rubygems - 通过 ruby​​gems 安装 haml/sass

Question

meder@dunross:~$ sudo gem install haml
Successfully installed haml-3.0.12
1 gem installed

meder@dunross:~$ haml
bash: haml: command not found

看起来它安装了haml然后遇到了一些东西并且没有安装完整的方式。我有 ruby​​gems 1.3.6-2 和 ruby​​ 1.8.x。 Debian Lenny 操作系统。

有没有人以前遇到过这个问题或知道它可能是什么？

额外的信息:

meder@dunross:~$ gem list

*** LOCAL GEMS ***

haml (3.0.12, 3.0.9)
maruku (0.6.0)
syntax (1.0.0)
yard (0.5.8)
meder@dunross:~$ gem list haml

*** LOCAL GEMS ***

haml (3.0.12, 3.0.9)

更新 #1:我意识到我安装了 2 个版本的haml，所以我把它们都去掉了:

meder@dunross:~$ sudo gem uninstall haml

Select gem to uninstall:
 1. haml-3.0.9
 2. haml-3.0.12
 3. All versions
> 3

meder@dunross:~$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/games

可能是 $PATH 的事情，因为它没有选择 ruby​​gems 目录

Answer 1

好的。我在 $PATH 后面加上了 :/var/lib/gems/1.8/bin这似乎奏效了。
