Ruby on Rails 安装指南-优快云博客

听说ruby on rails 强大好多年了。一直没有真正实践过。进来时间宽裕。禁不住诱惑。终于踏上了ruby的贼船。

首先是安装ruby了。在官网http://www.ruby-lang.org/en/上下了个1.8.6的，一键next，环境变量也不用设置就ok了。

接着安装rails。找了一大堆资料，大都介绍利用命令gem install rails 或者 gem install rails --include dependencies 进行在线安装。省事倒是省事，可这不是我想要的，依赖性太强，万一网络不畅，岂不在这一棵树上吊死。

对于在线安装，网上的资料大部分是分别下载

            activesupport.gem 
            activerecord.gem 
            actionpack.gem 
            actionmailer.gem 
            activeresource.gem

然后分别执行命令：

            gem install activesupport.gem 
            gem install activerecord.gem 
            gem install actionpack.gem 
            gem install actionmailer.gem 
            gem install activeresource.gem 
            gem install rails.gem

rails安装就只能这么麻烦吗？想起grails的安装，一路next，简直太方便了。

于是乎，在rails官网http://rubyforge.org/下载了rails-2.1.0.zip 和 rails-2.1.0.gem

然后，将二者保存到一个文件夹（ralis）。注意（rails-2.1.0.zip不需要解压）然后进入该文件夹 cd rails

运行gem install rails rails-2.1.0.gem

出现如下错误：

 

    ERROR:  While executing gem ... (RuntimeError)
    Error instaling rails:
        rails requires rake >= 0.8.1

了解到ruby 1.8.6自带的gem还是0.9.4的。(通过gem -v可以得到),而最新的gem现在已经是1.2.0了。安装最新版的rails(2.1.0)是否需要更新gem呢。

执行如下命令，跟新gem

gem update --system

输出信息如下（信息太多，去取部分）

  ............
     = Announce: RubyGems Release 1.2.0

     Release 1.2.0 adds new features and

     New features:

     .............



     -----------------------------------

      RubyGems installed the following ex
        c:/ruby/bin/gem If `gem` was installed by a previou to    remove it by hand.

           RubyGems system software updated

现在gem已经是最新的1.2.0了。

再次在运行gem install rails rails-2.1.0.gem

等待片刻，ok。信息如下

  D:\rails>gem install rails

输入rails -v

安装成功。
