Ruby 未能构建本机 gem
Ruby failed to build native gem
我正在尝试使 Ruby 开发环境可移植，但我在本地化 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（在本例中，wdm）。 mkmf.log的内容如下：

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 的 gem 都能正常工作，但 DevKit 无法正常工作...
从外观上看，您要么非常接近并且已经完成了大部分工作，要么您的 PATH 中的 gcc 不是 DevKit，但我会解释整个过程，如果我要去的话，我会怎么做。 注意：我不想，永远。 =(
由于正在发生的所有事情，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。
不要期望 copy/paste 代码和事情在不了解发生了什么的情况下工作。
具有绝对路径的 DevKit "installs"。如果你想改变它，你必须做一些真正的肮脏的工作才能让它发挥作用。
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。
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 ruby 文件夹位于同一位置，例如 E:\folderA\ruby 和 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'
如果位置有任何不同，则您必须更改 devkit_root 相对连接。
如果要确认路径存在，那么可以使用realpath代替expand_path。
现在，如果所有这些看起来都很相似，那么它 可能 与 gem 中 extconf.rb 的 Makefile 一代有关正在尝试安装。在这种情况下，您必须在 gem 中解决这个问题，如果您愿意的话，也许可以打开一个 PR。但这也可能是很多其他事情出错的原因，所以本质上 YMMV.
