since 5.0.5. See issue https://github.com/nodejs/node-gyp/issues/1977
