【问题描述】：

我在尝试运行 angular2 项目时出错。它发生在从带有 ubuntu 的 PC 切换到 MacOS X 之后。节点版本：7.7.4，npm 版本：4.1.2。我正在运行npm webpack-dev-server --inline --progress --watch --port 8180，然后我得到了以下信息：

刚刚将我的宠物项目更新为@angular4 并收到了类似的警告

angular/core.es5.js 5889:15-36 Critical dependency: 
the request of a dependency is an expression

改变你的 webpack.conf.js

from: /angular(\|/)core(\|/)(esm(\|/)src|src)(\|/)linker/
to:   /angular(\|/)core(\|/)@angular/
