在Ubuntu中RVM的全新安装不允许我安装gem (zlib错误)
好吧，我刚刚用VirtualBox在Windows7上创建了一个全新的Ubuntu11.04安装(不确定这是否重要，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 ]但是在尝试安装rails gem时，我得到了这样的结果：
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：
在按照Dylan所说的做完之后，我的输出(为了证明这些库现在已经安装)：
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并确保使用apt-get来安装RVM告诉您的内容。它(类似于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，您可能必须重新编译1.9.2 (不是100%确定)。

我发现在安装了上面的包之后，我们需要安装包rvm (说)。所以我们需要做的是：
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。

如果您信任RVM，则可以运行以下两个命令。这
rvm requirements run
rvm reinstall all --force那么gem install rails命令应该可以工作。
第一步将安装RVM所需的所有包。您通常不需要全部包，但它胜过试图逐个包搜索包。
大多数人错过了RVM安装的这一部分
最后，通过运行以下命令来查看您的操作系统是否有任何依赖项要求：
