Library not loaded：libmysqlclient.16.dylib错误，当试图在OS X 10.6上使用mysql2 gem运行'rails server'时 [英] Library not loaded: libmysqlclient.16.dylib error when trying to run 'rails server' on OS X 10.6 with mysql2 gem

问题描述

我一直在为此付出一些努力。

我在Snow Leopard机器上安装了Rails 3，gem，mysql。直到我创建了第一个项目并试图运行

  rails server 
  
  
 
 $ b 
 
 $ b $ p $  jontybrook $ rails server

据我可以告诉问题是与MySQL2宝石。 MySQL似乎运行良好，我的Gemfile引用了mysql2，我的database.yml文件似乎也没问题。

错误提及

 原因：image not found  -  /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle 
  

但是

  jontybrook $ cd /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2 
 jontybrook $ ls 
 client.rb em.rb error.rb mysql2.bundle result.rb 
  

MySQL2.bundle is there！？

如果我使用旧的MySQL的宝石，WEBrick靴子罚款。但这并不理想，是吗？

我已经试过谷歌可以给我的所有东西！任何帮助我们都非常感谢。

解决方案

我从来没有能够得到任何这些答案为我工作，但这是命令我曾经让它为我工作。这样，每次更新mysql时就不需要使用install_name_tool。

  sudo ln -s / usr / local / mysql /lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib 
  

I've been struggling with this for some time.

I've installed Rails 3, gem, mysql on my Snow Leopard machine. All was going well until I created my first project and tried to run

rails server

Upon running this I get:

jontybrook$ rails server

As far as I can tell the problem is with the mysql2 gem. MySQL seems to be running fine and my Gemfile references mysql2, my database.yml file seems ok also.

The error mentions

Reason: image not found - /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle

And yet

jontybrook$ cd /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2
jontybrook$ ls
client.rb   em.rb       error.rb      mysql2.bundle result.rb

MySQL2.bundle is there!?

If I use the old mysql gem, WEBrick boots fine. But that's not ideal, is it?

I've tried everything google can give me! Any help much appreciated.

解决方案

I was never able to get any of these answers to work for me, but this is the command that I used to make it work for me. This way you don't need to use install_name_tool every time you update your mysql

sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib
