Angular出现“Critical dependency: the request of a dependency is an expression”的警告

问题：Angular出现“Critical dependency: the request of a dependency is an expression”的警告

WARNING in ./~/@angular/core/@angular/core.es5.js Critical dependency: the request of a dependency is an expression 图例：

解决办法：

       new webpack.ContextReplacementPlugin(
            /angular(\\|\/)core(\\|\/)(esm(\\|\/)src|src)(\\|\/)linker/,
            utils.root('./src'), {}
        ),
复制代码

改为：

        new webpack.ContextReplacementPlugin(
            /angular(\\|\/)core(\\|\/)@angular/,
            utils.root('./src'), {}
        ),
复制代码

上面的util是定制化的工具类，这个可以不用关注，只需要替代/angular(\|/)core(\|/)@angular/,就行
