I've been having trouble getting the mysql2 adapter working with the latest version of rails. I Just generated a new project. Added the following to my gemfile:
gem 'mysql2', '< 0.3.7'
then of course ran:
bundle install
I also modified my database.yml file:
development:
adapter: mysql2
encoding: utf8
database: blog_development
username: root
password: *********
socket: /tmp/mysql.sock
test:
adapter: mysql2
encoding: utf8
database: blog_test
username: root
password: ********
socket: /tmp/mysql.sock
production:
adapter: mysql2
encoding: utf8
database: blog_production
username: root
password: *********
socket: /tmp/mysql.sock
So when I try and run rake db:create, the following is the output.
$ rake db:create --trace
** Invoke db:create (first_time)
** Invoke db:load_config (first_time)
** Invoke rails_env (first_time)
** Execute rails_env
** Execute db:load_config
** Execute db:create
rake aborted!
Please install the mysql2 adapter: `gem install activerecord-mysql2-adapter` (can't activate mysql2 (~> 0.3.10), already activated mysql2-0.3.6. Make sure all dependencies are added to Gemfile.)

Tasks: TOP => db:create
It's telling me to install:
gem install activerecord-mysql2-adapter
But this gem doesn't exist. I'm pretty confused. I've tried many different versions of mysql2 and none seem to work. Any ideas?
Using the following in the gemfile seemed to work:
gem "mysql2", "~> 0.3.11"
It looks like one of your gems requires mysql2 ~> 0.3.10 (meaning >= 0.3.10 && < 0.4), while you are requiring it < 0.3.7. Try removing the constraint on the version and bundle install again ?

I am trying to work on a RoR project, I have created the project called tester to check my db connection, command which I had used is 'rails new tester -d mysql'
my gemfile has mysql2 gem included
I have installed mysql and workbench, and my database.yml looks like this:
default: &default
adapter: mysql2
encoding: utf8
pool: <%=ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
username: root
password: password
host: localhost
socket: MySQL
development: <<: *default
database: tester_development
test: <<:*default
database: tester_test
production: <<: *default
database: tester_production
username: tester
password: <%=ENV['TESTER_DATABASE_PASSWORD'] %>
And my cmd error is following:

Sorry for the long post. I really do not understand what the error is. The error occurs when I try to run rails server.
Help would be appreciated.
It's seems like you are using windows and ruby 2.4
but I think mysql2 library not support ruby 2.4 in windows till now,
So, It would be better to use ruby 2.3 instead of ruby2.4
Hope it will help you.

Someone please help me. Thanks in advance.
install nodejs
sudo apt-get install nodejs
then use
bundle install
This is me trying to use MySql on rails for the first time. This happens with using sqlite3 as well except it points to me do 'gem install activerecord-sqlite3-adapter`,the tells me there is no such gem named it.
I am using the lastest Ruby 2.0.
I am using the lastest Rails 3.2.13
I have the mysql2 (0.3.11) gem
I also have the activerecord-mysql2-adapter (0.0.3)
Yet... it is giving me the following message:
C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/bundler-1.3.5/lib/bundler/rubygems_integration.rb:214:in 'block in replace_gem': Please install the mysql2 adapter: 'gem install activerecord-mysql2-adapter' (mysql2 is not part of the bundle. Add it to Gemfile.) (LoadError)
The bundler ran when I executed rails new [project name]
If it was mysql2 gem's error, this command successfully installs mysql2 on 64 bit Windows systems:gem install mysql2 -v '0.3.11' -- '--with-mysql-lib="C:\MySQL\lib" --with-mysql-include="C:\MySQL\include"'
Gemfile generated is using gem 'mysql2'ok, normal as I have been told.
Database.yml is as follows:
development:
adapter: mysql2
encoding: utf8
reconnect: false
database: shop_development
pool: 5
username: charlie
password: *******
host: localhost
And I have manually created a database called [projectname]_development.

Check for following things
Does your Gemfile have the entry saying gem 'mysql2' ?
What happens when you run $ bundle update command? any errors
Can you try the following command to generate your app,
rails new demo_app -d mysql
What error you get when you try the above app?
Hey everyone! I am having trouble setting up a MySQL database for my rails application. Here are the contents of my database.yml file:
development:
adapter: mysql
encoding: utf8
reconnect: false
database: app_name_dev
pool: 5
username: root
password:
socket: /tmp/mysql.sock
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
adapter: mysql
encoding: utf8
reconnect: false
database: app_name_test
pool: 5
username: root
password:
socket: /tmp/mysql.sock
production:
adapter: mysql
encoding: utf8
reconnect: false
database: app_name_pro
pool: 5
username: root
password:
socket: /tmp/mysql.sock
I also replaced gem sqlite3 with gem mysql in my gemfile and ran bundle install. Now I am trying to create the database for the first time with rake db:create. I am getting the following error:
$ rake db:create --trace

Can someone please explain what I am doing wrong? Thanks!
The MySQL server had not been running on my machine when I tried to run rake db:create. Careless mistake :P
Try using this as your database.yml:
# SQLite version 3.x
# gem install sqlite3-ruby (not necessary on OS X Leopard)
development:
adapter: sqlite3
database: db/development.sqlite3
pool: 5
timeout: 5000
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test: &TEST
adapter: sqlite3
database: db/test.sqlite3
pool: 5
timeout: 5000
production:
adapter: sqlite3
database: db/production.sqlite3
pool: 5
timeout: 5000
cucumber:
<<: *TEST
In my development process i use this config:
development:
adapter: mysql2
database: my_db
encoding: utf8
username: rails
password: rails
host: localhost
