在Ubuntu中全新安装RVM不让我安装gems(zlib错误)

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fyi)

列出我的红宝石我得到:

aaron@aaron-VirtualBox:~$ rvm list

rvm rubies

=> ruby-1.9.2-p290 [ x86_64 ]

但后来尝试安装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:~$ 

我究竟做错了什么？

编辑:
在做了Dylan说我的输出之后(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

Answer 1

运行rvm notes并确保用于apt-get安装RVM告诉您的内容.它(zlib1g-devel其中一个将是其中之一).

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

您可能必须在之后重新编译1.9.2(不是100%确定).

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
运行 gem install rails
它将成功安装rails.
