我在做一个“捆绑安装”时遇到确切的错误信息。现在你需要单独安装一个旧版本的“eventmachine”。输入“gem install eventmachine -v 0.12.8”。它为我成功安装。

@ user662539：那么，我确实有“eventmachine（0.12.8）”安装成功，但我仍然无法启动瘦服务器。我收到了一条错误消息，提示“此应用程序启动失败，因为找不到msvcrt-ruby18.dll。重新安装应用程序可能会解决此问题。”。即使我复制了 “的msvcrt-ruby18.dll” 从 “\ Ruby187 \ BIN” 到 “\ Ruby192 \ BIN”，我得到了关于 “分割故障” 另一条错误消息。

所以我恢复我的红宝石版本回到红宝石1.8.7（2011-02-18 patchlevel 334）[i386-mingw32]并能够启动瘦服务器。

对不起，我无法在这一个帮助你，但这些我的新发现。
