IE8 error after JS compression

[XPLing]

After using r.js to optimize, JS is compressed and other browsers have no problem, but there is a lack of identifiers, strings, or numbers under IE8.


Please help you, thank you.

You need to compile it without optimizer and then optimize in a custom way yourself.
Also IE8 is dead, just like IE9, IE10 and to large degree IE11. Don't expect anyone to bother with browsers that old.
