angular - Angular 编译器中的错误需要 TypeScript >=3.6.4 和 <3.8.0，但找到了 3.8.2

Question

我跑了

ng version

并得到以下输出:

Angular CLI: 9.0.3
Node: 12.16.1
OS: win32 x64

Angular: 9.0.2
... animations, common, compiler, compiler-cli, core, forms
... language-service, platform-browser, platform-browser-dynamic
... router
Ivy Workspace: Yes

Package                           Version

webpack                           4.39.2

如果我尝试将类型脚本设置得较低，它会提示该项目是 Angular 9 并且无法使用该类型的类型脚本。不知道该怎么办，欢迎任何帮助，谢谢。

使用设置ng update命令的版本:npm install typescript@3.7.5
