您可以看到它与angular 5以及ng2有一些依赖关系-...但是我认为您可以悄悄地更新每个库的内容

我只想知道从升级到7.2.15版本可能要做些什么，因为我认为这是不破坏依赖关系的最佳时机

Answer 1

您将需要按照角度指南从5升级到7。不幸的是，没有一次简便的方法可以一次更新所有软件包。在CLI中，您可以使用ng update --packages <list of packages separated by space>

看看ng update。但是，您package.json中的某些ng2 -...软件包仍可能需要引起您的注意，因为它们在一两年之内都没有更新。希望它们将支持angular 7，但如果没有，请准备将其替换为其他软件包。

Answer 2

使用官方网站指南：https://update.angular.io/

提示：强烈建议您不要从5更新到6，然后再更新到7。强烈建议不要直接从5更新到7。
