Why did App.vue not mount successfully when using vue-cli, to open the built-in browser for Android (5.1.1)?

now the problem with the project is that in the lower version of the Android built-in browser, the page is white and there is no error, but the page can be opened normally with Wechat in the same low version of Android. So I don"t know what the reason is, it"s useless to try all kinds of mounting methods on the Internet.
originally thought that the white page was due to grammatical problems. After adapting to it and then slowly checking it out, I found that it may be the problem of unsuccessful mounting. What are the reasons why App.vue can not be mounted successfully?

Open it with a higher version of Android or a lower version of Android Wechat browser:

5.11:

Vue-cli vue.js html javascript html5

theoretically, it should not.
has encountered this situation: when the route pattern of
vue is history , the blank page opens in webview of some models. Just change
to hash mode.
