JSON Gem無法在Windows上構建

Question

好的，在Windows XP上使用DevKit安裝了一個非常基本的Ruby 1.9.3安裝。

當我嘗試執行rails new myapp時，它開始安裝json並死亡。

Installing json (1.7.5) with native extensions C:\devkit\bin\make.exe: *** Couldn't reserve space for cygwin's heap, Win32 error 6 

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension. 

     C:/Ruby193/bin/ruby.exe extconf.rb 
creating Makefile 

make 
     0 [main] us 0 init_cheap: VirtualAlloc pointer is null, Win32 error 487 
AllocationBase 0x0, BaseAddress 0x60E90000, RegionSize 0x170000, State 0x10000 
C:\devkit\bin\make.exe: *** Couldn't reserve space for cygwin's heap, Win32 error 6 


Gem files will remain installed in C:/Ruby193/lib/ruby/gems/1.9.1/gems/json-1.7.5 for inspection. 
Results logged to C:/Ruby193/lib/ruby/gems/1.9.1/gems/json-1.7.5/ext/json/ext/generator/gem_make.out 
An error occured while installing json (1.7.5), and Bundler cannot continue. 
Make sure that `gem install json -v '1.7.5'` succeeds before bundling. 

我試着手動安裝和幾個舊的版本，但沒有骰子。我的devkit也更新到RubyInstaller.org的最新版本，以防發生問題，但沒有運氣

我發現這個網頁：http://support.code-red-tech.com/CodeRedWiki/VirtualAllocPointerNull其中說在某些安裝中msys.dll的版本不起作用，但用附件替換掉我。
