环境 macOS 10.12.2

申请 github-pages

---

源地址 https://pages.github.com

1. 创建一个仓库
   在 github 建立一个新仓库，命名为 username.github.io，用自己的用户名替换 username。note: 如果用户名不匹配，将会不起作用。

2. clone 项目 git clone https://github.com/username/username.github.io

3. 创建 hello world。cd username.github.io && echo "Hello World" > index.html

4. push 项目。git add --all && git commit -m "Initial commit" && git push -u origin master

5. 访问 http://username.github.io，就能看到刚刚创建的网站了。

搭建 jekyll 环境

---

输入 ruby --version 验证是否安装了 ruby（Mac 已经预装了）

安装 jekyll，输入 gem install jekyll

删除之前的 index.html，运行 jekyll new .，jekyll 就会自动生成一些博客的基础文件和目录。输入 jekyll serve，就可以访问了。默认地址 http://127.0.0.1:4000/。

还可以在 _config.yml 中进行一些个性化配置。

安装模板

---

如果用 jekyll 从头开始搭建一个网站就太费时间了，可以先找一个模板，然后再在上面做修改。

一些模板网站：

• http://jekyllthemes.org/
• https://mademistakes.com/work/jekyll-themes/

我现在用的是第二个网站里的 Minimal Mistakes Theme 模板。

效果图：

安装过程

将项目 clone 下来，解压放入 github-pages 项目路径。

用以下代码替换 Gemfile 里的内容：

source "https://rubygems.org"

gem "github-pages", group: :jekyll_plugins

group :jekyll_plugins do
  gem "jekyll-paginate"
  gem "jekyll-sitemap"
  gem "jekyll-gist"
  gem "jekyll-feed"
  gem "jemoji"
end

然后运行 bundle update 安装依赖。

移除以下不需要的文件或文件夹：

• .editorconfig
• .gitattributes
• .github
• /docs
• /test
• CHANGELOG.md
• minimal-mistakes-jekyll.gemspec
• README.md
• screenshot-layouts.png
• screenshot.png

最后运行 bundle exec jekyll serve 就能在本地启动服务了。访问 localhost:4000 就能看到效果。

碰到的坑，安装的时候会碰到以下错误

************************************************************************
IMPORTANT NOTICE:

Building Nokogiri with a packaged version of libxml2-2.9.4.

Team Nokogiri will keep on doing their best to provide security
updates in a timely manner, but if this is a concern for you and want
to use the system library instead; abort this installation process and
reinstall nokogiri as follows:

    gem install nokogiri -- --use-system-libraries
        [--with-xml2-config=/path/to/xml2-config]
        [--with-xslt-config=/path/to/xslt-config]

If you are using Bundler, tell it to use the option:

    bundle config build.nokogiri --use-system-libraries
    bundle install

Note, however, that nokogiri is not fully compatible with arbitrary
versions of libxml2 provided by OS/package vendors.
