好的，我刚刚创建了一个新的Ubuntu 11.04安装在Windows 7上使用VirtualBox(不确定这是否重要，但只是供参考)
列出我得到的红宝石:
aaron@aaron-VirtualBox:~$ rvm list
rvm rubies
=> ruby-1.9.2-p290 [ x86_64 ]
，但然后试图安装rails gem我得到这个:
aaron@aaron-VirtualBox:~$ gem install rails
ERROR: Loading command: install (LoadError)
no such file to load -- zlib
ERROR: While executing gem ... (NameError)
uninitialized constant Gem::Commands::InstallCommand
aaron@aaron-VirtualBox:~$
我做错了什么?
编辑:
按照Dylan说的做了之后，我的输出(证明这些库已经安装):
aaron@aaron-VirtualBox:~$ sudo apt-get install build-essential bison openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev

运行rvm notes，并确保使用apt-get来安装RVM告诉您的东西。它(类似zlib1g-devel的东西将是其中之一)。
对于Ubuntu，应该是这样的:
/usr/bin/apt-get install build-essential bison openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev
之后您可能需要重新编译1.9.2(不是100%确定)。
我发现我们需要安装包zlib后安装以上包(rvm说)。所以我们需要做:rvm pkg install zlib
之后，重新安装ruby。rvm reinstall 1.9.3
运行gem install rails
它将成功安装rails。
如果信任RVM，可以运行以下两个命令。这个
rvm requirements run
rvm reinstall all --force
那么gem install rails命令应该可以工作了。
第一步将安装RVM所需的所有软件包。你通常不需要所有的，但是它比一个包一个包地搜索要好。
大多数人忽略了RVM安装的这一部分
最后，看看是否有任何依赖于您的操作系统:
user$ RVM requirements
