火车失事.Rails需要RubyGems> = 1.3.2

Question

更新II问题已解决,但为什么？这是有史以来最头痛的问题.我的问题解决了,但我不知道我是如何完成这项任务的.另外,以下结果毫无意义.我的.profile路径(/ usr/local/bin)与当前工作的路径(/ usr/bin /)不同.我在OSX雪豹关闭终端后突然出现了工作路径.这里发生了什么？

这是工作路径和令人困惑的.profile文件:

$ rails -v
Rails 3.0.0.beta
$ ruby -v
ruby 1.8.7 (2008-08-11 patchlevel 72) [universal-darwin10.0]
$ gem -v
1.3.6
$ whereis ruby
/usr/bin/ruby
$ whereis rails
/usr/bin/rails
$ whereis gem
/usr/bin/gem
$ which gem
/usr/bin/gem
$ which ruby
/usr/bin/ruby
$ which rails
/usr/bin/rails
$ mate ~/.profile

.profile文件:

export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH"
if [[ -s /Users/justinz/.rvm/scripts/rvm ]] ; then source /Users/justinz/.rvm/scripts/rvm ; fi

更新我注意到哪个红宝石和哪个红宝石是不同的位置

which ruby
/opt/local/bin/ruby
whereis ruby
/usr/bin/ruby

我最近升级了红宝石ruby 1.8.7 (2009-06-12 patchlevel 174) [i686-darwin10],我想我打破了铁轨.当我尝试加载rails时.我得到一个奇怪的信息.请帮忙!

您是否研究过 Ruby Version Manager 或 rvm ( http://rvm.beginrescueend.com/ )。我知道它可以在 Linux 和 Mac OS X 上运行。

基本上，它是一个管理不同版本的 ruby​​ 及其所有相关“部分”的工具。当朋友推荐我尝试时，我也遇到了类似的问题，它为我解决了问题。
