Ember production build error

[wanxie]

The addon works fine in development but when build it for production, it doesn't work.

This is what created in dist/index.html.
<script type="text/javascript" data-pace-options='...'>node_modules,pace,progress,pace.js;; undefined</script>

I'm encountering the same issue, do you have any insight on how to fix this issue ?

[wanxie]

I think this can be fixed by replacing line 93 and 94 in the index.js with the following

paceScript = UglifyJS.minify(fs.readFileSync(paceScriptPath, 'utf8')).code;
addonScript = UglifyJS.minify(fs.readFileSync(addonScriptPath, 'utf8')).code;

This should be fixed by listing uglify-js with specific version as a dependency - otherwise the proposed solution breaks package for people who happen to have uglify-js^2 installed(unless an option fromString: true is also specified).
