1.Jekyll简介
Jekyll 是一个简单的博客形态的静态站点生产机器。它有一个模版目录，其中包含原始文本格式的文档，通过 Markdown （或者 Textile） 以及 Liquid 转化成一个完整的可发布的静态网站，你可以发布在任何你喜爱的服务器上。Jekyll 也可以运行在 GitHub Page 上，也就是说，你可以使用 GitHub 的服务来搭建你的项目页面、博客或者网站，而且是完全免费的。
2.安装Jekyll
安装 Jekyll首先需要Ruby环境的支持，部分Mac自带，没有则需要安装
2.1.安装Rvm
Rvm是一个命令行工具，可以提供一个便捷的多版本 Ruby 环境的管理和切换
在控制台输入以下命令，然后回车：
$ curl -sSL https://get.rvm.io | bash -s stable
控制台输出如下：
Downloading https://github.com/rvm/rvm/archive/1.29.7.tar.gz
Downloading https://github.com/rvm/rvm/releases/download/1.29.7/1.29.7.tar.gz.asc
Found PGP signature at: 'https://github.com/rvm/rvm/releases/download/1.29.7/1.29.7.tar.gz.asc',
but no GPG software exists to validate it, skipping.

in all your open shell windows, in rare cases you need to reopen all shell windows.
切换Ruby镜像地址：
$ gem sources --remove https://rubygems.org/
$ gem sources --add https://gems.ruby-china.com/
$ gem sources -l
2.2.安装Ruby
列出可安装的版本信息（此处安装的是2.6.0）：
$ rvm list known
安装一个ruby版本：
$ rvm install 2.6.0
如果想设置为默认版本，可以用这条命令来完成：
$ rvm use 2.4.0 —default
也可执行安装命令的时候直接设置为默认版本：
$ rvm install 2.6 —default
若提示以下信息,则是缺失软件包的管理器，需要安装Command-Line Tools：
No binary rubies available for: osx/10.13/x86_64/ruby-2.6.0.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
touch: /tmp/.com.apple.dt.CommandLineTools.installondemand.in-progress: Permission denied
rm: /tmp/.com.apple.dt.CommandLineTools.installondemand.in-progress: Permission denied
执行以下命令来安装Command-Line Tools：
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
静静等待，控制台输出以下信息则是安装成功：

再次执行Ruby安装命令：
$ rvm install 2.6 —default
控制台输出以下信息则是安装成功：

2.3.安装Jekyll
通过上面的步骤，基础环境搭建好了，开始安装Jekyll，输入以下命令：
$ gem install jekyll
控制台输出如下：

安装成功后，查看版本号：
$ jekyll -v

3.Jekyll常用命令
Jekyll安装好后，就可以在命令行中使用Jekyll命令了，有以下用法:
$ jekyll build
# => 当前文件夹中的内容将会生成到 ./site 文件夹中
$ jekyll build --destination <destination>
# => 当前文件夹中的内容将会生成到目标文件夹<destination>中
$ jekyll build --source <source> --destination <destination>
# => 指定源文件夹<source>中的内容将会生成到目标文件夹<destination>中
$ jekyll build --watch
# => 当前文件夹中的内容将会生成到 ./site 文件夹中，
# 查看改变，并且自动再生成
build的时候如遇以下错误，则是缺少依赖插件包：
Dependency Error: Yikes! It looks like you don't have jekyll-paginate or one of its dependencies installed. In order to use Jekyll as currently configured, you'll need to install this gem. The full error message from Ruby is: 'cannot load such file -- jekyll-paginate' If you run into trouble, you can find helpful resources at https://jekyllrb.com/help/!
jekyll 3.8.5 | Error: jekyll-paginate
输入以下命令安装：
$ gem install jekyll-paginate
Jekyll 同时也集成了一个开发用的服务器，可以让你使用浏览器在本地进行预览。
$ jekyll serve
# => 一个开发服务器将会运行在 http://localhost:4000/
$ jekyll serve --detach
# => 功能和`jekyll serve`命令相同，但是会脱离终端在后台运行。
# 如果你想关闭服务器，可以使用`kill -9 1234`命令，"1234" 是进程号（PID）
# 如果你找不到进程号，那么就用`ps aux | grep jekyll`命令来查看，然后关闭
$ jekyll serve --watch
# => 和`jekyll serve`相同，但是会查看变更并且自动再生成
还有一些可以配置的配置选项.很多配置选项既可以在命令行中作为标识(flags)设定，也可以在源文件根目录中的 _config.yml 文件中进行设定。Jekyll 会自动加载这些配置。比如你在你的 _config.yml 文件中添加了下面几行：
destination: _deploy
source: _source
那么就等价于执行了以下两条命令：
$ jekyll build
$ jekyll build --source _source --destination _deploy
详细配置见官网配置列表：https://www.jekyll.com.cn/docs/configuration/
