I don't know how to install mysql2.
I'm using:
Ruby On Rails 3.2.14
Ruby 2.0.0
Mac OS X 10.9 ("Mavericks")
Installing mysql2 (0.3.13)
An error occurred while installing mysql2 (0.3.13), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.3.13'` succeeds before bundling.

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.

You need to install mysql locally. Since you're on OS X you can use Homebrew.
# to Install homebrew
ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"
# to install mysql through homebrew
brew install mysql
I ran to the same problem. To fix this problem, open a command prompt. go to your application folder. And type: gem install mysql2 -v 0.3.11 this version is working great.

I am going to install some gems in my rails application using bundle install on Debian testing(stretch). I get this error:

For gems with C extensions to compile, you'll need to install the ruby-dev package:
$ sudo apt-get install ruby-dev
When I run a bundle on a rails project I seem to be getting the following:
Installing pg 0.17.1 with native extensions

I have visited the following SO questions:
An error occurred while installing pg (0.17.1), and Bundler cannot continue
Installing pg -v 0.17.1
Installing PG gem on OS X - failure to build native extension.
Additionally to this I've tried executing the following:
gem install pg
env ARCHFLAGS="-arch x86_64" gem install pg
gem install pg -- --with-pg-config=/usr/local/Cellar/postgresql/9.4.5/bin/pg_config
And I keep getting:
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.
FYI I have rbenv installed too. Also tried a rbenv rehash also and executed the above commands and have had no luck. I've also tried uninstalling and reinstalling Postgres and get the same. To also be on the safe side i've also ran:
brew update
brew uinstall posgresql > brew install postgresql
updated Xcode
Info:
Mac OSx Yosemite 10.10.5
Postgres v9.4.5
rbenv v0.4.0
rbenv global => 2.0.0-p247
I don't know Mac, but I've had this problem on Windows.

The issue is here:
Failed to build gem native extension
When you install a gem, many of the advanced ones actually compile / "build" through the extconf.rb file. I've forgotten the significance of this, but it basically allows the gem to run natively on the OS environment you're using.
In short, the error occurs because your OS does not have access to the "developer headers" the gem requires to compile.
The most common instance of this problem is with the mysql2 gem on Windows, but happens for others too.

What you need is to download PGSQL on your system before attempting to install the gem.
After installing PGSQL, you may need to reference the developer headers with some "switches", but it does not appear to be the case in this instance:
Installing PG gem on OS X - failure to build native extension
Install Xcode command line tools (Apple Developer site)
brew uninstall postgresql
brew install postgresql
ARCHFLAGS="-arch x86_64" gem install pg
Maybe this won't work? I don't know... I know that in Windows, you have to install the binaries before expecting the gem to work.
Greetings I hope I can help. May I ask how you created your rails project? Did you simply use:
rails new *appname*
If so maybe try creating a new rails app like so:
rails new *appname* -d postgresql
And before you create your database and run migrations/seed, you should go into "config/database.yml" and change the username and password to the postgreSQL user that you've hopefully setup after installing postgreSQL on your machine.
Good Luck!
I'm trying to learn Ruby on Rails with a online tutorial.
[rails version]: Rails 3.2.13
[ruby version] : ruby 1.9.3p392 (2013-02-22 revision 39386) [x86_64-linux]
When I execute the command:
rails new first_app
I get:

Sure enough, I ran gem install json -v '1.7.7 as listed, however the results are:

Has anyone seen that?
If you are in a "rpm" system (Fedora or Red Hat) use:
sudo yum install -y gcc ruby-devel libxml2 libxml2-devel libxslt libxslt-devel
It solved the problem for me.

If you have ports installed try:
port install sqlite
Or if you are using brew:
brew install sqlite
Does that fix it?
