我正在尝试使 Ruby 开发环境可移植，并且在本地化 DevKit 时遇到了一些问题。它安装得很好，但是当我尝试安装需要它的 gem 时（在这种情况下，wdm）。的内容mkmf.log可以在下面找到：

红宝石安装工作正常，我不确定是什么原因造成的。所有不需要 devkit 的 gem 都可以正常工作，但 DevKit 只是不工作......

从外观上看，您要么非常接近并且已经完成了大部分工作，要么您gcc在PATH某个不是 DevKit 的地方，但我将解释整个过程，如果我打算这样做，我会怎么做. 注意：我不想，永远。=(

由于所有正在发生的事情，这个答案真的很密集。
换句话说，你必须真的想要完成这项工作。
不要指望在不了解发生了什么的情况下复制/粘贴代码和工作。

DevKit 使用绝对路径“安装”。如果你想改变它，你将不得不做一些非常肮脏的工作来让它发挥作用。

rb加载DevKit的文件实际上位于<ruby>/lib/ruby/site_ruby/devkit.rb假设<ruby>是根安装目录。所以你需要打开它。
注意：此文件在安装过程的不同部分加载。

然后假设devkit文件夹位置与您的文件夹位于同一位置ruby，例如 E:\folderA\ruby，E:\FolderA\devkit您需要将其更改为如下所示：

# enable RubyInstaller DevKit usage as a vendorable helper library
devkit_root = File.expand_path(File.join(File.dirname(__FILE__), '../../../..', 'devkit'))
msys_bin_path = File.join(devkit_root, 'bin').gsub(File::SEPARATOR, File::ALT_SEPARATOR)
mingw_bin_path = File.join(devkit_root, 'mingw', 'bin').gsub(File::SEPARATOR, File::ALT_SEPARATOR)

unless ENV['PATH'].include?(mingw_bin_path) then
  phrase = 'Temporarily enhancing PATH to include DevKit...'
  if defined?(Gem)
    Gem.ui.say(phrase) if Gem.configuration.verbose
  else
    puts phrase
  end
  puts "Prepending ENV['PATH'] to include DevKit..." if $DEBUG
  ENV['PATH'] = "#{msys_bin_path};#{mingw_bin_path};" + ENV['PATH']
end
ENV['RI_DEVKIT'] = devkit_root.gsub(File::SEPARATOR, File::ALT_SEPARATOR)
ENV['CC'] = 'gcc'
ENV['CXX'] = 'g++'
ENV['CPP'] = 'cpp'

如果位置不同，则必须更改devkit_root相对连接。
如果要确认路径存在，则可以使用realpath代替expand_path.

现在，如果所有这些看起来都相似，那么它可能与您尝试安装的 gem 中的Makefile生成有关。extconf.rb在这种情况下，你必须在 中解决这个问题，gem如果你觉得自己是慈善的，可能会打开一个 PR。但这也可能是很多其他事情出错了，所以本质上是YMMV。
