无法使用 Windows 在 rails 中安装 JSON gem [英] Cannot install JSON gem in rails using windows

问题描述

我正在进行捆绑安装，所有 gem 都可以正常工作，除了 JSON，当它到达 JSON gem 时，我收到此错误.

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.

知道是什么导致了这个错误吗?

Any idea on what could be causing this error?

推荐答案

您使用的是 Windows，因此 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 编写的部分.

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

安装它并再次尝试安装 gem - 可能使用选项 --platform=ruby.

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