导入其他模块时找不到模块@angular/core

Question

我已经为此苦恼了将近 10 个小时，但无法解决。

我创建了一个新的 Angular 项目，当我服务时运行良好，但是一旦我安装并尝试导入材料模块，编译器就会开始抛出错误

错误 TS2307：找不到模块“@angular/core”。

当我从我的应用模块中删除导入语句时，此错误消失

我已经尝试重新安装节点、@angular/cli 和所有的包，但它不起作用。

如果有帮助，package.json 有

我记得 angular cdk 引起的类似情况，你可以试试下面的命令吗？

npm install --save @angular/material @angular/cdk
rm -rf node_modules
npm install
