javascript - 卸载本地软件包时什么会导致持续错误？

Question

我正在尝试使用样板代码，但在这样做之前我必须替换/删除一些本地包。由于某些原因，我尝试删除的几乎每个包都会导致错误。

特别是我正在尝试删除 babel-cli 并使用 @babel/cli 安装(与其他依赖项相同，例如预设等)。我停留在卸载阶段，花了几天时间试图解决这个问题。我在 env.variables 部分添加了相关路径，但它似乎没有帮助。

$ npm 卸载 babel-cli

Prior to this case all my attempts were resulting in an expected message that such package has been uninstalled. Now it gives out this message.

这个问题已经解决了。可能最好的解决方案是清除 package.json、package0lock.json 和节点模块并从头开始安装所有内容。最重要的部分是使用 --save 标志单独安装 node-sass。 --与许多其他情况不同，在这种情况下必须保存
