I am having some problems when trying to install gem install mysql2 -v '0.3.17' for Rails. When I try to install it by running gem install mysql2 -v '0.3.17' or gem install mysql2 -v '0.3.17' it gives me the following error:
ERROR: Error installing mysql2:

How can I fix this and successfully install mysql2?
Thanks all .
I am in Ubuntu 15.04 and I got the same error as stated above.
I did :
sudo apt-get install libmysqlclient-dev
After this I did:
gem install mysql2
And now I can successfully do
rails new <app_name> -d mysql
without any errors.
Install libmysqlclient-devel:
CentOS/Fedora:
yum install -y libmysqlclient-devel
Ubuntu:
apt-get install -y libmysqlclient-dev
Mac:
brew install mysql
Hope it helps.
hi this might be happening for two reason.
1) You did not install your mysql server for that try
$ brew install mysql
2) didn't specified mysql_config when you are trying to install mysql2 for this try with
$ gem install mysql2 -- --with-mysql-config=/usr/local/Cellar/mysql/5.6.24/bin/mysql_config
You need to install MySQL server first. You probably don't have it at the moment.

While following a tutorial I got an error while running rails server which said
Could not find gem 'mysql2 (~> 0.5)' in rubygems repository
https://rubygems.org/ or installed locally. The source does not
contain any versions of 'mysql2'
Run bundle install to install missing gems.
later I ran the command suggested and again I got an error

I'd appreciate it if someone could help me out with this one,
Thank you.
Try following command
sudo apt-get install ruby-dev
sudo apt-get install libmysqlclient-dev
sudo gem install mysql2
I have this in the Gemfile:
gem 'mysql2'
But when I run bundle update, I get this error message:
An error occurred while installing mysql2 (0.3.16), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.3.16'` succeeds before bundling.
I've tried to move this into the production section, like this:
group :production do
gem 'mysql2'
end
But after running bundle update, the result is the same. This section is processed only in the production mode, or not?
How to get rid of this error message on localhost?

On Ubuntu, run
sudo apt-get install libmysqlclient-dev
Or, if you use MariaDB, run
sudo apt-get install libmariadbclient-dev
Looks like there is no mysql2 gem installed in your machine.As you are using Mac OSX,you should be installing mysql2 gem like this
gem install mysql2 -- --with-mysql-dir=/usr/local/opt/mysql/
If the above command did't work,try like this
sudo gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
And after try
bundle install
This should fix the error.
Source
Add this in Gemfile:-
gem 'mysql2', '0.3.16'
Then:-
bundle install
After that try:-
bundle update
I just installed mysql via $ brew install mysql and it fixed the problem.
I've ended up with a near-identical error message from attempting to build on a machine without gcc-c++ installed; mkmf is failing to compile a simple c program because the compiler flat out isn't there.
If you're on CentOS, you want sudo yum install gcc-c++. On Ubuntu, it's sudo apt-get install g++. It's a little disappointing that old versions of ruby-devel don't have a dependency on g++.
Is there anyway I could install MySQL gem for rails without Xcode? Many sites have mentioned XCode as optional requirement for installation. But Command line tools is installed.
I have installed rails , ruby, homebrew, MacPorts without XCode.But MySql gem could not be installed
Note: I have installed Command line tools for Xcode. But not full Xcode.
I have followed these references,
http://scotty-t.com/2012/04/02/intstalling-mysql-5-5-on-os-x-mountain-lion/
With setting path in bash_profile
But I keep on getting these errors while trying
sudo gem install mysql

Should I install XCode first? Thanks in advance!
While you exec sudo gem install mysql, you're installing a gem which names mysql, not the database. This gem depende on a file named libmysql, which come with the mysql database.
In other words, you have to install mysql db on your machine first, then install the gem. Otherwise, the gem can't build because it can't find the file it need.
Since you have homebrew, you can install mysql db by exec brew install mysql. After that, sudo gem install mysql could work.
Do you have installed mysql-devel ? If not, try this
$ sudo yum install mysql-devel ;sorry it's for fedora
do it for lion, then
$ gem install mysql
If there still is error, try add a config path when you install the gem.
I got this error:

I have tried:
uninstall mysql2 and install it again
uninstall mysql with apt-get
installd dev-tools from mysql
and almost all the pages on Google
How can I fix this?
You need to install libmysqlclient-dev before installing the mysql2 gem:
sudo apt-get install libmysqlclient-dev
gem install mysql2
This should fix this problem on the latest Ubuntu versions.
Thank Andre Schweighofer, just to it
sudo apt-get install libmysqlclient-dev
gem install mysql2
..
bundle update
bundle install
DONE !!!
It require to install mysql development package
yum install mysql-devel
Its helful to use the search here ;): ruby-mysql
here is another thread ;) with the same problem: ruby-mysql2
and many more when you search for "ruby mysql2" or something like this.
These are multiple causes of this failure :
Bad versions compatibility between ruby and rubygems
Missing libmysqlclient-dev
gem not locating the
Mysql 32bit on a 64 bit system
Solutions
Install rvm with latest stable release, You can switch after via rvm between ruby versions
curl -L https://get.rvm.io | bash -s stable
Install the dependecy
sudo apt-get install libmysqlclient-dev
locate mysql_config on your system (find / -name mysql_config) and run
gem install mysql -- --with-mysql-config=/path/to/mysql_config
Install the 64 bit version of mysql for your system
It could be due to mysql updated binary ( In my case it was using Mariadb-10.0.31) and on installing the missing library( libmysqlclient-dev ), I got the following message that it would be impossible to resolve:
$ sudo apt-get install libmysqlclient-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
libmysqlclient-dev : Depends: libmysqlclient18 (= 5.5.58-0ubuntu0.14.04.1)
But I resolved the above issue by first installing libmariadbclient-dev as:-
$ sudo apt-get install libmariadbclient-dev
It will install libmysqlclient-dev as well but by first resolving mariadb dependency.
On Ubuntu 10.10, I had to install libmysqlclient16-dev.
The way I solved was to inspect the mkmf.log, which in my case was somewhere in
./gems/ruby-2.2.3/extensions/x86_64-linux/2.2.0/mysql2-0.4.2/mkmf.log
In my case, there was an error that it could not find -lgmp, so it was missing the gmp library , so installed via apt-get , in this case libgmp-dev.

I've tried a couple things, specifying where the built-in MySQL is stored sudo gem install mysql2 -- --with-mysql-dir=/var/mysql and also replacing the built-in mysql with the pre-built 64-bit installer from mysql.com
Any ideas?
Figured it out:
sudo env ARCHFLAGS="-arch x86_64" gem install mysql2 -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
I found out you have to have the package mysql-devel installed ... On Centos
do yum -y install mysql-devel and you're good to go.
I have the same problem on OSX 10.5 with RVM with the "system" Ruby interpreter. Using Ruby 1.8.7 through RVM fixed the situation.
