Testing your GitHub Pages site locally with Jekyll

In this article

You can build your GitHub Pages site locally to preview and test changes to your site.

GitHub Pages is available in public repositories with GitHub Free and GitHub Free for organizations, and in public and private repositories with GitHub Pro, GitHub Team, GitHub Enterprise Cloud, and GitHub Enterprise Server.

Anyone with read permissions for a repository can test a GitHub Pages site locally.

Prerequisites

Before you can use Jekyll to test a site, you must:

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:

  1. Install Ruby. For more information, see "Installing Ruby" in the Ruby documentation.
  2. Install Bundler. For more information, see "Bundler."

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 "Troubleshooting" in the Jekyll documentation.

Building your site locally

  1. Open TerminalTerminalGit Bash.

  2. Navigate to the publishing source for your site. For more information, see "Configuring a publishing source for your GitHub Pages site."

  3. Run bundle install.

  4. 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.

    Note: If you've installed Ruby 3.0 or later (which you may have if you installed the default version via Homebrew), you might get an error at this step. That's because these versions of Ruby no longer come with webrick installed.

    To fix the error, try running bundle add webrick, then re-running bundle exec jekyll serve.

  5. To preview your site, in your web browser, navigate to http://localhost:4000.

Updating the GitHub Pages gem

Jekyll is an active open source project that is updated frequently. If the github-pages gem on your computer is out of date with the github-pages gem on the GitHub Pages server, your site may look different when built locally than when published on GitHub Enterprise Server. To avoid this, regularly update the github-pages gem on your computer.

  1. Open TerminalTerminalGit Bash.
  2. Update the github-pages gem.
    • If you installed Bundler, run bundle update github-pages.
    • If you don't have Bundler installed, run gem update github-pages.
