我安装了节点、npm 和咖啡脚本，当我尝试运行咖啡命令时，我得到“-bash：咖啡：找不到命令”

我不确定 $PATH 是否有问题，所有谷歌结果都表明那是我的问题。显然我是新手，我有点过火了，但我尝试添加 npm 给我的每条路径：
$path = /usr/local/share/npm/bin/coffee:/usr/local/share/npm/bin/cake:/usr/local/share/npm/lib/node_modules/coffee-script/bin/cake:/usr/local/share/npm/lib/node_modules/coffee-script/bin/coffee:node_modules/coffee-script:/usr/local/share/npm/lib/node_modules/coffee-script:/Users/asmith:/usr/local/bin/node:/usr/local/bin/npm:~/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin
人类可读：
- /usr/local/share/npm/bin/咖啡
- /usr/local/share/npm/bin/cake
- /usr/local/share/npm/lib/node_modules/coffee-script/bin/cake
- /usr/local/share/npm/lib/node_modules/coffee-script/bin/coffee
- 节点模块/咖啡脚本
- /usr/local/share/npm/lib/node_modules/coffee-script
- /用户/史密斯
- /usr/local/bin/节点

任何帮助都会很棒！
