How to Remove Installed npm packages globally?
提问by user1272965
I think I've been using npm incorrectly, most of the time installing globally (with -g) instead of locally (with -save). Now I have a long list of global packages that I want/ought** to clean up.
我想我一直在错误地使用 npm，大部分时间是全局安装（使用 -g）而不是本地安装（使用 -save）。现在我有一长串想要/应该**清理的全局包。
(**I'm new to this, and in addition to being OCD-tidy, I don't want to accidentally use a package in an app without explicitly mentioning it, otherwise it might become a tough puzzle to deploy someplace.).
（**我是新来的，除了 OCD 整洁之外，我不想在没有明确提及的情况下意外地在应用程序中使用包，否则在某个地方部署可能会成为一个难题。）。
I understand that I can use npm uninstall <package> -gto do the actual removal, but how do I decide what should stay?There's a looong list of things named like "[email protected]" and so on.
我知道我可以npm uninstall <package> -g用来进行实际的移除，但我如何决定应该保留什么？有一长串类似“[email protected]”之类的东西。
Is there a way to determine if a project is using it, or if its the kind of thing I need globally? It will be a long day going to the docs for each one. Or maybe there's a rule of thumb, like: "one typically needs x, y, and z, and you can delete the rest"?
有没有办法确定一个项目是否正在使用它，或者它是否是我在全球范围内需要的那种东西？为每个人查看文档将是漫长的一天。或者也许有一个经验法则，比如：“一个人通常需要 x、y 和 z，你可以删除其余的”？
Also, once I have a removal list, is my only choice to execute all of those unistall -g commands one by one?
另外，一旦我有了删除列表，我是否唯一的选择是逐一执行所有这些 unistall -g 命令？

this didn't work on ubuntu for pm2, I had to run npm remove pm2 -g
这在 ubuntu for pm2 上不起作用，我不得不运行 npm remove pm2 -g
