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.

Ruby Bundle Symbol not found: _SSLv2_client_method (LoadError)

Closed 8 years ago.
I installed MySQL using Homebrew (brew install mysql), and then ran $ gem install mysql2 . I'm on a Mac running OSX 10.9.4.
I changed directories into the root of my app, and then try to run the rake db:migrate command, and got this error:

Any ideas on how to remedy this? Thanks.
Well, what are you exactly expecting to happen when you run rake db:migrate? Is some next step going to materialize for you? If you are able to answer this question, you will understand why what you're doing doesn't make sense.
I'll elaborate:
rake db:migrate only works in the context of an existing rails application. Running 'gem install mysql2' will get that library for you on your computer (this command is executed by itself, it doesn't actually have anything to do with Rails itself, or need a Rails app for context). So, there's no linear connection between the two.
rails new myapp
add 'gem mysql2' in the Gemfile
bundle
rake db:create
Or, alternatively:
rails new myapp -d mysql
I have a rails application which is running on Rails 3.2.8 and Ruby 1.9.3.I am also using Mysql server as database.
When I run rake db:migrate, I get the following error:
rake aborted!
Incorrect MySQL client library version! This gem was compiled for 6.0.0 but the
client library is 5.5.34.

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
I'm trying to install the mysql gem v. 2.7 on MacOsX Snow Leopard.
I know a lot has been written about this, and I've read most of it.
If I do the following:
sudo env ARCHFLAGS="-arch x86_64" gem install mysql -v '2.7' -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
I get:
ERROR: While executing gem ... (TypeError)

Instead, trying to install v 2.8 works fine:
sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
Successfully installed mysql-2.8.1

Can you help me? Please, I've been breaking my head on this for 2 days :(
MySQL I'm using is the dmg downloaded from mysql.com. I even tried to uninstall it and install mysql from macports but getting lots of errors, so I had to re-install from mysql.com
I just ran into this issue myself. Googling turned up not only this question (which didn't help me - this project isn't ready for Bundler, plus we're using RVM so sudo is out) but also IRC logs from when I asked the same question on the RVM IRC channel a year ago. (Hmm, this sounds familiar.)
If you don't feel like sifting through the IRC log, here's the summary: newer versions of Rubygems (e.g. 1.6.x, which RVM installs by default with ree-1.8.7, which is what we were using) don't play well with the mysql gem. Try this:
ree-1.8.7 $ rvm rubygems 1.5.2
Removing old Rubygems files...
Installing rubygems-1.5.2 for ree-1.8.7-2012.02 ...
Installation of rubygems completed successfully.
ree-1.8.7 $ env ARCHFLAGS="-arch x86_64" gem install mysql -v 2.7 -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
Building native extensions. This could take a while...
Successfully installed mysql-2.7
1 gem installed
Installing ri documentation for mysql-2.7...
Installing RDoc documentation for mysql-2.7...
ree-1.8.7 $
Works a treat.
Found the way to install mysql gem and make it work:
I installed rvm, istalled ruby 1.8.7 and made it the defualt ruby (instead of the system one), then I compiled and reinstalled all the gems using
sudo env ARCHFLAGS="-arch x86_64" bundle install
Now it works!
I just ran in to this problem myself; we have an app that's running on an older version of ruby and rails.
I am using:
rbenv
Mac OS - Mavericks
bundler
ruby ree-1.8.7-2010.02
I had to downgrade rubygems:
gem update --system 1.5.2
Then I could install mysql 2.7 (and everything else) with:
sudo env ARCHFLAGS="-arch x86_64" bundle install
I've installed rails, the mysql2 gem, and mysql and have created a project called simple_cms using rails new simple_cms -d mysql. Now when I execute rails server to start WEBricks, I get this bucket of joy:

See:
Unable to start rails server but my mysql version is different and that doesn't solve it even with changing 0.2.6 to 0.3.11
The issue is that Ruby can't find the libraries necessary to build the MySQL gem, there are many ways to fix this but since it looks like you're just starting up on Ruby, I think it's worth to prepare your environment so you don't see this kind of stuff again, here are the steps:
First I would recommend you to install Homebrew, with Homebrew installed, install MySQL:
brew install mysql
This will install MySQL in your machine including the necessary libraries to build the MySQL gem when you need it.
Then you should to install RVM to install your rubies (before installing RVM you need to run brew install git). Once you install RVM, you can start installing any rubies you would like to.
And then you ask, why can't you use the built in Ruby? Rails will drop support for the Ruby 1.8.* branch on 4.0 and the community in general uses RVM (or rbenv) to install and manage rubies installed to your machine.

when i try to install activerecord-mysql2-adapter by :gem install activerecord-mysql2-adapter
ERROR: Could not find a valid gem 'activerecord-mysql2-adapter' (>= 0) in any repository
please help me
thanks
The problem is because you are trying to install the latest version of mysql2 which is incompatible with rails 3.0.x version
SO, in your Gemfile change the line for mysql2 gem for this:
gem 'mysql2', '< 0.3'
then bundle command
and then when the new mysql2 gem file ( i think is 0.2.7 ) you will solve the problem.
if still not working try this too:
sudo install_name_tool -change libmysqlclient.18.dylib /usr/local/mysql/lib/libmysqlclient.18.dylib /Users/YOUR_USER_NAME/.rvm/gems/1.8/gems/mysql2-0.2.7/lib/mysql2/mysql2.bundle
gem 'mysql2', '< 0.3' is the only way on Rails 3.0.7 (before 3.1)
UPDATE: sorry, that was not the case also, did't work either, there is a better way:
vendor/bundle/ruby/1.9.1/gems/mysql2-0.3.2/lib/active_record/connection_adapters$[rails307]$ ls
em_mysql2_adapter.rb mysql2_adapter.rb
take mysql2_adapter.rb file from mysql2 gem version 0.2.x and copy it to the above location
now it works for me with just gem 'mysql2' in Gemfile
After trying the solution offered by #eveevans I was still having version issues. Then reading the suggestion by #rubyconvict, I thought instead about using the -v option for gem rather than pushing files about.
Here's what I found eventually resolved my struggle with the dreaded "version of mysql2 (0.3.2)" message on DreamHost:
# in mysql, create example_app & example_app_test ...
# ... for the purposes of this example only, production == development db
rails new example_app --database=mysql --freeze
cd example_app
vim config/database.yml
# change settings for host, user, password ...
# ... database for test (example_app_test) ...
# ... & database for production & development (example_app)
vim Gemfile
# gem 'mysql2', '< 0.3'
gem uninstall mysql2 # if installed: gem list -d mysql2
gem install mysql2 -v 0.2.7
rake db:migrate
From there, I can move onto other RoR fun, like perhaps modifying routes (vim config/routes.rb ... however your mileage may vary).
WARNING: Please use the 0.2.x
releases if you plan on using it in
Rails <= 3.0.x
so in short just use the latest in the 0.2.x branch for the mysql2 gem.
