This might seem stupid, but I recently tried to install SASS and followed their instructions:
这可能看起来很愚蠢，但我最近尝试安装SASS并遵循他们的指示：
$ gem install sass
$ sass --watch [...]
So I followed along:
所以我跟着：
root@server:~# gem install sass
Successfully installed sass-3.1.15
1 gem installed
Installing ri documentation for sass-3.1.15...
Installing RDoc documentation for sass-3.1.15...
root@server:~# sass
bash: sass: command not found

尽管环顾四周就像一个白痴试图找到一些简单的方法来运行像gem run sass或其他一些解决方法来使其运行，但我或多或少都不知所措。

似乎Debian / Ubuntu将ruby gems放入/var/lib/gems/1.8/bin。
So the solution (at least for Ubuntu/Debian) is:
所以解决方案（至少对于Ubuntu / Debian）是：
$ sudo -s
# echo 'PATH=/var/lib/gems/1.8/bin:$PATH' > /etc/profile.d/gemspath.sh
# chmod 0755 /etc/profile.d/gemspath.sh
...and then open a new shell session.
...然后打开一个新的shell会话。
(This is fixed in Ubuntu 11.10.)
（这在Ubuntu 11.10中已得到修复。）
