我的项目目前是 5.2 版本，并且想升级到 Angular 7.2.15 版本，如何以最简单和最快的方式进行操作，请按照我的依赖项 package.json

  }

您可以看到它与 angular 5 和一些与 ng2 的依赖关系-...但是我认为您可以悄悄地更新每个库

我只是想知道从升级到7.2.15版本的角度我可能会改变什么，因为我认为这是不要过多破坏依赖关系的最佳时机

您需要按照角度指南从 5 更新到 7。不幸的是，没有简单的方法可以一次更新所有包。在 CLI 中，您可以使用ng update --packages <list of packages separated by space>

看看ng update。但是，您的 package.json 中的一些 ng2-... 包仍然可能需要您注意，因为它们一两年都没有更新。希望他们会支持 Angular 7，但如果不支持，请准备好用其他软件包替换它们。

使用官网的指南：https ://update.angular.io/

提示：确保从 5 更新到 6，然后再更新到 7。强烈不建议直接从 5 更新到 7。
