I only get this error on one particular computer when I try to compile a site – any site. When I use the exact same files on a different computer, jekyll works fine. Can someone help me understand what I have done wrong with this computer setup? Liquid Exception: undefined method `includes_load_paths' for # in _layouts/default.html jekyll 3.1.6 | Error: undefined method`includes\_load\_paths’ for #Jekyll::Site:0x00555e8dec00b8 Thanks! ---

A good place to start is to ensure you’re running the same versions of everything: ``` jekyll -v ruby -v gem -v ``` If versions check out, run `jekyll build --trace` and report back. ---

Thanks for helping me. These are the outputs.

Because Jekyll is a Ruby app you might want to look into using [Bundler](http://bundler.io/). What’s likely going on for is you have different gem versions installed across your machines and that’s causing the errors. With Bundler it uses a `Gemfile` to manage all the gem dependencies which helps you keep all the versions in sync between development environments. The only change really is prepending Jekyll commands with `bundle exec`. For a better write up on this check this post [https://learn.cloudcannon.com/jekyll/gemfiles-and-the-bundler/](https://learn.cloudcannon.com/jekyll/gemfiles-and-the-bundler/) You’ll find a lot of these sorts of errors just go away. It really is the preferred way to use Jekyll. ---

Thanks so much for weighing in here. I really appreciate it. I watched the video, created a simple Gemfile and did the bundler install, but when I use bundle exec jekyll serve, it now says bundler: failed to load command: jekyll (/usr/local/bin/jekyll) LoadError: cannot load such file – /usr/share/rubygems-integration/all/gems/jekyll-3.1.6/bin/jekyll /usr/local/bin/jekyll:22:in `load' /usr/local/bin/jekyll:22:in`\’ So there must be one last thing I am failing to do… Any thoughts? ---

Try `bundle update jekyll`. Looks like you have an older version of Jekyll so updating might help. ---

I discovered that I had installed jekyll with apt-get in addition to gem, and that is where the two were causing conflict. Once I uninstalled with apt-get and left the gem version, all conflicts went away. Thanks for your assistance.
