删除 node_modules 后如何解决 npm install 问题

Question

我正在尝试清理我的 react-native 项目的包，以便在基于 MacOS 的系统上进行干净的 npm 安装（我用于 Android 开发的 Windows 系统在清理包版本方面没有问题）。

我开始在 npm 安装中看到错误，抱怨不兼容的版本差异，并列出了“rook 项目”和 node_modules/ 目录中每个包的版本之间的差异。

我通过删除 package-lock.json 进行常规修复，删除 node_modules 目录并重新运行 npm install。从我的项目文件夹中。它立即提出了同样的错误投诉。问题是这样，我的项目文件夹中没有 node_modules ，因为我删除了它。并且它没有创建新的 node_modules 目录。

鉴于这个问题，我该如何调试和修复它？我想知道的问题：

1. 如何告诉 npm 告诉我它认为根项目的价值是什么（完整路径）？
2. 如何告诉 npm 告诉我它似乎看到的 node_modules 目录的完整路径在哪里？
3. 最后，我如何强制 npm 做正确的事情并专注于我的项目的附属品，而不是像看起来那样查看项目文件夹之外？

我的一些想法。我不明白为什么要在根项目和 node_modules 之间进行包 cersion 比较？

似乎 nodde 和 npm 在 MacOS 环境中做的事情与在我的 windows 系统环境中做的事情不同——我不明白这个。

这里的任何人都可以帮助我了解发生了什么以及如何解决它？

如我的描述中所述，node_modules 目录已被删除并且运行 npm install 失败并且没有创建 node_modules 目录。因此，错误消息令人困惑，因为我的项目目录中没有包（americanaradio）。

感谢您查看此内容，希望可以从中找到解决方案。

首先检查哪个库出现错误，然后尝试重新安装或更新该版本。也尝试删除节点模块。然后执行 npm install。
