Question

尝试安装Rails时出现此错误：

    Z:\AlexL\My Documents\rails>gem install rails
ERROR:  Error installing rails:
        The 'json' native gem requires installed build tools.

Please update your PATH to include build tools or download the DevKit
from 'http://rubyinstaller.org/downloads' and follow the instructions
at 'http://github.com/oneclick/rubyinstaller/wiki/Development-Kit'

Z:\AlexL\My Documents\rails>gem install rails -include-dependencies
ERROR:  Error installing rails:
        The 'json' native gem requires installed build tools.

Please update your PATH to include build tools or download the DevKit
from 'http://rubyinstaller.org/downloads' and follow the instructions

ERROR:  While executing gem ... (URI::InvalidURIError)
    bad URI(is not URI?): ?gems=ûinclude-dependencies

Z:\AlexL\My Documents\rails>rails
'rails' is not recognized as an internal or external command,
operable program or batch file.

我的Ruby版本是：

ruby 1.9.3p484

我该如何解决这个问题？我在旁边的窗户上。

您收到的错误消息明确指出：

请更新您的PATH以包含构建工具或下载DevKit 来自＆＃39; http://rubyinstaller.org/downloads＆＃39;并按照说明操作在＆＃39; http://github.com/oneclick/rubyinstaller/wiki/Development-Kit＆＃39;

所以，我的建议是你下载DevKit并按照说明进行操作。
