Question

好的，我刚刚在Windows 7上使用VirtualBox创建了一个全新的Ubuntu 11.04安装（不确定这是否重要但只是一个假设）

列出我的红宝石：

aaron@aaron-VirtualBox:~$ rvm list

rvm rubies

=> ruby-1.9.2-p290 [ x86_64 ]

然后尝试安装rails gem我得到了这个：

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？

在做了Dylan所说的输出之后（为了证明这些库现已安装）：

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

Answer 1

运行rvm notes并确保使用apt-get来安装RVM告诉您的内容。它（zlib1g-devel的某些内容将是其中之一）。

对于Ubuntu，它应该是这样的：

/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

之后你可能不得不重新编译1.9.2（不是100％肯定）。

Answer 2

我发现在安装上面的软件包之后我们需要安装软件包 zlib （rvm说）。所以我们需要这样做：
    rvm pkg install zlib
之后，重新安装ruby。    rvm reinstall 1.9.3
跑    gem install rails
它将成功安装rails。

Answer 3

如果您信任RVM，则可以运行以下两个命令。这个

rvm requirements run
rvm reinstall all --force

然后gem install rails命令应该可以工作。

第一步将安装RVM所需的所有软件包。你通常不需要所有，但它试图逐包搜索。

大多数人都错过了RVM安装的这一部分

最后，看看您是否有任何依赖性要求   操作系统运行：

用户$ rvm要求

在Ubuntu中全新安装RVM不让我安装gems（zlib错误）
