尝试运行gem install时出错 [英] Error when trying to run gem install

问题描述

我试图在我的开发服务器上运行并运行。这是一个fedora14盒子。我安装了rvm，ruby 1.8.7和rubygems 1.6.2。当我尝试通过gem安装rails时， gem install rails ，出现以下错误：

 错误：加载命令：install（LoadError）
无此类文件加载 -  zlib 
错误：执行gem时...（NameError）
未初始化的常量Gem： ：Commands :: InstallCommand 
  

关于发生了什么的任何想法。我对ruby / ruby​​gems / rails 100％全新，并且我对Linux的危险程度足够了解，因此非常感谢任何帮助/建议。

在此先感谢

解决方案

运行 rvm notes 并安装它告诉你的任何内容（ zlib-devel 可能是您需要通过 yum 来安装的软件包之一。您将看到的输出将类似于此：

 ＃对于Ruby（MRI& Ree），您应该安装以下操作系统依赖关系：
 ruby​​：yum install -y gcc-c ++补丁readline readline-devel zlib zlib-devel libyaml-devel libffi-devel openssl-devel; 
 yum install -y make bzip2; 
 yum install -y iconv-devel＃注意：对于centos 5.4 final iconv-devel可能不可用:( 
  

I'm trying to get rails up and running on my development server. It's a fedora14 box. I installed rvm, ruby 1.8.7, and rubygems 1.6.2. When I try to install rails via gem, gem install rails, i get the following error:

ERROR: Loading command: install (LoadError)
    no such file to load -- zlib
ERROR: While executing gem ... (NameError)
    uninitialized constant Gem::Commands::InstallCommand

Any ideas as to what is going on. I'm 100% new to ruby/rubygems/rails and I know enough about Linux to be dangerous so any help/suggestions would be greatly appreciated.

Thanks in advance

解决方案

Run rvm notes and install whatever it tells you (zlib-devel will probably be one of the packages you'll need to install via yum). The output you'll see will be similar to this:

  # For Ruby (MRI & Ree) you should install the following OS dependencies:
  ruby: yum install -y gcc-c++ patch readline readline-devel zlib zlib-devel libyaml-devel libffi-devel openssl-devel ;
        yum install -y make bzip2 ;
        yum install -y iconv-devel # NOTE: For centos 5.4 final iconv-devel might not be available :(
