我使用的是Windows系统，Ruby版本为1.9.3，安装了DevKit（在Win7 64位系统上全部是32位）。现在我尝试安装Rails，但是遇到了来自bundle的错误。如果我尝试运行（这是bundle抱怨的内容）

 gem install json

我遇到了以下错误信息：

D:\RubyTest>gem install json
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing json:
        ERROR: Failed to build gem native extension.

你可以打开在你的 Ruby 版本中找到的 "include" 目录下的 "win32.h" 文件。

然后注释掉声明 "clock_gettime" 和 "clock_getres" 函数的行。

Ruby 1.9.3是使用GCC 4.5.2编译的，该编译器是DevKitDevKit-tdm-32-4.5.2-20111229-1559-sfx.exe，可从RubyInstaller's download page下载。

您下载了新版本的DevKits，但这些版本仅与Ruby 2.0.0兼容，如RubyInstaller公告所示。

澄清一下：

Ruby 1.8.7：tdm-32-4.5.2
Ruby 1.9.2：tdm-32-4.5.2
Ruby 1.9.3：tdm-32-4.5.2
Ruby 2.0.0：mingw64-32-4.7.2（64位Ruby的64位版本）

我已经在RubyInstaller下载页面上添加了澄清说明。

希望这能帮到您。
