在'@ angular / platform-b​​rowser'ionic 4中找不到导出'DOCUMENT'

Question

尝试将IONIC应用程序从版本3升级到版本4

时发生

 ERROR in ./node_modules/ionic-angular/es2015/components/app/app.js
 export 'DOCUMENT' was not found in '@angular/platform-browser'
 ERROR in ./node_modules/ionic-angular/es2015/module.js 191:71-79
 export 'DOCUMENT' was not found in '@angular/platform-browser'

我该如何解决
