meder@dunross:~$ haml
bash: haml: command not found
似乎它安装了haml然后遇到了一些东西并且没有安装完整的方式。我有 rubygems 1.3.6-2 和 ruby 1.8.x。Debian 莱尼操作系统。
以前有没有人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
