when I change my jekyll version to “~> 4.2.1”,my jekyll project reports the error on console.

D:/Ruby27-x64/lib/ruby/gems/2.7.0/gems/liquid-4.0.3/lib/liquid/document.rb:23:in `unknown_tag': Liquid syntax error (line 112): Unknown tag 'gist' (Liquid::SyntaxError)

did you do bundle install after upgrading jekyll? are you using bundler?

is jekyll-gist installed?
