Angular 使ng服务角度为4时出错（缺少模块）

我试图使用ng serve在浏览器中打开我的项目，但每次我运行该命令时，都会出现以下错误

ERROR in ./node_modules/@angular/platform-browser/esm5/animations.js

我很确定模块已经安装，我自己检查了路径，找到了所有表示找不到的文件，尝试卸载并再次安装，仍然是相同的问题，有人告诉我这里出了什么问题

我正在使用命令npm install@angular进行安装/animations@latest--save

我解决了我的问题，@angular/animations文件夹是空的，所以我将备份@angular文件夹中丢失的文件复制到其中，现在它工作正常。

您使用的是angular 4还是5？因为你的标题是4，但你的命令将安装最新版本的动画，即5.2.75.2.7，我检查了package.json，它说平台浏览器和动画是5.2.7，但angular是5.0.0。它不工作，这就是为什么我发布一个问题-谢谢你的大力支持-你用CLI命令生成应用程序了吗？你能和我们分享你的angular cli和tsconfig文件吗？似乎有一个错误的配置
