我继承了一个项目，并且以前的开发人员正在使用该机器，一切似乎都正常，然后开始执行新的UAT，所以我执行标准，安装了一切，项目失败了，Angular8？可能是问题所在，我到处都是关于更改的站点/论坛，@ NewChild需要2个参数，打字稿不能超过3.5，等等，我一生无法使其正常工作。

我查看了我正在使用的开发机器上的副本。一切似乎都合法了。所以我清空了UAT机器，重新开始，但是出于某种原因，我感到沮丧，我安装了core和cli ，但此后我跳过了'npm install'阶段，一切正常。

我查看了开发机上发生的情况，似乎它也从未运行过npm安装。

这怎么工作？为什么npm install会破坏事情？我可能有7或8个软件包失败，node_modules不在git repo中，并且我将该文件夹擦了三次，所以它不能是文件的旧副本。

这里有工作包。
