javascript - 错误 : Could not find API compiler-cli, 函数 __NGTOOLS_PRIVATE_API_2

Question

我使用 Angular 项目并收到以下错误，

    $ ng serve 
Your global Angular CLI version (8.3.21) is greater than your local
version (7.0.7). The local Angular CLI version is used.

To disable this warning use "ng config -g cli.warnings.versionMismatch false".

  Data path ".builders['app-shell']" should have required property 'class'.

提供了package.json文件，

如何解决这个问题？

这个问题可能非常明显，但是，这是我第一次开始使用 JavaScript 语言，所以对我来说不是。

Answer 1

将 package.json 从 "@angular-devkit/build-angular": "^0.900.3" 更新为 "^0.12.4"

运行npm install
