【问题描述】：

我在我的 Rails3 应用程序中使用 sunspot_rails 和 sunspot gems，并按照在 https://github.com/outoftime/sunspot 上安装 sunspot 的步骤操作，我无法让我的 sunspot 服务器运行。

当我进入我的目录时，运行 bundler 然后运行 rake sunspot:solr:start 我收到以下错误

$ rake sunspot:solr:start

【解决方案1】：

我找到了http://www.garethhunt.com/2008/02/11/cygwin-died-waiting-for-dll-loading/ 并且必须执行以下操作：

关闭所有 cygwin 窗口
从 Run (Win-R) 调用 c:\cygwin\usr\bin\ash
从那里拨打rebaseall

【讨论】：

【解决方案2】：

我遇到了类似的问题（Windows 7 企业版，使用 cygwin 和 rails），发现简单的 rebaseall 方法不起作用。简而言之，问题在于 rebaseall 不一定知道它必须修复的所有 .dll 和 .so。解决方案是编写您自己的列表并使用 -T 选项对该列表运行 rebaseall。对我来说，最终奏效的过程是：

在 cygwin shell 中：find /bin /lib /usr -iname '*.so' > /tmp/to_rebase.lst
在 cygwin shell 中：find /bin /lib /usr -iname '*.dll' >> /tmp/to_rebase.lst
退出所有 cygwin shell 并停止所有 cygwin 进程
以管理员身份运行 C:\cygwin\bin\ash.exe
/bin/rebaseall -T /tmp/to_rebase.lst
退出灰
重启机器
