Trying to jekyll serve in my project but I have the following issue (with the trance flag -t )

I don't even know where to start investigating from here.

Note that I'm aware and have tried this and that questions.

Answer 1

According to https://github.com/envygeeks/jekyll-assets/issues/622 This is actually a problem with sprockets 4.0.0 .

You can fix it by forcing the earlier version in your Gemfile:

gem "sprockets", "~> 3.7"

Then run

bundle install

To fetch the new gem and update your Gemfile.lock

Answer 2

This may not be enough: even with gem "sprockets", "~> 3.7" , using ruby 3.0 made it still fail so I had to downgrade to ruby 2.7.3 using rvm

$ curl -sSL https://get.rvm.io | bash
$ source ~/.rvm/scripts/rvm
$ rvm install 2.7
$ rvm use 2.7
$ bundle install
