Ruby on Rails mysql2 gem故障排除

Question

I have created new ruby on rails project with mysql database. I have run mysql server by running mysql.server start When I try to run rake db:create, I got following error:

dyld: lazy symbol binding failed: Symbol not found: _mysql_init
Referenced from: /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle
Expected in: flat namespace

dyld: Symbol not found: _mysql_init
Referenced from: /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle
Expected in: flat namespace

Anybody can solve this issue? Please reachout me. Regards.

Answer 1

The salient details are that you need to update the DYLD_LIBRARY_PATH to include /usr/local/mysql/lib . The easiest way of doing that is to add the following to your ~/.bashrc file:

export DYLD_LIBRARY_PATH="/usr/local/mysql/lib:$DYLD_LIBRARY_PATH"

I went into a little more detail in a blog post here: http://www.bartbusschots.ie/blog/?p=2186
