Trouble getting a specific version of Jekyll - Windows

Question

How do I switch my version of Jekyll or download a specific version of it? This is all new to me and upon following the instructions provided by https://jekyllrb.com/docs/installation/windows/ I was able to get the specific Ruby version I wanted with the RubyInstaller+DevKit but every time I use "gem install Jekyll bundler" it gives me only the most recent version of Jekyll. How would I proceed to get Jeyll version 3.8.2 for example?

I've tried to install a specifc version from the command line with gem install jekyll -v 3.8.2 and it installs but how do I switch versions now? I also tired using 3.8.2 serve --watch to switch versions but it just gives me:

Answer 1

So to install Jekyll v3.8.2 on Windows, definitely use Ruby 2.7 which looks like you have installed.

Since you already have a project, run:

gem install jekyll -v 3.8.2

Now open the Gemfile and update the line

gem "jekyll", "~> 3.8.2"

It should look like this on a fresh install:

source "https://rubygems.org"
# Hello! This is where you manage which Jekyll version is used to run.
# When you want to use a different version, change it below, save the
# file and run `bundle install`. Run Jekyll with `bundle exec`, like so:
#
#     bundle exec jekyll serve
#
# This will help ensure the proper Jekyll version is running.
# Happy Jekylling!
gem "jekyll", "~> 3.8.2"

Next is installing everything, using bundler install. If that works correctly, then its time to check if its working.

bundle exec jekyll --version
>> jekyll 3.8.2

You can also try running gem add webrick if things aren't working still. I had issues with kramdown as well, so make sure that is at 1.14
