Unknown tag 'picture' (Liquid::SyntaxError)

[ishengtsai]

Hi,

I have a really naive question and apologise if it's very basic. I have appeared to install the jekyll_picture_tag successfully but the command jekyll serve did not recognise the picture tag. What could I have done wrong please? Any suggestions would be appreciated.

My gem file:
source 'https://rubygems.org'

gem 'jekyll', '4.2.0'

group :jekyll_plugins do
gem 'webrick'
gem 'jekyll-paginate'
gem 'jekyll-sitemap'
gem 'jekyll_picture_tag'
end

Bundle info:
bundle info jekyll_picture_tag

• jekyll_picture_tag (2.1.1)
  Summary: Easy responsive images for Jekyll.
  Homepage: https://github.com/rbuchberger/jekyll_picture_tag
  Documentation: https://rbuchberger.github.io/jekyll_picture_tag/
  Path: /opt/homebrew/lib/ruby/gems/3.1.0/gems/jekyll_picture_tag-2.1.1

Log output:

/opt/homebrew/lib/ruby/gems/3.1.0/gems/liquid-4.0.4/lib/liquid/document.rb:23:in `unknown_tag': Liquid syntax error (line 9): Unknown tag 'picture' (Liquid::SyntaxError)

No worries! Did you run bundle install?
