未能在Windows上安装Jekyll gem原生扩展，并使用“多个目标模式” [英] Failing to install Jekyll gem native extension on Windows with "multiple target patterns"
问题描述
我试图让Jekyll在我的Windows 7机器上运行，但安装gem失败并出现异常。我基本上遵循由Madhur Arhuja提供的说明加上一些修复，由于一些看似错误的链接。以下是我所做的：
I'm trying to get Jekyll up and running on my Windows 7 machine, but installing the gem fails with a make exception. I'm basically following the instructions provided by Madhur Arhuja plus some "fixes" due to some seemingly wrong links. Here is what I did:
从同一页面下载并提取RubyDevelopmentKit。
Downloaded and extracted the RubyDevelopmentKit from the same page.
在我的Git Bash从我安装开发工具包的目录中运行
In my Git Bash from the directory where I installed the development kit I ran
ruby dk.rb init
ruby dk.rb install
gem install jekyll
前两步很好。我有一些信息输出，没有错误。但最后一步创造了这个：
The first two steps worked fine. I got some Info output, no errors. But the last step created this:
$ gem install jekyll
Fetching: liquid-2.5.1.gem (100%)
Fetching: fast-stemmer-1.0.2.gem (100%)
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...

在非常简单的应用程序失败，出现多个目标模式来自Eclipse 我发现这可能与unix模拟器有关，所以我在windows shell中再次运行最后一个命令，但结果相同。
In Very simple application fails with "multiple target patterns" from Eclipse I found that this might be related to the unix emulator, so I ran the last command again in the windows shell, but with the same result.
因为我不知道有关ruby，c，make或任何涉及到的东西，我完全被卡住了： - （
Since I have no idea about ruby, c, make or anything involved I'm completely stuck :-(
推荐答案
在这行（及其后面）的Makefile定义了 .mo
Ok just a try. The Makefile on this line (and following) defines the target for .m.o.
$(Q) $(CC) $(INCFLAGS) $(CPPFLAGS) $(CFLAGS) $(COUTFLAG)$@ -c $<
如果你使用mingw / cygwin，一切看起来都不错，但如果你安装了ruby，INCFLAGS 可以在窗口机器上产生问题一个带空格的目录
INCFLAG被定义为 INCFLAGS = -I。-I $（arch_hdrdir）-I $（hdrdir）/ ruby / backward -I $（hdrdir）-I $（
Everything looks ok if you're using mingw / cygwin, but INCFLAGS can make problems on window machines, if you've installed ruby in a directory with spaces.
INCFLAG is defined as INCFLAGS = -I. -I$(arch_hdrdir) -I$(hdrdir)/ruby/backward -I$(hdrdir) -I$(srcdir) and if you see my definition below there is no space in any path.
topdir = /C/Ruby200-x64/include/ruby-2.0.0
hdrdir = $(topdir)
arch_hdrdir = C:/Ruby200-x64/include/ruby-2.0.0/x64-mingw32
如果我将ruby安装更改为具有空格的路径，我在本机窗口命令行和mingw会话中获得了无效选项错误。也许这可能会有所帮助。
If I change the ruby installation to a path with spaces I get invalid option error in native windows command line and in the mingw session. Maybe this is could help.
