I am getting some errors whilst connecting to MySQL and the fixing of it led me to upgrade the mysql2 gem.
I ran this command to install mysql2:
ruby install mysql2
and now "gem list" shows this gem: mysql2 (0.3.2)
But I think it isn't part of my application environment still since the server gives this error:
Please install the mysql2 adapter: `gem install activerecord-mysql2-adapter` (no such file to load -- active_record/connection_adapters/mysql2_adapter)
I have RVM and I've used bundler to make a gemset for this application. How can I add mysql2 to this application's gemset?
This is my gemfile:
source 'http://rubygems.org'
gem 'rails', '3.0.7'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'sqlite3'
gem 'mysql2' , '0.3.2'
And this is my MySQL adapter version:
$bundle show mysql2
/home/agenadinik/workspace/udfr/mysql2/ruby/1.9.1/gems/mysql2-0.3.2
Also
$ rvm gemdir /home/agenadinik/.rvm/rubies/ruby-1.9.2-p180/bin/gem:4: warning: Insecure world writable dir /home/agenadinik in PATH, mode 040777 /home/agenadinik/.rvm/gems/ruby-1.9.2-p180
Note that you cannot use mysql2 version 0.3.x with Rails version less than 3.1.x. I assume you are using Rails 3.0.x or below (and thus you need to use mysql2 version 0.2.x):
Here is an example of how to set up a gemset and the Gemfile to use mysql2:
~/code/myapp $ rvm gemset create myapp
~/code/myapp $ rvm use @myapp
<<<<<Edit the Gemfile and add the line gem "mysql2","0.2.7" then save and exit editor.>>>>>
~/code/myapp $ bundle install
~/code/myapp $ bundle show mysql2
<<<<<Output should be similar to: /home/<your-name>/.rvm/gems/ruby-<some-version>@myapp/gems/mysql2-0.2.7>>>>>
If you're using Bundler, you should add
gem "mysql2"
to your Gemfile
, then run bundle install
On Rails >= 3.2.0 you will see this if you are using an older version of bundler. Update bundler to >= 1.1.1:
gem update bundler
Once you have done this, update your gems:
bundle install
