I set up the project with vue-cli, and the iview ui, I use in order to be compatible with ie uses babel-polyfill,. Under normal circumstances, there is no problem.
but because the company needs to use single sign-on, after I introduce the public single sign-on js, I will report an error
error message as shown in the following figure.

because this js is the company"s public js, there is no way to modify it, and then this thing must also be compatible with ie,. After searching the Internet for a long time, I did not find a corresponding solution. I would like to ask you Daniel, how should I deal with this situation? is there any good way to prevent this problem, or is there any reliable plug-in that can replace babel-polyfill
