使用RailInstaller在Windows上安裝gems：「您必須安裝zlib」

Question

我在Windows上，使用RailsInstaller安裝Ruby 2.0。

當我試圖安裝使用gem install id3lib-ruby id3lib，紅寶石，我得到如下：

Temporarily enhancing PATH to include DevKit... 
Building native extensions. This could take a while... 
ERROR: Error installing id3lib-ruby: 
     ERROR: Failed to build gem native extension. 

    C:/RailsInstaller/Ruby2.0.0/bin/ruby.exe extconf.rb 
checking for main() in -lstdc++... yes 
checking for main() in -lz... no You must have zlib installed. 
*** extconf.rb failed *** 
Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. 
Check the mkmf.log file for more details. 
You may need configuration options. 

在mkmf.log，它包括行：

c:/railsinstaller/devkit/mingw/bin/../lib/gcc/mingw32/4.5.2/../../../../mingw32/bin/ld.exe: cannot find -lz 
collect2: ld returned 1 exit status 

我在C:\RailsInstaller\Ruby2.0.0\binzlib1.dll，將文件重命名爲zlib.dll不起作用。所以，它看起來像RubyInstaller已經包含了zlib庫，但仍然導致gem安裝失敗。有任何想法嗎？

無法解決問題。 「固定」通過安裝RailsInstaller 2.2.2（Ruby 1.9.3）和taglib-ruby來代替。
