How can I proceed?
I have the sam problem. What I did is doing;
gem install --version '0.2.7' mysql2
Then on your Rails's GemFile. Should look like this.
gem 'mysql2', '0.2.7'
Then try again. Hope it help.
Your stacktrace after Step 2 told you what to do:
Please install the mysql2 adapter: gem install activerecord-mysql2-adapter
Update
Also, upgrade your Rails to 3.0.7 - there are a number of security holes (and bugs) in 3.0.3.
Update
Looks like that error message from Rails is wrong, it should have read:
Please use the 0.2.x releases if you plan on using it in Rails <= 3.1
Ie. for anything less than 3.1 you need to pin mysql2 to the 0.2 release, and not allow it to use 0.3. To do this, change your mysql2 line in your Gemfile to this:
gem "mysql2", "~> 0.2"
Then re-run bundle install
rails sWARNING: This version of mysql2 (0.3.2) doesn't ship with the ActiveRecord adapter bundled anymore as it's now part of Rails 3.1
WARNING: Please use the 0.2.x releases if you plan on using it in Rails <= 3.0.x
MySql version '0.2.7' solved my issue.
gem 'mysql2', '0.2.7'
Try this (but I cannot guarantee anything)
Check this post about how to
remove MySQL 5.5.
install MySQL 5.1 (I think I downloaded the 32bit DMG version)
Follow this post to create the GEM.
Hopefully it will work after this. I'll cross my fingers for you.
The above problem occurs presently on EngineYard App Cloud with Ruby 1.9.2 and Rails 3.0.3. Using mysql 2.8.1 barfs b/c EY sets mysql2 adapter. Using mysql2 0.3.2 barfs. So I was seriously stumped. Props to Richard Soutar's answer. It worked.

I am trying to install RoR in Ubuntu 15(64 bit). I have done most of the installation process like installing rvm, ruby, mysql server, creating gemset.
rails new first_app
rvm gemset list
rvm gemset use rails3.2.13
rails new first_app
cd first_app/
bundle install

mysql2 gem compiled for wrong mysql client library

Closed 6 years ago.
I upgraded my Ubuntu from 2014.04 to 2015.04 and now bundle exec rake db:migrate returns an error:

Incorrect MySQL client library version! This gem was compiled for 5.5.37 but the client library is 5.6.25.

How to solve this problem?
I would rather avoid changing server-side versions.
The answers at I can't run "bundle update" because of "mysql2" gem do not solve the problem.
Local versions:
gem 2.4.8
Rails 3.0.19
mysql Ver 14.14 Distrib 5.6.25
Running these commands solved the problem:
gem uninstall mysql2
bundle install
I ran into the same problem and the accepted answer didn't work for me, most likely because I used capistrano, which installs all gems into a per-app shared directory.
bundle show mysql2
(run in your app's folder) will show you where mysql is installed. Then delete that as well as the the specification.
rm -rf /path/to/application/shared/bundle/ruby/<version>/gems/mysql2-<version>
rm /path/to/application/shared/bundle/ruby/<version>/specifications/mysql2-<version>.gemspec
should do the trick. Alternatively just delete the complete bundle/* and reinstall everything.
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?
Im trying to setup my rails server on OSX 10.8 but I can't get my rails server to run.
- Currently Im using a Zend Server with mysql 5.1.
- I also have istalled brew and brew mysql.
- And I used: gem install mysql2 -- --srcdir=/usr/local/mysql/include --with-opt-include=/usr/local/mysql/include
the server worked already but now, I always get this loadError below.

rake db:migrate giving error for mysql2
after that I changed my database.yml as follows:
development:
adapter: mysql2
socket: /usr/local/zend/mysql/tmp/mysql.sock
#host: 127.0.0.1
so that I used my local zend MySQL socket.
In my case the ""Can't connect to MySQL server on '127.0.0.1' (61) (Mysql2::Error)" was gone.
Thx #dinnouti for the usefull links above.
Final edit: I played with a few different files got some more errors and then reinstalled rvm and everything else from the start, found a few fixes and edited them and finally everything works. thank you everyone for your help
Edit: I have noticed that it says Library not loaded: /usr/local/mysql-5.5.10-osx10.6-x86_64/lib/libmysqlclient.18.dylib (LoadError)
But I have mysql 5.5.11, how do I fix that?
I literally have searched for the past 3 hours, but found nothing that worked
Same error occurs when I either try to launch the server or generate a model
I have bundler and mysql2 gems.
builder (2.1.2)
bundler (1.0.12)
erubis (2.6.6)
i18n (0.5.0)
mail (2.2.17)
mime-types (1.16)
mysql2 (0.2.7)
I get the following output:

Whenever you get load errors you should make sure you have all of the dependencies installed and in place.
Make sure you have gem mysql2 in your Gemfile.
Install bundler if you don't already have it with gem install bundler.
Run bundle (same as bundle install).
Then try running the server again.
mysql2 with rails 3.0.3 is give some error so try to update rails version with 3.0.6
it working fine so try
