node.js - mac上的pug（jade）安装，报error

问题描述

问 题

前提node事先已经安装成功：
$ node -v
v8.3.0

1.安装pug
$ npm install -g pug
结果：+ pug@2.0.0-rc.3
added 57 packages in 5.928s

2.检证pug
$ pug -v
结果：-bash: pug: command not found

3.安装pug cli
$ npm install pug-cli -g
结果：/usr/local/bin/pug -> /usr/local/lib/node_modules/pug-cli/index.js+ pug-cli@1.0.0-alpha6
added 68 packages in 4.894s

4.检证pug
$ pug -v
结果：error: unknown option `-v'

请问一下是命令行写错了还是安装步骤有问题，为什么不能检证成功？

解决方案

$ pug --version
pug version: 2.0.0-rc.3
pug-cli version: 1.0.0-alpha6
