Confirming that I had this issue as well when trying to incorporate this through uglifier in the rails asset pipeline. Had to turn off compression to get it to work.

@zhuyinjing, could you please give me more information about this issue? Without a bigger description it's difficult for me to tell what the problem could be. If you have an example repo in github that you can share, that could help.

Hello, I met the same problem. How did you solve it?

Confirming that I had this issue as well when trying to incorporate this through uglifier in the rails asset pipeline. Had to turn off compression to get it to work. How to run the source code? I encountered the same problem as the theme. I couldn't use the compressed version. so try your method.
