应用程序加载时出现以下错误。无法加载@ angular/platform-browser-dynamic

请在我的项目中找到放置config和.ts文件的文件夹结构。请验证文件是否被放置在正确的文件夹

为什么应用程序无法在node_modules下载入platform-browser-dynamic？我验证了文件存在于指定的文件夹下，仍然出现此错误。

注：尽管NPM /依赖性文件夹说，“不安装”，但我可以展开文件夹，并注意到所有的引用是否正确安装，但仍显示此错误/警告消息

有你尝试重新启动IDE？ – maxisam

多次尝试，没有用...其他建议？ – Krishnan

尝试吹走整个node_modules目录并再次运行'npm install'。如果它仍然存在，请在角色团队的github页面上提交错误报告。你的配置文件和package.json对我来说看起来很好，所以不清楚发生了什么事情，很难在不复制你的环境的情况下重现问题。 – BrianRT
