我想回答我自己的问题.我的计算机的全局 npm 安装路径是错误的.

I would like to answer my own question. The global npm install path was wrong for my computer.

npm 配置获取前缀

然后我跑去把路径放在它应该放在的地方.这个问题让我很头疼.希望它可以帮助某人.

Then I ran to put the path where it should be. This problem gave me a lot of head aches. Hope it helps someone.

npm 配置设置前缀/usr/local

npm config set prefix /usr/local
