角度4：错误TS2300：重复的标识符'PropertyKey'

Question

这是我只是简单地打开我的本地主机并希望一切运行顺利但不行的日子之一。

启动Angular 4应用到http://localhost:3000/时，我当前遇到2个错误，我不确定为什么会发生这些错误：

node_modules/typescript/lib/lib.d.ts(105,14): error TS2300: Duplicate identifier 'PropertyKey'.
typings/globals/core-js/index.d.ts(3,14): error TS2300: Duplicate identifier 'PropertyKey'.

我的Windows 10计算机当前安装有节点版本10.14.0和npm版本6.9.0。
