在Windows上安装starling

我正在尝试在我的Windows机器上安装starling gem.但是,每当我尝试安装它时,我都会收到此错误:

Building native extensions.  This could take a while...  
ERROR:  Error installing starling:

我需要安装什么来提供windows.h标题？

目前Windows上的 Gems 在某种程度上被破坏了,但是现在已经修复了.以下解决方法适用于旧的One-Click Installer版本的Ruby; 你应该真正更新到新的基于MinGW的RubyInstaller和解决方法仍然适用的DevKit,但更具有未来性.

找到具有win32二进制文件的问题gem的版本(在本例中为eventmachine).如果你看看RubyForge,你会发现拥有win32二进制文件的最后一个eventmachine gem是版本0.12.0

强制安装该版本的事件机器:

$ gem install eventmachine --version=0.12.0
Successfully installed eventmachine-0.12.0-x86-mswin32
1 gem installed
Installing ri documentation for eventmachine-0.12.0-x86-mswin32...
Installing RDoc documentation for eventmachine-0.12.0-x86-mswin32...

现在安装尝试再次安装原始gem:

$ gem install starling
Successfully installed ZenTest-3.10.0
Successfully installed memcache-client-1.5.0
Successfully installed SyslogLogger-1.4.0
Successfully installed starling-0.9.8
4 gems installed
Installing ri documentation for ZenTest-3.10.0...
Installing ri documentation for memcache-client-1.5.0...
Installing ri documentation for SyslogLogger-1.4.0...
Installing ri documentation for starling-0.9.8...

Installing RDoc documentation for memcache-client-1.5.0...
Installing RDoc documentation for SyslogLogger-1.4.0...
Installing RDoc documentation for starling-0.9.8...

但请注意,如果您现在运行gem updategems将愚蠢地尝试安装最新版本的eventmachine,正如我们已经知道的那样,它不会在Windows上构建.这会导致gem更新完全停止.看到这个问题,找出如何解决这个特殊的烦恼.
