Rails 3.0.7

ruby​​ 1.9.2p290（2011-07-09 修订版 32553）[i686-linux]

运行时：

$rake db:migrate --trace

我收到以下错误

Answer 1

'bundle exec rake db:migrate' 在类似的情况下为我工作，但它看起来并不“正确”。

我发现“rvm 内爆”对我来说是最干净的方法（尽管可能有点矫枉过正）。升级到 OS X Lion 后，一些 gem 似乎不再安装，我的问题出现了。

rvm内爆。重新安装rvm。安装红宝石。安装导轨。捆绑安装。

rake db:migrate 再次工作，无需在其前面添加bundle exec。

旁注：我很想知道更多关于这里实际发生的事情。我认为它与正在安装的同一 gem 的不同版本有冲突？但我找不到任何指向特定方向的详细日志记录。
