您似乎不依赖“@angular/core”。这是一个错误

运行 Angular 4 项目时出现以下错误。

you seem to not be depending on "@angular/core". This is an error.

详细说明请参见下图：

当前版本：Angular Cli：1.7.3 Node：8.10.0

在此处输入图片描述

我尝试过这个选项：

rm -rf node_modules
rm package-lock.json
npm install

运行上述命令时出现以下错误：

我通过运行以下命令得到了解决方案：

删除你的节点模块，检查你的 package.json 文件是否包含 @angular/core 然后用它重新安装 npm i。
