Jekyll on Windows
While Windows is not an officially-supported platform, it can be used to run Jekyll with the proper tweaks. This page aims to collect some of the general knowledge and lessons that have been unearthed by Windows users.
The easiest way to run Jekyll is by using the RubyInstaller for Windows.
Installation via RubyInstaller
RubyInstaller is a self-contained Windows-based installer that includes the Ruby language, an execution environment, important documentation, and more. We only cover RubyInstaller-2.4 and newer here, older versions need to install the Devkit manually.
- Download and Install a Ruby+Devkit version from RubyInstaller Downloads. Use default options for installation.
- Open a new command prompt window from the start menu, so that changes to the
PATHenvironment variable becomes effective. Install Jekyll and Bundler via:
gem install jekyll bundler
- Check if Jekyll installed properly:
That’s it, you’re ready to use Jekyll!
If you use UTF-8 encoding, make sure that no
BOM header characters exist in your files or very, very bad things will happen to
Jekyll. This is especially relevant when you’re running Jekyll on Windows.
Additionally, you might need to change the code page of the console window to UTF-8 in case you get a “Liquid Exception: Incompatible character encoding” error during the site generation process. It can be done with the following command:
Since Windows doesn’t have a native source of zoneinfo data, the Ruby Interpreter would not understand IANA Timezones and hence using them had the
TZ environment variable default to UTC/GMT 00:00.
Though Windows users could alternatively define their blog’s timezone by setting the key to use POSIX format of defining timezones, it wasn’t as user-friendly when it came to having the clock altered to changing DST-rules.
Jekyll now uses a rubygem to internally configure Timezone based on established IANA Timezone Database.
While ‘new’ blogs created with Jekyll v3.4 and greater, will have the following added to their
Gemfile by default, existing sites will have to update their
Gemfile (and installed) to enable development on Windows:
# Windows does not include zoneinfo files, so bundle the tzinfo-data gem gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]
Jekyll uses the
listen gem to watch for changes when the
--watch switch is specified during a build or serve. While
listen has built-in support for UNIX systems, it may require an extra gem for compatibility with Windows.
Add the following to the
Gemfile for your site if you have issues with auto-regeneration on Windows alone:
gem 'wdm', '~> 0.1.1', :install_if => Gem.win_platform?
You have to use a Ruby+Devkit version of the RubyInstaller.
Installation via Bash on Windows 10
If you are using Windows 10 version 1607 or later, another option to run Jekyll is by installing the Windows Subsystem for Linux.
Note: You must have Windows Subsystem for Linux enabled.
First let’s make sure all our packages / repositories are up to date. Open a new Command Prompt instance, and type the following:
Your Command Prompt instance should now be a Bash instance. Now we must update our repo lists and packages.
sudo apt-get update -y && sudo apt-get upgrade -y
Now we can install Ruby. To do this we will use a repository from BrightBox, which hosts optimized versions of Ruby for Ubuntu.
sudo apt-add-repository ppa:brightbox/ruby-ng sudo apt-get update sudo apt-get install ruby2.5 ruby2.5-dev build-essential dh-autoreconf
Next let’s update our Ruby gems:
sudo gem update
Now all that is left to do is install Jekyll.
sudo gem install jekyll bundler
Check if Jekyll installed properly by running:
Configure the bundler/gem path so bundle doesn’t prompt for sudo
bundle config path vendor/bundle
And that’s it!
You can make sure time management is working properly by inspecting your
_posts folder. You should see a markdown file with the current date in the filename.
Non-superuser account issues
If the `jekyll new` command prints the error "Your user account isn't allowed to install to the system RubyGems", see the "Running Jekyll as Non-Superuser" instructions in Troubleshooting.
Note: Bash on Ubuntu on Windows is still under development, so you may run into issues.
