Requirements

We recommend using Bundler to install and run Jekyll. Bundler manages Ruby gem dependencies, reduces Jekyll build errors, and prevents environment-related bugs. To install Bundler, you must install Ruby.

1. ターミナルターミナルGit Bashターミナル を開いてください。

2. Check whether you have Ruby 2.1.0 or higher installed:

   $ ruby --version
   > ruby 2.X.X

3. If you don't have Ruby installed, install Ruby 2.1.0 or higher.

4. Install Bundler:

   $ gem install bundler
   # Installs the Bundler gem

5. If you already have a local repository for your Jekyll site, skip to Step 2.

Step 1: Create a local repository for your Jekyll site

1. If you haven't already downloaded Git, install it. For more information, see "Set up Git."

2. ターミナルターミナルGit Bashターミナル を開いてください。

3. On your local computer, initialize a new Git repository for your Jekyll site:

   $ git init JEKYLL-SITE-REPOSITORY-NAME
   > Initialized empty Git repository in /Users/octocat/my-site/.git/
   # Creates a new file directory on your local computer, initialized as a Git repository

4. Change directories to the new repository you created:

   $ cd JEKYLL-SITE-REPOSITORY-NAME
   # Changes the working directory

5. If your new local repository is for a Project pages site, create a new gh-pages branch:

   Note: You can skip this step if you would rather use the master branch for your Project Page. If you haven't checked out any branches, once you make a commit in your local repository, your change will appear on the master branch by default.

   $ git checkout -b gh-pages
   > Switched to a new branch 'gh-pages'
   # Creates a new branch called 'gh-pages', and checks it out

   Tip: To learn more about creating a User, Organization or Project Page and which branch to use, see "User, Organization, and Project Pages." To learn more about how to build your site's source files from a /docs folder on the master branch, see "Configuring a publishing source for GitHub Pages."

Step 2: Install Jekyll using Bundler

To track your site's dependencies, Ruby will use the contents of your Gemfile to build your Jekyll site.

1. Check to see if you have a Gemfile in your local Jekyll site repository:

   $ ls
   > Gemfile

   If you have a Gemfile, skip to step 4. If you don't have a Gemfile, skip to step 2.

2. If you don't have a Gemfile, open your favorite text editor, such as Atom, and add these lines to a new file:

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

3. Name the file Gemfile and save it to the root directory of your local Jekyll site repository. Skip to step 5 to install Jekyll.

4. If you already have a Gemfile, open your favorite text editor, such as Atom, and add these lines to your Gemfile:

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

5. Install Jekyll and other dependencies from the GitHub Enterprise Pages gem:

   $ bundle install
   > Fetching gem metadata from https://rubygems.org/............
   > Fetching version metadata from https://rubygems.org/...
   > Fetching dependency metadata from https://rubygems.org/..
   > Resolving dependencies...

   Tip: If you see a Ruby error when you try to install Jekyll using Bundler, you may need to use a package manager, such as RVM or Homebrew, to manage your Ruby installation. For more information, see Jekyll's troubleshooting page.

Step 3 (optional): Generate Jekyll site files

To build your Jekyll site locally, preview your site changes, and troubleshoot build errors, you must have Jekyll site files on your local computer. You may already have Jekyll site files on your local computer if you cloned a Jekyll site repository. If you don't have a Jekyll site downloaded, you can generate Jekyll site files for a basic Jekyll template site in your local repository.

If you want to use an existing Jekyll site repository on GitHub as the starting template for your Jekyll site, fork and clone the Jekyll site repository on GitHub to your local computer. For more information, see "Fork a repo."

1. If you don't already have a Jekyll site on your local computer, create a Jekyll template site in a new directory:

   $ bundle exec jekyll _3.3.0_ new NEW-JEKYLL-SITE-REPOSITORY-NAME
   > New jekyll site installed in /Users/octocat/NEW-JEKYLL-SITE-REPOSITORY-NAME.

2. Navigate into your new site directory:

   $ cd NEW-JEKYLL-SITE-REPOSITORY-NAME

3. Edit your Gemfile and remove the following line:

   $ "jekyll", "3.3.0"

4. In the Gemfile, delete the # at the beginning of this line:

   $ gem "github-pages", group: :jekyll_plugins

5. Initialize your site directory as a Git repository.

   $ git init
   > Initialized empty Git repository in /Users/octocat/name-of-your-directory

6. Connect your remote repository on GitHub Enterprise to your local repository for your GitHub Pages site.

   $ git remote add origin https://github.com/username-or-organization-name/your-remote-repository-name

7. To edit the Jekyll template site, open your new Jekyll site files in a text editor. Make your changes and save them in the text editor. You can preview these changes locally on your computer without committing your changes using Git by running a Jekyll command to build your site.

8. Add or stage your changes.

   $ git add .

9. Commit your changes with a comment.

   $ git commit -m "updated site"

10. To publish your changes on your GitHub Pages site, push your changes to your remote repository on GitHub Enterprise.

    $ git push -u origin master

For more information on using this Git workflow, see "Good Resources for Learning Git and GitHub Enterprise" or see this Git cheat sheet.

Step 4: Build your local Jekyll site

1. Navigate into the root directory of your local Jekyll site repository.

2. Run your Jekyll site locally:

   $ bundle exec jekyll serve
   > Configuration file: /Users/octocat/my-site/_config.yml
   >            Source: /Users/octocat/my-site
   >       Destination: /Users/octocat/my-site/_site
   > Incremental build: disabled. Enable with --incremental
   >      Generating...
   >                    done in 0.309 seconds.
   > Auto-regeneration: enabled for '/Users/octocat/my-site'
   > Configuration file: /Users/octocat/my-site/_config.yml
   >    Server address: http://127.0.0.1:4000/
   >  Server running... press ctrl-c to stop.

3. Preview your local Jekyll site in your web browser at http://localhost:4000.

Keeping your site up to date with the GitHub Pages gem

Jekyll is an active open source project and is updated frequently. As the GitHub Enterprise Pages server is updated, the software on your computer may become out of date, resulting in your site appearing different locally from how it looks when published on 使用している GitHub Enterprise Serverインスタンス.

1. ターミナルターミナルGit Bashターミナル を開いてください。

2. Run this update command:

   • If you followed our setup recommendations and installed Bundler, run bundle update github-pages or simply bundle update and all your gems will update to the latest versions.
   • If you don't have Bundler installed, run gem update github-pages

Next steps: Configuring Jekyll

To configure your pages site further, see "Configuring Jekyll." To set up a project pages site, see Jekyll's official documentation on project pages URLs.
