El Capitan upgrade: Library not loaded: /usr/local/lib/libmysqlclient.18.dylib
Solution 1
I was getting the same issue earlier on, I fixed it by reinstalling the gem mysql2
.
Solution 2
this will solve your problem:
gem pristine mysql2
solution by Cesar Sulbarán
Solution 3
For those on OS X El Capitain or more, this fix my problem:
sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/local/lib/libmysqlclient.18.dylib

Solution 4
I had an analogous problem in python: libmysqlclient.20.dylib
instead of 18
on El Capitan. pip install --upgrade mysql
fixed it, but only works in python2.
Solution 5
I'm using Homebrew so I've fixed this problem by clearing up everything step by step:
Comment out the mysql2 gem in in the Rails app Gemfile
"# gem 'mysql2'"
Remove mysql2 gem from bundle
bundle install
Uninstall the mysql2 gem (all versions)
gem uninstall mysql2
Update Homebrew
brew update
Uninstall all versions of mysql
brew uninstall --force mysql
Reinstall mysql
brew install mysql
Uncomment mysql2 gem in Gemfile
gem mysql2
Add mysql2 to bundle
bundle install
This approach might be a bit overkill but feels clean to me.

As you see I'm having
libmysqlclient.20.dylib
, it's20
not18
, otherwise I'd follow the solution here.I've recently upgraded to El Capitan but not sure it that's the cause.
UPDATE:
Thanks to @Rashmirathi for the hint to re-install the gem.
Just wanted to note, I needed also to specify in Gemfile as:
gem 'mysql2', '~> 0.3.18'
Otherwise I had error:
Specified 'mysql2' for database adapter, but the gem is not loaded. Add
gem 'mysql2'
to your Gemfile (and ensure its version is at the minimum required by ActiveRecord).But finally I got error:
Mysql2::Error
