No response or blank screen when registering the button from the login point
This is the error message reported by the mobile phone:
[vue-router] Failed to resolve async component default: SyntaxError: Invalid regular expression: invalid group specifier name
[vue-router] uncaught error during route navigation:

What do you mean by? =,? <=,?!,? <! =
1. `` `? =` ``: Ask if the thing that follows is equal to this /b(?=a)/.test('bab ')
2. `` `? <=` ``: Ask whether to start with this thing /(?<=a)b/.test('ab ')
3. `` `?!` ``: Ask if the thing that follows is not this /b(?!a)/.test('bb ')
4. `` `? <! =` ``: Ask if it does not start with this thing /(?<!=a)b/.test('bb ')
