Question

当前，我的应用程序在Angular 8中，并且我在项目中使用 @ angular-material-extensions / google-maps-autocomplete 库。

在将项目从Angular 8.1.0更新到9.0时，我使用以下命令更新了此依赖项：

ng update @angular-material-extensions/google-maps-autocomplete --allowDirty --force

在运行 ng serve 命令时，出现以下问题：

目标入口点“ @ angular-material-extensions / google-maps-autocomplete”中的错误缺少相关性：-@ angular / flex-layout

手动安装flex-layout软件包可以解决此问题。

手动安装是个好方法吗？是否应该通过更新angular-material-extensions / google-maps-autocomplete库来自动处理它？</ p>

Answer 1

试试这个，而不是npm i @ angular / flex-layout @ 9.0.0-beta.31 它为我解决了这个问题

Answer 2

如果使用ng update执行更新，它将无法将所有依赖项软件包更新到最新版本。

如果您使用ng update --all而不是ng update，它会同时更新所有对等项的依赖关系以及它们的依赖关系
