Run `bundle install` to install missing gems.
After bundle install Jekyll still complain missing minima-1.1.0 gem
As seen on Jekyll's home page, you have to do another bundle install from inside your site root.
gem install jekyll bundler
jekyll new my-awesome-site

Whenever I run the bundle exec jekyll serve it returns the error
Dependency Error: Yikes! It looks like you don't have kramdown-parser-gfm or one of its dependencies installed. In order to use Jekyll as currently configured, you'll need to install this gem. The full error message from Ruby is: 'cannot load such file -- kramdown-parser-gfm' If you run into trouble, you can find helpful resources at https://jekyllrb.com/help/!
Liquid Exception: kramdown-parser-gfm in /_layouts/default.html
ERROR: YOUR SITE COULD NOT BE BUILT:
------------------------------------
kramdown-parser-gfm
so, I tried gem install kramdown-parser-gfm, but it returns the same error after that.
I also tried to remove and reinstall the jekyll and bundle, but didn't work either.
jekyll version 3.9.0 Bundler version 2.1.4
I added gem "kramdown-parser-gfm" to the Gemfile and then ran bundle install.
Now the serve command completes successfully.
delete the Gemfile.lock file
go to gem file add gem "kramdown-parser-gfm"
open terminal and give command bundler
after install all packages, in terminal give command bundle exec jekyll serve
I hope application will run properly now.
On Windows
If you open your gemfile, you will notice the following.
gem "jekyll", "~> 3.2.1"
If you have the specific jekyll version and after running "bundler", you will receive the following errors.
Bundler could not find compatible versions for gem "kramdown":
In Gemfile:
jekyll (~> 3.2.1) was resolved to 3.2.1, which depends on
kramdown (~> 1.3)
kramdown-parser-gfm was resolved to 1.1.0, which depends on
kramdown (~> 2.0)
Remove the specific version of jekyll, like so:
gem "jekyll"
Do not forget to add webrick gem to gemfile
gem "webrick"
Run bundler again.
bundler
Finally, serve
bundle exec jekyll serve --livereload
What worked for me was to add:
gem "rexml"
to the Gemfile.

Probably not a problem because I want a different theme anyway. So I update it, and I also make the changes suggested in Guide steps 8 & 9.

And I can't get past this. The best I can do is remove all my gem packages and restart, which just leads me back here.
An alternative would be to "use Jekyll in Windows with Docker" (from James Sturtevant)
That would take advantage of the Docker image jekyll/jekyll (see its README).
export JEKYLL_VERSION=3.8
docker run --rm \
--volume="$PWD:/srv/jekyll" \
-it jekyll/jekyll:$JEKYLL_VERSION \
jekyll build
And you don't have to install ruby or wrestle with missing dependencies.

I've included both Ruby and the DevKit in my PATH environment variable, i.e. C:\Ruby22-x64\bin;C:\Ruby-DevKit\bin. What could be going wrong?
The command I'm running is bundle install in the ..\tindermation\node_modules\.bin directory of this project: https://github.com/feelobot/tindermation
I didn't initialize and bind the ruby installations in my DevKit to my PATH:
Downloaded it, ran it to extract it somewhere (permanent). Then cd to it, run ruby dk.rb init and ruby dk.rb install. The bundle install command worked after following these steps.
Trying to execute jekyll on cygwin (x64) on Windows when I get this error in spite of using bundle exec prefix.
Shouldn’t the dependency defined in the Gemfile (i.e. 1.8.6) be activated when executing?
Any thoughts on what is going wrong here? I am totally new to the world of Ruby gems. I have looked at other "You have already activated .. " posts showing similar messages but the answers there didn’t solve my problem.

I don't know what the issue is still, but I trimmed down the Gemfile to this and it doesn't fall in a heap. Maybe it somehow works when those particular version dependencies are not enforced.

This issue with bundler and system gems is highlighted at Gem Versioning and Bundler - Doing it right
Bundler's sandbox relies on its ability to be present at the very beginning of the Ruby process, and to therefore have the ability to ensure that the versions of all loaded libraries will reflect the ones listed in the Gemfile.lock. By running a system executable, you are executing Ruby code before Bundler can modify the load path and replace the normal Rubygems loading mechanism, allowing arbitrary unmanaged gems to get loaded into memory. Once that happens, all bets are off.
This is what seems to be happening in this situation.
But, as mentioned above - can't uninstall the system json 2.0.2 gem.
A bit late to the game, but hey, I have a solution! this is how I did it: so besides looking in your standard place where gems are installed, there is one other place where gems can apparently be "defined", and brought into the system. I install stuff using rbenv (I recommend this over RVM), and these are the directories for me:
/home/jf/.rbenv/versions/2.4.2/lib/ruby/gems/2.4.0/gems
/home/jf/.rbenv/versions/2.4.2/lib/ruby/gems/2.4.0/specifications/default
In your case, your exact location/s might be different, but you should be able to figure it out. If a gem is in the standard place (/home/jf/.rbenv/versions/2.4.2/lib/ruby/gems/2.4.0/gems), you would be able to 'gem uninstall' without a problem. For the other location, though... tough. To simply prevent the system version from being recognized so that you can use the version from the Gemfile, simply move the json-X.gemspec file away from that second directory (/home/jf/.rbenv/versions/2.4.2/lib/ruby/gems/2.4.0/specifications/default above) somewhere else. And that's it!
I had the same problem yesterday. I am not an expert but the following worked for me:
I created a new website with Jekyll using:
$ jekyll new "name_site"
I then copied the new GemFile and GemFile.lock from the new folder to the older (where you have a problem). Then, you run:
$ jekyll serve
in the folder of your current website and it should work. Let me know if it works for you!
$ gem install jekyll
$ jekyll new my-awesome-site
New jekyll site installed in /home/root/blog/Jekyll/my-awesome-site.
Dependency Error: Yikes! It looks like you don't have bundler or one of its dependencies installed. In order to use Jekyll as currently configured, you'll need to install this gem. The full error message from Ruby is: 'cannot load such file -- bundler' If you run into trouble, you can find helpful resources at http://jekyllrb.com/help/!
jekyll 3.3.1 | Error: bundler
Like you can read in documentation, you've missed bundler in gem install jekyll bundler.
So : gem install bundler and everything will be ok.
