ERROR: Error installing mysql2: ERROR: Failed to build gem native extension
Solution 1
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.
Solution 2
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
Solution 4
You need to install MySQL server first. You probably don't have it at the moment.

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.

How can I fix this and successfully install mysql2?
Thanks all .

Lukasz Muzyka over 9 yearsThere you go, head over to the oracle website and install it on your machine. When you're done, gem will install

bestmike007 over 9 yearsIt's required for mysql2 gem. Just install it before ``` gem install mysql2 ``` or ``` rails new app_name -d mysql ```.

0112 about 8 yearsOn Fedora this worked for me:
yum install mysql-devel
. (Or rather:dnf install mysql-devel
)
