Angular编译器中的错误需要TypeScript> = 3.6.4和< 3.8.0，但是找到了3.8.2 [英] ERROR in The Angular Compiler requires TypeScript >=3.6.4 and <3.8.0 but 3.8.2 was found instead

问题描述

我跑了

ng version

并获得以下输出:

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

@angular-devkit/architect         0.803.25

webpack                           4.39.2

如果我尝试将类型脚本设置得较低，则会抱怨该项目是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.

If I try set the type script lower it complains the project is Angular 9 and can't use that type of type script. Not sure what to do, any help welcomed, thanks.

推荐答案

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

Use the version which set ng update command: npm install typescript@3.7.5
