single-sign-on - 错误 TS2322：类型“BasicProfile”不可分配给类型“GoogleUser”

Question

Property 'isSignedIn' is missing in type 'BasicProfile'.

src/app/<folder>/src/app/pages/login-module/post-login.component.ts(1908,59): error TS2339: Property 'getEmail' does not exist on type 'GoogleUser'. 

src/app/<folder>/src/app/pages/login-module/post-login.component.ts(1976,64): error TS2339: Property 'getEmail' does not exist on type 'GoogleUser'. 

当我将鼠标悬停在 gapi 上时，以下是错误；

Cannot find namespace 'gapi'.ts(2503)
Public property 'authInstance' of exported class has or is using private name 'gapi'.ts(4031)

我的 tsconfig.json 有

 "types": [
      "jquery",
      "mCustomScrollbar",
      "gapi.auth2",
      "gapi",
    ],

仍然收到此错误
