Question

我在Windows上，使用RailsInstaller安装了Ruby 2.0。

当我尝试使用gem install id3lib-ruby安装id3lib-ruby时，我得到以下内容：

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中，它包含以下行：

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zlib1.dll中有C:\RailsInstaller\Ruby2.0.0\bin，将文件重命名为zlib.dll不起作用。因此，看起来RubyInstaller已经包含了zlib库，但仍然导致gem安装失败。有什么想法吗？

无法解决问题。通过安装RailsInstaller 2.2.2（Ruby 1.9.3）和taglib-ruby来“修复”。

使用RailInstaller在Windows上安装gem：＆＃34;您必须安装zlib＆＃34;
