无法在使用Windows的rails中安装JSON gem [英] Cannot install JSON gem in rails using windows

问题描述

我正在做一个捆绑安装，所有的gems都能正常工作，除了JSON，当它到达JSON gem时，我收到了这个错误。

I am doing a bundle install and all of the gems work fine except JSON when it get to the JSON gem I receive this error.

Installing json (1.6.1) with native extensions c:/Ruby192/lib/ruby/site_ruby/1.9.1/rubygems/installer.rb:55
    2:in `rescue in block in build_extensions': ERROR: Failed to build gem native extension. (Gem::Installer::E
    xtensionBuildError)

            c:/Ruby192/bin/ruby.exe extconf.rb
    checking for re.h... *** extconf.rb failed ***
    Could not create Makefile due to some reason, probably lack of
    necessary libraries and/or headers.  Check the mkmf.log file for more
    details.  You may need configuration options.

任何关于可能导致此错误的想法？

Any idea on what could be causing this error?

推荐答案

您正在使用Windows，所以RubyInstaller开发工具包可以帮助您：
http://rubyinstaller.org/add-ons/devkit/

You are working with Windows, so the RubyInstaller Development Kit may help you: http://rubyinstaller.org/add-ons/devkit/

devkit安装了一个C编译器（和其他一些东西）来编译C写的部分。

The devkit installs a C-compiler (and some other stuff) to compile C-written parts.

安装它，然后再次尝试安装gem - 也许使用选项 - platform = ruby 。

Install it and try again to install the gem - perhaps with option --platform=ruby.
