rubygems - 通过 ruby​​gems 安装 haml/sass

Question

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

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。

有人以前遇到过这个问题或者知道这可能是什么吗？

额外信息:

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，因此我将它们都删除了:

meder@dunross:~$ sudo gem uninstall haml

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

/usr/local/bin:/usr/bin:/bin:/usr/games

可能是 $PATH 的问题，因为它没有获取 ruby​​gems 目录

Answer 1

好的。我在 $PATH 后面附加了 :/var/lib/gems/1.8/bin ，这似乎成功了。
