我很难将Angular 2项目更新为Angular4。我正在按照https://update.angular.io/中的步骤进行操作。事情似乎起作用，但是当我运行APP时，出现Uncaught TypeError：无法读取vendor.js文件中未定义的属性'SharedStylesHost'。
当我运行以下命令npm install @angular/{animations,common,compiler,compiler-cli,core,forms,http,platform-browser,platform-browser-dynamic,platform-server,router}@^4.1.0 typescript@'>=2.1.0 <2.4.0'
然后我运行此命令npx webpack --config webpack.config.vendor.js，该命令将构建vendor.js文件
我已经尝试过，删除node_modules目录和程序包锁定文件，然后进行npm安装，但是不起作用。
这是我的package.json文件
