問題描述
我已經為此苦苦掙扎了一段時間.
I've been struggling with this for some time.
我已經在我的 Snow Leopard 機器上安裝了 Rails 3、gem、mysql.一切都很順利，直到我創建了我的第一個項目并嘗試運行
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
運行后我得到:
jontybrook$ rails server

據我所知，問題出在 mysql2 gem 上.MySQL 似乎運行良好，我的 Gemfile 引用了 mysql2，我的 database.yml 文件似乎也正常.
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.
錯誤提到
Reason: image not found - /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle
還有
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 有沒有！?
MySQL2.bundle is there!?
如果我使用舊的 mysql gem，WEBrick 啟動正常.但這并不理想，不是嗎?
If I use the old mysql gem, WEBrick boots fine. But that's not ideal, is it?
我已經嘗試了谷歌能給我的一切！非常感謝任何幫助.
I've tried everything google can give me! Any help much appreciated.
推薦答案
我從來沒能得到這些答案中的任何一個對我有用，但這是我用來讓它對我有用的命令.這樣你就不需要每次更新你的mysql時都使用 install_name_tool
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
這篇關于庫未加載:嘗試使用 mysql2 gem 在 OS X 10.6 上運行“rails server"時出現 libmysqlclient.16.dylib 錯誤的文章就介紹到這了，希望我們推薦的答案對大家有所幫助，也希望大家多多支持html5模板網！
