本地部署 GitHub Pages 环境

安装 Ruby

确保本地已经安装了 Ruby

ruby --version

需要 2.x.x 版本。

安装 Bundler

gem install bundler

安装 Jekyll

在 GitHub Pages 目录新建文件Gemfile，内容如下：

source 'https://rubygems.org'
gem 'github-pages', group: :jekyll_plugins

然后执行：

bundler install

运行Jekyll

bundle exec jekyll serve

手动安装 nokogiri

我在安装过程中，遇到安装 nokogiri 错误的提示（系统是Mac）。通过手动安装解决。

报错信息如下：

Installing nokogiri 1.8.4 with native extensions

IMPORTANT NOTICE:

Building Nokogiri with a packaged version of libxml2-2.9.8
with the following patches applied:
    - 0001-Revert-Do-not-URI-escape-in-server-side-includes.patch

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.

An error occurred while installing nokogiri (1.8.4), and Bundler cannot
continue.
Make sure that `gem install nokogiri -v '1.8.4' --source
'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  github-pages was resolved to 192, which depends on
    jekyll-mentions was resolved to 1.4.1, which depends on
      html-pipeline was resolved to 2.8.4, which depends on
        nokogiri

先安装 pkg-config

sudo gem install pkg-config -v "~> 1.1"

手动安装 nokogiri

原始安装命令是

gem install nokogiri -v '1.8.4' --source 'https://rubygems.org/'

使用不一样的命令参数--use-system-libraries，强制使用系统库。

sudo gem install nokogiri -- --use-system-libraries

继续安装

重新运行安装命令。

bundler install
