Windows环境安装Ruby+RubyGem+DevKit+Jekyll

1.安装Ruby

下载Rubyinstall安装包https://rubyinstaller.org/downloads/，选择对应版本安装

eDaHbhG9kb

配置环境变量
1. 添加环境变量：RUBY_HOME
1. 修改path环境变量，添加地址：
2. 测试ruby是否安装成功

2.安装RubyGem

一般情况下，安装完RubyInstall后，gem已经安装完毕。

如果安装失败，可以下载rubygem自行安装https://rubygems.org/pages/download

Or, to upgrade to the latest RubyGems:

$ gem update --system          # may need to be administrator or root

NOTE: RubyGems 1.1 and 1.2 have problems upgrading when there is no rubygems-update installed. You will need to use the following instructions if you see Nothing to update. If you have an older version of RubyGems installed, then you can still do it in two steps:

$ gem install rubygems-update  # again, might need to be admin/root
$ update_rubygems              # ... here too

If you don’t have any RubyGems installed, there is still the pre-gem approach to getting software, doing it manually:

Download from above
Unpack into a directory and cd there
Install with: ruby setup.rb (you may need admin/root privilege)

For more details and other options, see:

ruby setup.rb --help

3.安装DevKit

于Ruby网站下载Devkit

运行解压后，安装DevKit：

D:\DevKit>ruby dk.rb init
[INFO] found RubyInstaller v2.5.0 at D:/Ruby25-x64

Initialization complete! Please review and modify the auto-generated
'config.yml' file to ensure it contains the root directories to all
of the installed Rubies you want enhanced by the DevKit.

根据提示可能需要修改config.yml里面ruby的根目录

修改完毕后可以回顾安装信息

D:\DevKit>ruby dk.rb review
Based upon the settings in the 'config.yml' file generated
from running 'ruby dk.rb init' and any of your customizations,
DevKit functionality will be injected into the following Rubies
when you run 'ruby dk.rb install'.

最后安装DevKit

D:\DevKit>ruby dk.rb install
[INFO] Skipping existing gem override for 'D:/Ruby25-x64'
[WARN] Skipping existing DevKit helper library for 'D:/Ruby25-x64'

配置DevKit环境变量
1. 配置DEVKIT_HOME
1. 添加Path路径

4.安装Jekyll
