Can I run specific version of Jekyll

I am on Windows 10. How to run jekyll build with Jekyll 3.8.5 version?
I have it installed. I used Windows PowerShell.

jekyll 3.8.5 build 

returns “Could not find gem ‘jekyll-3.8.5 x64-mingw32’ in any of the gem sources listed in your Gemfile. (Bundler::GemNotFound)”

  1. Create a Gemfile in your project.
  2. Add the Jekyll gem to it, specify the version you want.
  3. Run bundle install
  4. Prepend all Jekyll commands with bundle exec for example bundle exec jekyll build

Found this worked:

  1. Adding gem "jekyll", "=3.8.5" inside gem
  2. bundle update Jekyll
  3. jekyll build
