I am making a website for my girlfriend on her birthday as i cant be with her on that day. I am using So-Simple Jekyll theme for the site but its not working somehow and not opening in local host. Its throwing the following error.

$ jekyll serve --watch
WARN: Unresolved specs during Gem::Specification.reset:
  listen (~> 2.7)
WARN: Clearing out unresolved specs.
Please report a bug if this causes problems.
c:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/jekyll-2.5.1/bin/jekyll:21:in `block in <top (required)>': cannot load such file -- jekyll/version (LoadError)

If you can help me please do as i have couple of days left for her birthday. Moreover any more birthday gift suggestions are welcome. Thanks and Regards!

I met the same error, you can run Jekyll with bundled exec instead.

bundle exec jekyll build

bundle exec jekyll serve

bundle exec: Run the command in context of the bundle.

In some cases, running executables without bundle exec may work, if the executable happens to be installed in your system and does not pull in any gems that conflict with your bundle.

However, this is unreliable and is the source of considerable pain. Even if it looks like it works, it may not work in the future or on another machine.

It works for me, if you still met the error, please give more detail info.
