ruby_install远程安装时出现HTTP_Response_302和404的解决办法.doc

ruby install远程安装时出现HTTP Response 302的解决办法具体过程如下：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gemupdate -system，结果Updating RubyGems.ERROR: While executinggem. (Gem:RemoteSourceException)HTTPResponse302fetching/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1.0.13、从下面这个地址下载 rubygems-update-1.3.7.gem，/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geminstall-local rubygems-update-1.3.7.gem，出现信息Successfully installed rubygems-update-1.3.71geminstalledInstalling ri documentation for rubygems-update-1.3.7.Installing RDoc documentation for rubygems-update-1.3.7.Could not find main page READMECould not find main page READMECould not find main page READMECould 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/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: $geminstallrubygems-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gemupdate -system，提示Updating RubyGemsNothing to update 这是为什么我不明白，请高手指点一下5、再执行gemupdate rails -include-dependencies，提示信息Updating installed gemsUpdating railsERROR: Error installing rails: actionpack requires rack ( 1.0.0, runtime)Gems updated: activesupport, activerecordInstalling 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rack6、执行geminstallrack -v=1.0.0Successfully installed rack-1.0.01geminstalledInstalling ri documentation for rack-1.0.0.Installing RDoc documentation for rack-1.0.0.更新成功7、再次执行gemupdate rails -include-dependencies出现信息Updating installed gemsUpdating railsSuccessfully installed rake-0.8.7Successfully installed activesupport-2.3.8Successfully installed activerecord-2.3.8Successfully installed rack-1.1.0Successfully installed actionpack-2.3.8Successfully installed actionmailer-2.3.8Successfully installed activeresource-2.3.8Successfully installed rails-2.3.8Gems updated: rake, activesupport, activerecord, rack, actionpack, actionmailer, activeresource, railsInstalling ri documentation for rake-0.8.7.Installing ri documentation for activesupport-2.3.8.Installing ri documentation for activerecord-2.3.8.Installing ri documentation for rack-1.1.0.Installing ri documentation for actionpack-2.3.8.Installing ri documentation for actionmailer-2.3.8.Installing ri documentation for activeresource-2.3.8.Installing ri documentation for rails-2.3.8.Installing RDoc documentation for rake-0.8.7.Installing RDoc documentation for activesupport-2.3.8.Installing RDoc documentation for activerecord-2.3.8.Installing RDoc documentation for rack-1.1.0.Installing RDoc documentation for actionpack-2.3.8.Installing RDoc documentation for actionmailer-2.3.8.Installing RDoc documentation for activeresource-2.3.8.Installing RDoc documentation for rails-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HTTPResponse302fetching/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gemsource -l 查看列表gemsource -a 加入新的服务器地址或者直接geminstallrubygems-update -source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-0.8.7Successfully installed activesupport-2.3.8Successfully installed activerecord-2.3.8Successfully installed rack-1.1.0Successfully installed actionpack-2.3.8Successfully in
