angular - npm/Angular 问题 : Could not resolve module @angular/core

Question

重新启动计算机后，我的项目突然在运行 npm run start 时出现此错误。我卸载/重新安装了节点，删除了节点模块，重新安装了 angular-cli，多次运行 npm install，但仍然出现相同的错误。我可以看到 @angular 文件夹在那里，里面有核心文件夹。

我检查了人们遇到类似问题的线程，但没有任何帮助。关于此错误的信息似乎很少，只有一两个异常(exception)。

有没有人遇到过这个问题？

我解决了这个问题。我根本不需要碰我的包裹。由于某些奇怪的原因，我的 tsconfig.json 已损坏。我恢复了它，删除了 node_modules，删除了 package-lock.json 并运行

npm 安装
