npm ERR! extraneous: 的问题

Question

本来是在更改mac下的npm全局安装路径，

npm config set prefix "path"

并export path
引入了path之后path变成了这样

/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/chengjiachen/Downloads/node-global

之后安装全局包，安装没报错，但是找不到命令
运行

npm ls -g --depth=0

之后发现一堆rt的错

192:Downloads chengjiachen$ npm ls -g --depth=0
