Invalid regular expression with vue.js and gulp-requirejs

[sn00pee]

similar to #4344
I get an error:

Parse error using esprima for file: /.../bower_components/vue/dist/vue.js
Error: Line 6386: Invalid regular expression
In module tree:
    src/js/main.js
      loadmore

    at /.../node_modules/gulp-requirejs/node_modules/requirejs/bin/r.js:23419:47

Line 6386:
var regexEscapeRE = /[-.*+?^${}()|[\]/\\]/g;

when using vue.js with requirejs
Doesn't happen when used with vue.min.js

Vue.js version

2.1.4

This is likely a bug in requirejs rather than Vue.js.
