Answer 1

对我有用：

npm install typescript@3.5.3
npm install  @angular/compiler@8.2.3
npm install ajv@^6.1

npm uninstall @angular/platform-browser-dynamic
npm install @angular/platform-browser-dynamic

Answer 2

尝试升级@ angular / cli，@ angular / compiler和@ angular / compiler-cli。

npm i --save-dev @angular/cli @angular-devkit/build-angular @angular/compiler @angular/compiler-cli

npm安装后ng serve无法运行
