Creating a bundle with webpack doesn't work

[TimPietrusky]

When you try to create a bundle with npm run bundle the following error is thrown:

ERROR in ./node_modules/node-static/lib/node-static.js
Module build failed (from ./node_modules/babel-loader/lib/index.js):
SyntaxError: /Volumes/finalspace/dev/js/luminave-fivetwelve/node_modules/node-static/lib/node-static.js: Invalid number (365:22)
