nvm弄乱了我的全局模块安装位置，如何解决？

Question

我运行npm install -g pm2，但是当我运行pm2时，出现错误：

zsh：找不到命令：pm2

我检查了/usr/local/lib/node_modules，发现pm2不存在。

我运行npm list -g，发现pm2已安装在/Users/langqiu/.nvm/versions/node/v8.14.0/lib/node_modules

但是我很早以前通过运行rm -fr /Users/langqiu/.nvm/删除了nvm并删除了nvm添加到我的〜/ .bash_profile中的内容

我再次安装了nvm，然后运行以下命令，但是npm -g仍然安装在错误的位置。

我该怎么解决？

☁  ~  nvm ls
        v8.14.0
->       system
iojs -> N/A (default)
unstable -> N/A (default)
node -> stable (-> v8.14.0) (default)
stable -> 8.14 (-> v8.14.0) (default)

我做了这些，但仍然不能解决问题

☁  ~  npm config --global set prefix /usr/local
☁  ~  npm install -g pm2

每npm docs，简称为npm config --global set prefix /usr/local
