I am not even able to uninstall npm and reinstall it as I am getting the same error when I try to uninstall. What is the issue here and how do I fix it?
我什至无法卸载 npm 并重新安装它，因为我在尝试卸载时遇到了同样的错误。这里有什么问题，我该如何解决？

The reason for the error was probably conflicting global packages and node versions. I uninstalled node and npm and then reinstalled them.
错误的原因可能是全局包和节点版本冲突。我卸载了 node 和 npm，然后重新安装了它们。
To remove nodejs and associated packages (like npm):
删除 nodejs 和相关的包（如 npm）：
sudo apt-get purge --auto-remove nodejs
Nodejs and npm will leave files in the system which may cause issues during reinstallation. I had to remove them as well.
Nodejs 和 npm 会在系统中留下文件，这可能会导致重新安装时出现问题。我也不得不删除它们。
Although it is a bad practice to remove packages manually (it may cause problems with the package manager), it helped my case. Thisanswer shows how to remove nodejs and related files manually.
尽管手动删除包是一种不好的做法（这可能会导致包管理器出现问题），但它对我的情况有所帮助。此答案显示了如何手动删除 nodejs 和相关文件。
To reinstall them:
要重新安装它们：
sudo apt-get update
sudo apt-get install nodejs
sudo apt-get install npm

I got into this situation with an old version of the nnode version switcher (~v2), having switched onto Node v12. I was able to fix it by switching to a much older version of Node it had installed using n, v8 worked for me, and then upgrade the version switcher with sudo npm install -g n.
我使用旧版本的n节点版本切换器 (~v2)进入这种情况，切换到节点 v12。我能够通过切换到n使用sudo npm install -g n.
From there I could switch to any version of node and use npm again.
从那里我可以切换到任何版本的节点并再次使用 npm。

So I have recently faced a very similar problem when I was trying to run a react project in my Windows 10 x64 PC. Although I installed Node.js v12.13.0 (+ npm v6.12.0) x64; I couldn't execute npm installcommand, as it would give me this same error (Cannot read property 'resolve' of undefined).
因此，当我尝试在 Windows 10 x64 PC 中运行 React 项目时，我最近遇到了一个非常相似的问题。虽然我安装了 Node.js v12.13.0 (+ npm v6.12.0) x64；我无法执行npm install命令，因为它会给我同样的错误 ( Cannot read property 'resolve' of undefined)。
Then according to this comment, I uninstalled the x64 version of Node.js and then installed the x86 version. After this, I could execute the npm installcommand successfully.
然后根据这个评论，我卸载了x64版本的Node.js，然后安装了x86版本。在此之后，我可以npm install成功执行命令。

The problem may occur if you are using node version manager(nvm) try uninstalling it , i had the same issue and i uninstalled nvm and tried it .
如果您使用节点版本管理器（nvm）尝试卸载它，则可能会出现问题，我遇到了同样的问题，我卸载了 nvm 并尝试了它。
Worked with all versions of node . (worked fine with node 10.15.3,10.16 and 12.7)
适用于所有版本的 node 。（适用于节点 10.15.3、10.16 和 12.7）

The same issue occurred for me on FreeBSD after I tried to update a really outdated node installation.
在我尝试更新一个真正过时的节点安装后，我在 FreeBSD 上发生了同样的问题。
After removing node and npm packages (pkg delete node8-8.16.2) I had to manually remove /usr/local/lib/node_modulesdirectory (some npm dependencies had been left behind and that caused the problem).
删除 node 和 npm 包 ( pkg delete node8-8.16.2) 后，我必须手动删除/usr/local/lib/node_modules目录（一些 npm 依赖项已被留下，这导致了问题）。

Anyone having this issue and have scrolled this far, if you are installing node manually and you have nvminstalled then this might be the issue, don't do it manually, and don't uninstall nvm to fix the issue, just let nvm install the version for you rather than doing it manually, if you don't have nvm installed and you are lost trying upgrading/downgrading node/npm versions, then install nvmand let it handle all these things for you.
任何遇到此问题并已滚动到这里的人，如果您手动安装节点并且已经nvm安装，那么这可能是问题所在，不要手动执行此操作，也不要卸载 nvm 来解决问题，只需让 nvm 安装如果您没有安装 nvm 并且在尝试升级/降级 node/npm 版本时迷失了方向，请安装nvm并让它为您处理所有这些事情。
Use nvm install x.x.x, then nvm use x.x.x, and everything worked just fine.
使用nvm install x.x.x, then nvm use x.x.x，一切正常。
