这个n是切换哪个目录下安装的?

这个n是简写吗?全称是什么?

安装完用配置环境变量吗?要怎么配置

输入n --help出现的是一个路径

:\Users\10668>n --help

/bin/bash: C:\Users\10668\AppData\Roaming\npm\node_modules\n\bin\n: No such file or directory

C:\Users\10668>

下面是用npm的方法

npm  install n -g

npm ERR! code EBADPLATFORM

下面使用cnpm的方法

C:\Users\10668>cnpm  install n -g
