在我看来，当前的路由器版本高于我的项目。

据我了解，路由器没有安装。在这种情况下我该怎么办？

谢谢

npm install -g @angular/router在您的计算机上全局安装路由器。基本上在 Windows 上，全局安装的 npm 依赖项可以在%AppData%/npm路径上找到。如果全局安装的 npm 包具有命令行界面（如angular-cli），则可以直接从 shell 访问命令。

如果您想在本地项目中安装路由器，您可以将所需的版本“手动”添加到package.jsonJSONdependencies条目中，并从可以找到npm install的路径中调用。package.json新添加的依赖将下载node_modules到项目的.

或者，如果您不想“手动”将其添加到package.json您可以调用项目npm install @angular/router@<wishedversion>所在的路径package.json。这样路由器将被安装在node_modules并且package.json将被更新。（当然<wishedversion>应该是您需要的版本。）

但是我在依赖项中看到了@angular/router: 9.0.7. 这意味着，它已经在，package.json所以只需npm install要从路径中调用package.json来将它安装在本地node_modules。
