Sorry if this is a dumb question, but I’m just starting with jekyll and haven’t found a fix yet.  
When I try to switch from minima, I put the new gem in the gem file (gem “jekyll-theme-primer” right under where minima is) and change the config file to theme: jekyll-theme-primer

I run bundle update and it says everything is fine. When I try to bundle exec jekyll serve, it returns

Configuration file: C:/Users/skbat/Desktop/skb/\_config.yml

Jekyll 4.0.0 Please append `--trace` to the `serve` command  
for any additional information or backtrace.

How can I make the new theme work? Thanks!

Based on your error report, you don’t seem to have Git installed on your system.  
Technically, Git is not required for Jekyll’s core functionality. However, some plugins and extensions expect Git to be installed.  
One such plugin is `jekyll-github-metadata` which is bundled with the `github-pages` gem.

To partially workaround the limitation, ensure that you don’t put `github-pages` under the `:jekyll_plugins` group in the Gemfile and manually add the required plugin-gems and the theme-gem to both the Gemfile and config file.
