EC2 上的 ruby 安装 zlib 问题
我读过一篇类似的文章，但我没有使用 ubuntu，也没有 apt-get。
仅供参考，uname：x86_64 x86_64 x86_64 GNU/Linux
当尝试执行“gem installrails”时，我得到
[root@domU-12-31-39-07-7D-C1 ruby-1.9.2-p136]# gem install rails
ERROR: Loading command: install (LoadError)
no such file to load -- zlib
ERROR: While executing gem ... (NameError)
uninitialized constant Gem::Commands::InstallCommand
但是，当我执行“yum install zlib”时，它说已安装。
[root@domU-12-31-39-07-7D-C1 ruby-1.9.2-p136]# yum install zlib
Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
Setting up Install Process
Package zlib-1.2.3-24.6.amzn1.x86_64 already installed and latest version
Nothing to do
我尝试了 which zlib 并确认它不存在。有什么建议吗？
谢谢。
I read a similar post but I am not using ubuntu, and do not have apt-get.
fyi, uname: x86_64 x86_64 x86_64 GNU/Linux
When attempting to do "gem install rails", I get
[root@domU-12-31-39-07-7D-C1 ruby-1.9.2-p136]# gem install rails
ERROR: Loading command: install (LoadError)
no such file to load -- zlib
ERROR: While executing gem ... (NameError)
uninitialized constant Gem::Commands::InstallCommand
However, when I do "yum install zlib", it says that is installed.
[root@domU-12-31-39-07-7D-C1 ruby-1.9.2-p136]# yum install zlib
Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
Setting up Install Process
Package zlib-1.2.3-24.6.amzn1.x86_64 already installed and latest version
Nothing to do
I tryed which zlib and have confirmed it doesn't exist. Any tips?
Thanks.

I only needed a subset of his instructions which was to go into the source and:
That's it! Thanks to Lucas;)
前几天我遇到了这个问题，我的解决方案是：“切换到 REE”...它正确安装了 gems
I ran into this problem the other day, and my solution was: "switch to REE"... which correctly installed gems
我通过搜索修复了这个错误。
