我也有这个，在昨天运行brew安装纱线后。至少，在那之前一切都很好。

我运行rm -rf node_modules并尝试重新安装，但没有npm命令工作。

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。

https://nodejs.org/en/download/

现在一切都好了。回到目录，运行npm install，它就完成了。

实际上，它引用了以前存储的模块。

处理步骤: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。 并尝试重新安装。

在任何操作系统中都是一样的。

首先，你可以尝试关闭当前终端选项卡，并打开新的工作

sudo rm -rf /usr/local/bin/npm /usr/local/share/man/man1/node* ~/.npm
sudo rm -rf /usr/local/lib/node*
sudo rm -rf /usr/local/bin/node*
sudo rm -rf /usr/local/include/node*

sudo apt-get purge nodejs npm
sudo apt autoremove

然后安装node和npm

只需删除/node_modules文件夹，然后重试。,)

你可以使用npm rm来删除它。

你也可以在GitHub上检查这个问题。 更具体地说，unnistal是这样的:

Uninstalling So sad to see you go. sudo npm uninstall npm -g Or, if that fails, sudo make uninstall More Severe Uninstalling Usually, the above instructions are sufficient. That will remove npm, but leave behind anything you've installed. If you would like to remove all the packages that you have installed, then you can use the npm ls command to find them, and then npm rm to remove them. To remove cruft left behind by npm 0.x, you can use the included clean-old.sh script file. You can run it conveniently like this: npm explore npm -g -- sh scripts/clean-old.sh npm uses two configuration files, one for per-user configs, and another for global (every-user) configs. You can view them by doing: npm config get userconfig # defaults to ~/.npmrc npm config get globalconfig # defaults to /usr/local/etc/npmrc Uninstalling npm does not remove configuration files by default. You must remove them yourself manually if you want them gone. Note that this means that future npm installs will not remember the settings that you have chosen.
