我确信它以前运行良好，没有任何问题.这是我的系统信息和package.json.

I am sure it worked well without any problems before. Here are my system information and package.json.

系统:

    Node : v8.10.0
    npm  : 5.6.0
    OS   : Windows 10

Package.json:

我猜这个问题与 @ionic/app-scripts 问题.

推荐答案

删除 @angular/cli 应该对你有用

如果不是，请将 Typescript 版本更改为 ~2.6.2.

if not, change Typescript version to ~2.6.2.

@angular/cli 1.7.3 仅适用于 Typescript ~2.6.2.

@angular/cli 1.7.3 works with Typescript ~2.6.2 only.
