我正在尝试使Ruby开发环境可移植，并且我在本地化DevKit时遇到了一些问题。它安装得很好，但是当我试图安装需要它的gem时(在本例中是wdm)。mkmf.log的含量如下:

ruby安装工作正常，我不确定是什么原因造成的。所有不需要devkit工作的宝石，但devkit只是不工作…
从事物的外观来看，您要么非常接近并且已经完成了大部分工作，或者您在PATH中有gcc，这不是DevKit，但我将解释整个过程，如果我要这样做，我会如何做到这一点。注意:我不想，永远。= (
这个答案非常密集，因为所有正在发生的事情。
换句话说，你必须真的想让它工作。
DevKit使用绝对路径"安装"。如果你想改变它，你将不得不做一些真正的肮脏的工作使它工作。
加载DevKit的rb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。
然后假设devkit文件夹位置与ruby文件夹位置相同，例如: E:folderAruby和E:FolderAdevkit你需要改变它看起来像这样:
# 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。
如果您想确认路径存在，那么您可以使用realpath而不是expand_path。
现在，如果所有这些看起来很相似，那么可能是与你试图安装的gem中的extconf.rb生成的Makefile有关。在这种情况下，你必须在gem中修复这个问题，如果你觉得慈善的话，可能会打开一个PR。但也可能是其他很多地方出了问题，所以本质上是YMMV
