我收到错误消息“ [ts]找不到模块'@ angular / platform-browser / animations'。”
我已经安装了以下内容：
，然后尝试将app.module中的BrowserAnimationsModule导入，如下所示： “从'@ angular / platform-browser / animations'导入{BrowserAnimationsModule};“
这在我的package.json中

文件中的@angular依赖项未对齐。根据您的配置，package.json是@angular/animations，而所有其他^7.0.1库都设置为@angular/*。
您应该对所有^2.4.0范围内的软件包使用相同的符号。如果您决定更新，则可能必须将打字稿和其他一些库升级。

在我看来，您正在尝试将最新版本的Angular Material与过时的Angular版本结合使用。
我建议您要么坚持使用2.x.x版本的Angular Material和Angular CDK，要么按照以下步骤操作：
注1：除非明确说明，否则所有命令都应在项目的根目录中运行。
注释＃2：请不要在命令中复制注释（即#符号及其后的文本）。他们在那里解释命令的作用。
通过运行以下命令来重新安装Angular CLI，以安装最新版本：
npm i -g @angular/cli # Globally installs the Angular CLI
npm i @angular/cli # Locally installs the Angular CLI (to your project)
通过运行以下命令将Angular项目文件更新为新的Angular CLI v6 +工作区文件：
ng update @angular/cli
通过运行以下命令来安装最新版本的TypeScript（v3.1.1）：
npm i -D typescript@latest
这对于Angular v7及更高版本是必需的。
通过运行以下命令将所有Angular依赖项更新为Angular v7 +：
ng update @angular/core
应该（希望如此）！如果您需要任何说明，请随时发表评论！
注意：以上说明是根据官方Angular Update Guide改编的。
