Is gemfile lock necessary?

[eric3zhao]

I find "jekyll (3.1.1)" is writtern in the file Gemfile.lock.Is that means the jekyll version must be 3.1.1?I get the newest version(jekyll 3.1.2).so when I run your project,there are many errors.

# azi @ zhaowanzideMacBook-Pro in ~/minimal-theme on git:master x [16:49:24] 
$ jekyll serve
Could not find proper version of jekyll (3.1.1) in any of the sources
Run `bundle install` to install missing gems.

# azi @ zhaowanzideMacBook-Pro in ~/minimal-theme on git:master x [16:49:34] 
$ bundler install
Could not find rb-inotify-0.9.5 in any of the sources

Feel free to remove Gemfile and Gemfile.lock. Personally I would keep them and use Bundler. Running vanilla jekyll serve isn't necessarily the best way.

And yes. The versions in the .lock file are the ones that will be used. You have to run bundle update to bump them to newer versions. After they install you should run Jekyll with bundle exec jekyll serve instead. The gem versions in the Gemfile will be loaded instead of what random ones might be installed on your system which helps to mitigate conflicts.
