Start by reproducing npm start in the reported Windows 10, Node v4.5.0 and npm 2.15.9 environment. The log points to the server:dev script, but contains no underlying failure output, so inspect that command's output and the package scripts before choosing a fix. Done means npm start completes successfully on the supported environment.
