I installed the plugin via pip and copied the .css file to the file system, and

extra_css:
  - stylesheets/index.css
  - stylesheets/blog.css
  - stylesheets/resume.css
  - stylesheets/academics.css
  - stylesheets/neoteroi.css

markdown_extensions:
  - attr_list
  - md_in_html
  - neoteroi.projects
  - neoteroi.timeline

::timeline::

- content: First implementation.
  icon: ':material-rocket-launch-outline:'
  sub_title: 2022-Q1
  title: Launch

::/timeline::

[timeline(./docs/gantt/timeline.yaml)]

but it throws

Haven't yet. I have no idea how to solve it. I suppose it may because of the unmatch between mkdocs version and neoteroi version? Because all the codes are same to the tutorial.
