問題描述
我已經(jīng)為此苦苦掙扎了一段時(shí)間.
I've been struggling with this for some time.
我已經(jīng)在我的 Snow Leopard 機(jī)器上安裝了 Rails 3、gem、mysql.一切都很順利，直到我創(chuàng)建了我的第一個(gè)項(xiàng)目并嘗試運(yùn)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(yùn)行后我得到:
jontybrook$ rails server

jontybrook$
據(jù)我所知，問題出在 mysql2 gem 上.MySQL 似乎運(yùn)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(cuò)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(dòng)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(jīng)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(gè)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(shí)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(guān)于庫未加載:嘗試使用 mysql2 gem 在 OS X 10.6 上運(yùn)行“rails server"時(shí)出現(xiàn) libmysqlclient.16.dylib 錯(cuò)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(wǎng)！
