我在使用nokogiri的gem时遇到了问题:
无法打开库'C:\Ruby187\lib\ruby\gems\1.8\gems\nokogiri-1.4.6-x86-mingw32\ext\nokogiri\libxml2.dll': 未知错误
我看到需要尝试1.5.0.beta3版本。然而,当我运行以下命令时:
C:\Users\t3en4>gem install nokogiri --pre
Fetching: nokogiri-1.5.0.beta.4.gem (100%)
ERROR: Error installing nokogiri:
The 'nokogiri' 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'
我该怎么做?
