twitter-plugin | IntelliJ IDE plugin that helps post code to Twitter | Plugin library

I am trying to embed my twitter timeline on my Jekyll Blog hosted on Github.

This is the plugin I am trying to install: https://github.com/rob-murray/jekyll-twitter-plugin

These are instructions I am using to install plugins in general: https://jekyllrb.com/docs/plugins/

The site above includes the warning:

You can still use GitHub Pages to publish your site, but you’ll need to convert the site locally and push the generated static files to your GitHub repository instead of the Jekyll source files."

However, I get the following error when I place the example {% twitter https://twitter.com/jekyllrb maxwidth=500 limit=5 %} into my index.md file. When I do jekyll serve --watch locally, it gives the error:
