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:
ERROR: Failed to build gem native extension.
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the file for more
details. You may need configuration options.
Provided configuration options:

Gem files will remain installed in `..../gems/ruby-1.9.3-p392/gems/mysql2-0.3.17 for inspection`.
Results logged to `.../gems/ruby-1.9.3-p392/extensions/x86_64-darwin-14/1.9.1/mysql2-0.3.17/gem_make.out`
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.
