Did you install the MySQL db server? If so, does this file actually exist?:

<pre><code>/usr/local/mysql/bin/mysql_config
</code></pre>

If mysql isn't installed, install that first. Then make sure that the mysql_config script you point to is actually there.

What worked for me is adding this to ~/.bash_profile:

<pre><code>export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/
</code></pre>

After installing the MySQL gem like this (64 bit version on an Intel osx 10.6):

<pre><code>export ARCHFLAGS="-arch x86_64" ; sudo gem install --no-rdoc --no-ri mysql -v 2.7 -- --with-mysql-dir=/usr/local --with-mysql-config=/usr/local/mysql/bin/mysql_config

<blockquote>
 The bundled mysql.rb driver has been
 removed from Rails 2.2. Please install
 the mysql gem and try again: gem
 install mysql.
</blockquote>

And when i try to do gem install mysql it still doesnt work and im getting this error.

<blockquote>
 WARNING: Installing to ~/.gem since
 /Library/Ruby/Gems/1.8 and /usr/bin
 aren't both writable. WARNING: You
 don't have

 not run.
</blockquote>

</blockquote>

我收到一个rails应用程序的错误。捆绑的mysql.rb驱动程序已经从Rails 2.2中删除。请安装mysql，然后再试一次: gem安装mysql。而且，当我尝试做创业板安装mysql，它仍然不工作，我得到这个错误。警告:从/Library/Ruby/Gems/1.8和/usr/bin安装到~/..gem并不都是可写的。警告:您的路径中没有/Users/bartligthart/. gem
