I tried typing in rake db:migrate to create a migration, but my rake is aborted and giving me this statement. Could you please explain why this is happening?

your mysql package not install properly for that give command
sudo apt-get install mysql-server mysql-common mysql-client
if this is not work install this
sudo apt-get install libmysql-ruby libmysqlclient-dev
From your question I see you are on a Macintosh. Therefore, try the following:
Run mysql_install_db in the terminal
Run mysql.server start in the terminal
If that doesn't work checkout Installing mysql2 gem for Ruby on Rails with Mac OSX 10.6

I had to mannualy install mysql2 gem because the gemfile specifies the version '0.3.20'
I ran
gem install mysql2 -v '0.3.20' -- --srcdir=/usr/local/include/mysql
Bundle install runs fine, and says everything is installed.
bundle list mysql2 evaluates to:
/Users/vitorqueiroz/.rbenv/versions/2.3.6/lib/ruby/gems/2.3.0/gems/mysql2-0.3.20

Any alternatives?
You can try
bundle exec rake db:create
to be sure that bundled gems are loaded.

I'm new to Ruby on Rails and am having trouble setting up my first MySQL database.
I followed the instructions on here: https://gorails.com/setup/osx/10.12-sierra
And I reached the very end where it asks you to run "rake db:create". When I execute this in the terminal, I get the following error:
MacBook-Air-de-myusername% rake db:create
rake aborted!

Can anyone advise on what is happening? I know that I have "cd"-ed into the correct directory, so that can't be it.
Install bundler gem and run bundle install:
$ gem install bundler
$ bundle install
Now run rake again:
$ rake db:create
If that doesn't work, then run the complete command:
$ bundle exec rake db:create
To understand more about bundle command, check this question.
Run:
gem install bundler
bundle install
bundle exec rake db:create
I think you are in incorrect folder.
try cd splash
then run following command:
bundle install
bundle exec rake db:create

How do I solve this issue?
Any help is appreciated..
Since you are using windows, you have two options to solve this :
Either use 2.8.1 version of mysql gem by writing
gem 'mysql', '2.8.1' #in your gemfile
run
bundle install
OR
Simply use mysql2 gem
gem 'mysql2'
and put the libmysql.dll file in installed MySQL bin directory with the one which you can get from the below link in location lib/libmysql.dll from
http://dev.mysql.com/get/Downloads/Connector-C/mysql-connector-c-noinstall-6.0.2-win32.zip/from/pick
gem 'mysql2' ## gemfile
rm Gemfile.lock
bundle install
rake db:drop && rake db:create

What else should I try before reinstall Lion?
Look into using Ruby Version Manager (called rvm) and then update Ruby. Try using ver 1.9 of ruby or higher. Don't reinstall your OS. If anything, remove rails, remove ruby. Install rvm, install ruby 1.9, install rails. If you follow that recipe, all should be well.
Configuring Rails to work with MySQL will happen through changing the file:
myappname/config/database.yml
Good information is here: How do I set MySQL as the default database in Rails 3?
... and here: Create a new Ruby on Rails application using MySQL instead of SQLite
Get used to looking at the Rails guides. Examples like this: http://guides.rubyonrails.org/getting_started.html#configuring-a-database are all you need to get going.
I have installed rails and mysql. I have also installed mysql2 gem. I created a rails application by the command
rails new try_cms -d mysql
It was created successfully. But when I try to run the WEBrick server using rails server command I get the following errors.

Thanks in advance.
Try running this (see similar question here)
sudo install_name_tool -change libmysqlclient.16.dylib /usr/local/mysql/lib/libmysqlclient.16.dylib /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle
Just ran into this problem myself. Make sure you update the version numbers.
sudo install_name_tool -change libmysqlclient.18.dylib /usr/local/mysql/lib/libmysqlclient.18.dylib /Library/Ruby/Gems/1.8/gems/mysql2-0.2.7/lib/mysql2/mysql2.bundle
For some reason the mysql2.bundle file was not in my mysql2 gem. I ran
gem uninstall mysql2
and the gem was uninstalled. Then I immediately ran
sudo gem install mysql2
Then
sudo install_name_tool -change libmysqlclient.16.dylib /usr/local/mysql/lib/libmysqlclient.16.dylib /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle
Finally rails s launched the server!
I had similar problems. The solutio that worked for me was found here.
If you want something a little less intrusive, just set the DYLD_LIBRARY_PATH environment variable in your MySQL's lib direction.
export DYLD_LIBRARY_PATH=$MYSQL_HOME/lib
I was just hit with this using Rails 3.1.0, ruby-1.9.2-p290 and mysql2 0.3.7. My solution was to downgrade to mysql 2.8.1. Everything looks good so far (I wasn't even able to start the environment).
sudo apt-get install libmysqlclient15-dev libmysqlclient15off libmysql-ruby
