最近在选择开源项目管理工具,最后看上了redmine 

一开始用Bitnami,可是装好之后总是不能访问redmine 

无奈之后选择InstantRails-2.0作为安装环境 

可是按照网上的帖子装的过程中总是报错 

后来才知道是因为我装的redmine 1.0.0要求的版本要比InstantRails-2.0高,而InstantRails-2.0从2007年开始就没更新过了。 

昨晚我弄了2点半,中间几次想放弃,但拗不过自己的牛脾气,最后终于升级成功,并且成功访问了redmine。 

过程是痛苦的,结果是甜蜜的。 

虽然对ror并不是很了解,但想信我的安装经历对大家多少会有些帮忙。 



具体过程如下: 

1、InstantRails-2.0安装后,在配置环境变量path中配置ruby/bin目录(如果系统中有多个RUBY,执行命令行的时候系统认的就是path中的) 

2、进入DOS命令行,执行
gem update --system,结果 

Updating RubyGems... 
ERROR:  While executing gem ... (Gem::RemoteSourceException) 
HTTP 
Response  302 fetching http://rubygems.org/yaml 

     这是因为gem的配置过低,无法进行远程更新,执行gem -v 发现是1.0.1 

3、从下面这个地址下载 rubygems-update-1.3.7.gemhttp://rubyforge.org/frs/download.php/70695/rubygems-update-1.3.7.gem 

    然后DOS命令进行该文件所在的目录,执行gem install --local rubygems-update-1.3.7.gem,出现信息 

Successfully installed rubygems-update-1.3.7 
1 gem installed 
Installing ri documentation for rubygems-update-1.3.7... 
Installing RDoc documentation for rubygems-update-1.3.7... 
Could not find main page README 
Could not find main page README 
Could not find main page README 
Could not find main page README 

  执行gem -v查看,发现并没有更新成功,Could not find main page README是什么意思我没弄明白,但是我从http://production.s3.rubygems.org/yaml上发现这么一句 

      If you have an older version of RubyGems installed, then you can still 
      do it in two steps: 
     
        $ gem install rubygems-update  # again, might need to be admin/root 
        $ update_rubygems              # ... here too 
我照着再执行 update_rubygems,接着出现的信息很多,就不帖出来,再执行gem -v,发现更新成功,已经是1.3.7了 

这一步是一切成功的源泉!!!!!! 

4、接着再执行gem update --system,提示 

Updating RubyGems 
Nothing to update 

  这是为什么我不明白,请高手指点一下 

5、再执行gem update rails --include-dependencies,提示信息 

Updating installed gems 
Updating rails 
ERROR:  Error installing rails: 
        actionpack requires rack (~> 1.0.0, runtime) 
Gems updated: activesupport, activerecord 
Installing ri documentation for activesupport-2.3.3... 
Installing ri documentation for activerecord-2.3.3... 
Installing RDoc documentation for activesupport-2.3.3... 
Installing RDoc documentation for activerecord-2.3.3... 

执行rails -v,发现还是2.0.2没有更新成功,根据actionpack requires rack (~> 1.0.0, runtime),应该是actionpack 需要1.0.0版本的rack 

6、执行gem install rack -v=1.0.0 

Successfully installed rack-1.0.0 
1 gem installed 
Installing ri documentation for rack-1.0.0... 
Installing RDoc documentation for rack-1.0.0... 

更新成功 

7、再次执行 gem update rails --include-dependencies 

出现信息 

Updating installed gems

Successfully installed activesupport-2.3.8 
Successfully installed activerecord-2.3.8

执行rails -v,发现已更新成功 



总结:rails更新有两种方式:1、联机更新;2本地更新 

联机更新过程中如果出现HTTP Response 302 fetching http://rubygems.org/yaml无法更新,有两种情况 

一是gem的版本过低,二是与服务器的连接不通 

此时可以试着加入其他服务器地址 

gem source -l  查看列表 

gem source -a http://rubygems.org 加入新的服务器地址 

或者直接gem install rubygems-update --source http://rubygems.org 

本地更新需要下载相应的gem包,版本需与要更新的rails版本对应,同时安装顺序有要求,因此gem包之间有依赖关系 

顺序从上面的显示信息中可以看出来 

Successfully installed rake-0.8.7 
Successfully installed activesupport-2.3.8 
Successfully installed activerecord-2.3.8 
Successfully installed rack-1.1.0 
Successfully installed actionpack-2.3.8 
Successfully installed actionmailer-2.3.8 
Successfully installed activeresource-2.3.8 
Successfully installed rails-2.3.8 

至于gem包的下载地址都在http://rubyforge.org/,但是有些项目的并不好找到,可以在google中直接搜索,就能找到在http中的地址。 ://rubyforge.org/
