当我在Git Bash上运行Jekyll服务时，我收到以下警告：
Please add the following to your Gemfile to avoid polling for changes:
gem 'wdm', '>= 0.1.0' if Gem.win_platform?
添加Gemfile后，我收到另一条错误消息。
Could not find gem 'wdm (>= 0.1.0) x64-mingw32' in any of the gem sources
listed in your Gemfile or available on this machine.
我尝试安装Ruby Devkit来解决此问题但我最终只收到以下错误消息。
$ ruby dk.rb install
[INFO] Skipping existing gem override for 'C:/Ruby200-x64'
[WARN] Skipping existing DevKit helper library for 'C:/Ruby200-x64'
$ gem install json --platform=ruby
ERROR: Error installing json:
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'

您之前似乎已经安装了devkit，它会跳过新安装，请尝试
ruby dk.rb install --force

在将bundle install gem添加到您的Gemfile中以下载之后，您需要运行wdm。
