Uninitialized constant Liquid::Expression::MethodLiteral

Help

Hi, I followed the instructions from Quickstart | Jekyll • Simple, blog-aware, static sites, but upon issuing bundle exec jekyll serve I get the following stacktrace thrown at me:

Liquid Exception: uninitialized constant Liquid::Expression::MethodLiteral in /home/grzesiek/.local/share/gem/ruby/3.0.0/gems/minima-2.5.1/_layouts/default.html
                    ------------------------------------------------
      Jekyll 4.2.2   Please append `--trace` to the `serve` command 
                     for any additional information or backtrace.

My ruby version is ruby 3.0.3p157 (2021-11-24 revision 3fb7d2cadc) [x86_64-linux].

Could you help me resolve this issue?

I don’t think jekyll will work with liquid 5? not sure how you would get it installed though.

It kind of looks like you have ruby installed twice? once in usr/bin and again in home/ ?

If you aren’t using ruby for anything else I think I would uninstall it and re-install it and see what happens.

So I’ve repeated all the steps carefully and fixed the problem.

Previously I didn’t run gem install jekyll, so my ruby used a system-installed jekyll, which seems to have caused problems.
