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

刚刚在Arch Linux 4.13.3上遇到了这个问题，我通过简单地重新安装semver解决了这个问题:

pacman -S semver

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.

我在这里也面临同样的问题。

如果在运行brew install yarn后发生这种情况，请尝试运行yarn global add npm和voilà -已修复!

只需删除(或重命名)克隆库的semver文件夹版本: “gitClonedRepository / App / node_modules / semver”

复制“semver”文件夹 “C: \ Program Files \ nodejs \ node_modules \ npm \ node_modules \ semver”

进入应用程序的node_modules文件夹。

(如果你在Windows上，否则它必须位于/usr/local/lib/node_modules)。

在我的情况下，简单地重新运行brew install yarn解决了这个问题。
