我试图用nvm运行另一个NodeJS版本，但得到这个错误:
$ nvm use v4.2.4
nvm is not compatible with the npm config "prefix" option:
currently set to "/Users/z/.npm-global"
Run `npm config delete prefix` or `nvm use --delete-prefix v4.2.4` to unset it.
我特意设置了前缀，以避免sudo npm(参见https://docs.npmjs.com/getting-started/fixing-npm-permissions)。
是否有任何方法可以使用nvm而不丢失全局安装包的前缀?

以下是我所做的工作
1- sudo su
2-root@antonio：/home/antonio# mv ~/.nvm /tmp/
3- root@antonio：/home/antonio# export NVM_DIR=“/tmp/.nvm”
4- root@antonio:/home/antonio# NVM使用——delete-prefix v17.4.0
5- ' root@antonio:/home/antonio# node -v
`

我在把我的主文件夹移动到linux上的新驱动器后遇到了这个问题。通过删除.nvm文件夹并重新安装nvm来修复
删除并重置字冠
$ npm config delete prefix
$ npm config set prefix $NVM_DIR/versions/node/v6.11.1
注意:将版本号更改为错误消息中指示的版本号。
NVM不兼容NPM配置“prefix”选项:目前 set to "/usr/local"执行"npm config delete prefix"或"nvm use " ——delete-prefix v6.11.1——silent"
@gabfiocchi在Github -“你需要覆盖nvm前缀”
I just have a idea. Use the symbolic link to solve the error and you can still use your prefix for globally installed packages. ln -s [your prefix path] [path in the '~/.nvm'] then you will have a symbolic folder in the ~/.nvm folder, but in fact, your global packages are still installed in [your prefix path]. Then the error will not show again and you can use nvm use ** normally. ps: it's worked for me on mac. pps: do not forget to set $PATH to your npm bin folder to use the globally installed packages.
下面的sh文件有助于我的案例
# nvmish.sh
unset npm_config_prefix
source $HOME/.nvm/nvm.sh
nvm use 18
以下是我所做的工作
