Let Jekyll --watch

Jekyll has a built-in auto-regeneration feature that watches your source folder for changes and then re-builds your site. The jekyll serve command has this enabled by default and you can use run jekyll build --watch to manually enable it there.

Install the wdm Gem

On Windows, you need to install one extra tool, or rather Gem, to enable this functionality. Simply run the following command from the command line.

gem install wdm

Require wdm in your Gemfile

Alternatively, if you use a Gemfile, you can check if Jekyll runs on Windows and only then install the wdm Gem.

Open the Gemfile file that is in the root of your jekyll site. Add the following line at the end of this file.

gem 'wdm', '~> 0.1.0' if Gem.win_platform?

Install working version of listen Gem

Jekyll uses the listen Gem for auto-regeneration. The listen Gem is a dependency of Jekyll. Find the version of the listen Gem installed by the Jekyll Gem.

gem list | findstr listen

Some versions of listen do not work on Windows. jekyll/jekyll-help#64 has some information on versions that worked on Windows in the past. Please refer to the Versions table to learn which versions of listen have been tested as part of this guide. To install a specific version of the listen Gem, run this command and specify one of the tested versions.

gem install listen -v 3.1.5

It is recommended to use listen version 2.7.8 or later.
