I had the same error. npm uninstall npm -g, rm -rf node_modulesdidn't help me, because when I tried I was getting Error: Cannot find module 'semver'. But I solve my problem with these steps (this will delete other global modules you may be using):
我有同样的错误。npm uninstall npm -g，rm -rf node_modules没有帮助我，因为当我尝试时，我得到了Error: Cannot find module 'semver'. 但是我通过这些步骤解决了我的问题（这将删除您可能正在使用的其他全局模块）：
sudo rm -rf /usr/local/lib/node_modulessudo rm -rf ~/.npmbrew uninstall --force nodebrew install node
sudo rm -rf /usr/local/lib/node_modulessudo rm -rf ~/.npmbrew uninstall --force nodebrew install node
Hope this will help those who are getting a similar problem.
希望这能帮助那些遇到类似问题的人。

I had this too, after running brew install yarnyesterday. At least, everything was fine up until then.
brew install yarn昨天跑步后我也有这个。至少，在那之前，一切都很好。
I ran rm -rf node_modulesand tried to reinstall, but no npmcommand was working.
我运行rm -rf node_modules并尝试重新安装，但没有任何npm命令起作用。
In the end I took the rather simple step of reinstalling Node via the official Node installer for Mac OS X.
最后，我采取了相当简单的步骤，通过 Mac OS X 的官方 Node 安装程序重新安装 Node。

Everything is fine now. Just went back to the directory, ran npm installand it's done the trick.
现在一切都很好。刚刚回到目录，运行npm install它就完成了。

Actually, it is taking the reference of previously stored modules.
实际上，它正在引用以前存储的模块。
Solution:Delete the npm-cache/npm folder in the installation directory of nodejs. In windows, it is in C:/User/Username/Appdata/Roaming/npm(or npm_cache). and try to install again.
解决方法：删除nodejs安装目录下的npm-cache/npm文件夹。在 Windows 中，它在 C:/User/Username/Appdata/Roaming/npm（或 npm_cache）中。并再次尝试安装。
Same thing to do in any OS.
在任何操作系统中都要做同样的事情。

For me, this happened after I installed yarn globally. To resolve this issue, install npm using yarn and done.
对我来说，这是在我全局安装纱线之后发生的。要解决此问题，请使用 yarn 和 done 安装 npm。

On Windows, downloading Node's MSIagain and doing a 'Repair' worked for me.
在 Windows 上，再次下载Node 的 MSI并进行“修复”对我有用。
