我试图升级我的Angular CLI、Ionic和Cordova版本，现在我不能再运行我的Ionic服务了，当我试图取消所有版本并安装旧版时，我总是会收到一个错误，但有点不同。
现在我得到了：
Module '"C:/Users/mylaptop30/Desktop/ArbesTech-Projects/Andrian/InstantDealNew/node_modules/firebase/index"' has no exported member 'functions'.
我的版本是：Ionic@3.9.2、Cordova 8.1.2(Cordova-lib@8.1.1)、Angular 6.4.1.
在我尝试玩我的火球版本之前，我得到了：
cannot find module firebase/app
当我尝试升级我的Angular CLI时，我得到了：
Cannot redeclare block-scoped variable 'ngDevMode'
我在互联网上搜索了每一个错误的解决方案，但当我修复一个错误时，就会出现另一个错误。请帮帮我！！！

}
尝试删除node_modules文件夹，然后重新安装它们以查看错误是否消失。
rm -rf node_modules
npm install
你的错误到处都是，所以很难确定是什么原因造成的。我认为是许多不同的问题造成的，而不是一个本地化的问题。
尝试在文件夹项目上运行npm rebuild以重建插件
