Question

我只花了大约3个小时试图重新安装一个nuked Rails安装。它在尝试安装“authlogic”gem后停止工作（顺便说一句，如果有人知道如何安装它，请告诉我）。

新错误

老问题

步骤是这样的： 1.输入“sudo gem install authlogic”后的Nuke Rails 2.尝试删除〜/ .rvm，仍然无法正常工作 3.使用gem uninstall，删除所有宝石，直到gem列表中没有任何内容显示--local 4. sudo gem install rails

现在，“rails”可以工作，但只能在Rails项目之外。每当我进入rails应用程序并运行rails服务器时，我都会得到以下结果：

Could not find rake-0.9.2.2 in any of the sources

显然耙子已经消失了。但只在Rails项目中（甚至是新项目！）。 rails和rake都可以正常工作，但是如果我要转到Rails项目目录，它们都会失败。

我使用的是Mac OS 10.7.3，在使用sudo gem install authlogic之前，一切正常。

这里的困难很可能是捆绑者没有意识到所有这些宝石都消失了。尝试进入你的Rails目录并进行'bundle install';这应该会导致你的所有宝石都返回。
