ruby install相关(远程安装时出现HTTP Response 302的解决办法)
?
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.
gem，
http://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?

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/
