Help! Some templates that I download work and some don’t. Does anyone out there in Jekyll land know why? I think it must have something to do with my local computer not being set up correctly. But then why do some work and some don’t? The templates that don’t work …display this error message after I do a “jekyll serve” command C:\github\_echochalet\>cd brume C:\github\_echochalet\brume\>jekyll serve WARN: Unresolved specs during Gem::Specification.reset: eventmachine (\>= 0.12.9) jekyll-watch (~\> 2.0) rouge (\< 4, \>= 1.7) rb-inotify (\>= 0.9.7, ~\> 0.9) WARN: Clearing out unresolved specs.

FYI… I’m trying to use the “brume” template that I downloaded from [https://jekyllthemes.io/theme/brume](https://jekyllthemes.io/theme/brume) I have Jekyll version 3.8.5 installed. ---

As a rule of the thumb, whenever you have a `Gemfile`, always (have `Bundler` gem installed first) prepend your invocations with `bundle exec`. Therefore, instead of running `jekyll serve`, please run `bundle exec jekyll serve`
