仅供参考，我正在使用Gem 1.1.1

我也尝试过gem更新rails、gem更新rake和其他任何东西

rake aborted!
can`'t activate rake

现在是中秋节，也许落叶太多，耙子不能用了。试着改用吹叶机

下一次，继续清理以防止出现这种情况。

我遇到了一个类似的问题，我最终通过修改rails版本以不初始化活动资源（通过修改/rails/railties/builtin/rails\u info/rails/info.rb中的components方法）解决了这个问题

这显然是一个黑客行为，但我没有机会弄清楚为什么active\u资源会导致rake冲突，而且因为我没有使用active\u资源，所以我熬了一个晚上。

有趣的是，这里的解决方案是我需要降级我的rake版本。本地版本（在我的C:\ruby目录中）正在覆盖源目录中的版本，无法加载。我已经完成了gem更新，并更新了我所有的本地gem

命令是：

gem uninstall rake
gem install rake -v ('= 1.5.1')

只有在你有答案的情况下才开玩笑，否则就是垃圾。洛洛那很有趣。LOLOL的意思是我“真的”笑了出来，所以这就像LOL loud不开玩笑的回答通常会出现在问题评论中？好吧，你不必标记为没有答案，这是在评论不存在之前出现的。
