I have recently installed rvm to use rails5 along with rails3.x version in my current system. When i tried to create new rails5 application, i have got the below error
Could not find proper version of railties (3.2.13) in any of the sources
Run `bundle install` to install missing gems.
And when i try to do bundle install, i got stuck with this
gem install mysql2 -v '0.3.11'

Got stuck with this for quite some time, any help would be much appreciated.
From Terminal try following:
For Ubuntu:
sudo apt-get install mysql-client libmysqlclient-dev
sudo gem install mysql2
For Mac:
brew install mysql
sudo gem install mysql2
try the below:
gem install rails
After that install mysql server
sudo apt-get install mysql-client libmysqlclient-dev
then bundle install

For reference I ran brew install mysql beforehand and it ran successfully. Also I tried uninstalling all versions of brew's mysql references just in case.
Is there something im missing? I've looked around and most pages point back to making sure you run brew install mysql which I have.
In case I wasn't more clear with my above explanation, the failure I am getting is after successfully running brew install mysql the error is from trying to install the gem afterwards via gem install mysql2 -v '0.3.20'
Any idea?
Thanks
How to make it work on MacOS Mojave.
Make sure openssl is installed on Mac via Homebrew:
brew install openssl
Then install mysql2 gem following this special way:
gem install mysql2 -v 'x.x.x' -- --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include
where x.x.x - specified version of the mysql2 gem.
Just for reference what ended up working was xcode-select --install which seemed to install the OpenSSL libraries which took care of the ld: library not found for -lssl issue.
I'm running Ubuntu 14 and when I try to run rails server but I get this error:
Could not find gem 'mysql2 (>= 0) ruby' in the gems available on this machine.
Run bundle install to install missing gems.
So I run the bundle install and then I get the following error.

Start again from scratch and this time you should install RVM as it is really good at handling all this stuff for you.
http://rvm.io/rvm/install
Make sure you get all the dependencies first, this code will check to see what you have and don't have:
for name in {bash,awk,sed,grep,ls,cp,tar,curl,gunzip,bunzip2,git,svn} ; do which $name ; done
Its also worth looking at the prerequisites page: http://rvm.io/rvm/prerequisites
You can run the below code to install rvm with Ruby 2.1.1 and Rails:
\curl -sSL https://get.rvm.io | bash -s stable --rails
Then To start using RVM:
/bin/bash --login
Its definitely worth using RVM it will make your life much easier when managing your ruby versions, gems etc, just make sure you read through the webpage so that you know how to use it.

I am unable to run Ruby on Rails bundle install with Ruby 1.9.3 and Mountain Lion. It will not install the MySql2 gem. I have installed Ruby on Rails about 10 times on a mac OS X Lion, so I am very familiar with the steps, but am unable to get the MySQL gem into install. This is the error I get. Thanks in advance.

This guy had the same problem : Unable to install mysql2 gem OS X Mountain Lion
Are you using the brew version of mysql?
If you're using rvm, and possibly added mysql2 outside of rvm, try these steps: Confirm that your Gemfile says:
gem 'mysql2'
or for Rails2.x:
gem 'mysql2', '~> 0.2.11'
then:
$ cd RAILS_ROOT $ gem uninstall mysql2
Select gem to uninstall:
1. mysql2-0.2.11
2. mysql2-0.3.6
3. All versions
> 3 # select "All versions"
$ rvm gemset install mysql2
$ bundle install
Now rails should start properly.
1) first install homebrew from terminal :
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
2) Install mysql : "brew install mysql"
3) Install mtsql2 : "gem install mysql2"
It should work.

First question: Has anyone got Rails mysql2 running with MySql 5.5.1 on Ubuntu? I have it running on another system with 5.1. The gem description is vague on supported MySql versions.
Second question: Has anyone encountered this problem? I± have battled various library issues with the mysql2 gem over the passed year or so but this seems to be different.
Any assistance is gratefully recieved.
BTW: Reverting back to MySql 5.1 is a valid solution!
Regards
Peter
Or just apt-get install libmysqlclient-dev and then gem install mysql2
So the problem appears to have been a missing library and some links. Doing the following solved the issue.
Get the new and install the libmysqlclient-dev deb package kindly provided by Nathan Rennie Waldock
wget http://ppa.launchpad.net/nathan-renniewaldock/ppa/ubuntu/pool/main/m/mysql-5.5/libmysqlclient-dev_5.5.24-1~ppa1~natty_amd64.deb./;l
dpkg -i libmysqlclient-dev_5.5.24-1~ppa1~natty_amd64.deb
Then create some links that mysql2 needs as it can't seem to follow the mysql path
cd /usr/lib/
ln -s /usr/local/mysql-5.5.24-linux2.6-x86_64/lib/libmysqlclient_r.a .
ln -s /usr/local/mysql-5.5.24-linux2.6-x86_64/lib/libmysqlclient_r.so .
ln -s /usr/local/mysql-5.5.24-linux2.6-x86_64/lib/libmysqlclient_r.so.18 .
ln -s /usr/local/mysql-5.5.24-linux2.6-x86_64/lib/libmysqlclient_r.so.18.0.0 .
Now happily install the mysql2 gem
sudo gem install mysql2

Had the same issue in Ubuntu 12.04 also using the ppa mentioned in the accepted answer.
But also there was no libmysqlclient file on my system with _r in the name.
Googling around I found out that package builders have started to drop the _r suffix from the files, so that might have happened between 11.10 and 12.04.
Also the paths were a bit different to the once mentioned so these are the symlinks that I had to create:
ln -s /usr/lib/x86_64-linux-gnu/libmysqlclient.a ./libmysqlclient_r.a
ln -s /usr/lib/x86_64-linux-gnu/libmysqlclient.so ./libmysqlclient_r.so
ln -s /usr/lib/x86_64-linux-gnu/libmysqlclient.so.18 ./libmysqlclient_r.so.18
ln -s /usr/lib/x86_64-linux-gnu/libmysqlclient.so.18.0.0 ./libmysqlclient_r.so.18.0.0
I had this problem as well...
I did dpkg -r mysql-devel as when I was trying to do apt-get install libmysqlclient-dev I got an error saying:

After doing this, gem install mysql2 worked! yay :)
