I'm having the exact issue as described in this question: MYSQL Installation Troubles. Unfortunately none of the answers helped me (and it's closed).

I try to learn Ruby on Rails and don't get MySQL working (so it is programming related).

I typed: rake db:create and got:

!!!The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql. rake aborted! no such file to load -- mysql (See full trace by running task with --trace) HD-Auckland:shoutbox max$ gem install mysql WARNING: Installing to ~/.gem since /Library/Ruby/Gems/1.8 and /usr/bin aren't both writable.

So as it told me I tried sudo gem install mysql and got:

I also tried this command sudo gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config and got the same error!

What can I do? I only want to migrate my db to the MySQL server!

Thanks for help, Mexx

Update:

Thanks for all the great response! Yes, I am on Snow Leopard. I downloaded mysql from here http://dev.mysql.com/downloads/mysql/5.1.html#macosx-dmg and installed it. I then followed Hivelogic's guide for the mysql installation.

when I now type: sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_configor sudo gem istall mysql or sudo gem install mysql -- --with-mysql-dir=/usr/local/mysql

I will get:

Building native extensions. This could take a while... fotoSuccessfully installed mysql-2.8.1 1 gem installed Installing ri documentation for mysql-2.8.1... No definition for next_result No definition for field_name No definition for field_table No definition for field_def No definition for field_type No definition for field_length No definition for field_max_length No definition for field_flags No definition for field_decimals No definition for time_inspect No definition for time_to_s No definition for time_get_year No definition for time_get_month No definition for time_get_day No definition for time_get_hour No definition for time_get_minute No definition for time_get_second No definition for time_get_neg No definition for time_get_second_part No definition for time_set_year No definition for time_set_month No definition for time_set_day No definition for time_set_hour No definition for time_set_minute No definition for time_set_second No definition for time_set_neg No definition for time_set_second_part No definition for time_equal No definition for error_errno No definition for error_sqlstate Installing RDoc documentation for mysql-2.8.1...

And doing rake db:create will end up with:

for some reason (maybe because i'm using rubygems 1.3.7 or installing mysql-2.8.1) 

sudo gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

did not work for me so after taking a look at gems/mysql-2.8.1/ext/mysql_api/extconf.rb i found out that the extconf.rb looks in the PATH for mysql_config so i tried

export PATH=$PATH:/usr/local/mysql/bin sudo gem install mysql

and did the job

Are you on snow leopard? You have to execute the C dependencies compiles with x64 headers, try:

sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

You don't have to do that. I installed 64-bit MySQL on Snow Leopard from source using these instructions and it works fine: hivelogic.com/articles/compiling-mysql-on-snow-leopard

I have run into issues with the MySQL gem myself and these are the only 2 links I actually bookmarked, so one of should have actually worked for me. Thought I'd share.

  1. http://wonko.com/post/how-to-install-the-mysqlruby-gem-on-mac-os-x-leopard
  2. http://rapd.wordpress.com/2007/05/17/battle-against-ror-gem-install-mysql/

The second one is kind of old, so not sure if it still applies.

In order to install the MySQL gem on OS X, you need to install the XCode developer tools that come on your installation disk. You can also download them from http://developer.apple.com.

I just end up with that problem using this command: 

 sudo env ARCHFLAGS="-arch i386" gem install --no-rdoc --no-ri mysql -v 2.8.1 -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

Indeed I needed to install mysql gem version 2.8.1 on my mac OS X Leopard 10.5.8 running the mysql-5.6.2-m5-osx10.5-x86 from dmg file. I had the issue that it couldn't find libraries and I made some manipulations, then it couldn't install because of permissions. I found out that command, added the version I needed and changed architecture to the one corresponding to my mysql installation.

So if somenone still wants to install that version :) let's try ! But we are not a lot installing this probably, and less on Leopard!

The correct gem to use is mysql2.

I had the same problem. I solved installing first the adapter:

gem install activerecord-mysql2-adapter

Then, install mysql2 gem using

sudo gem install mysql2 -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
