mysql安裝在Ubuntu和耙分貝：創建

，所以我有一個很大的問題，我想用Rails 2.3.11和1.8.7紅寶石冷杉我安裝我的SQLmysql安裝在Ubuntu和耙分貝：創建

gem install mysql

然後我運行啓動一個項目

rake db:create

，但我的一些搜索我發現那位的溶液中，因爲運行這些命令卸載MySQL的一個後得到一個錯誤

Couldn't create database for {"adapter"=>"mysql", "database"=>"test_development", "encoding"=>"utf8", "reconnect"=>false, "username"=>"root", "pool"=>5, "host"=>"localhost", "password"=>nil}, charset: utf8, collation: utf8_unicode_ci (if you set the charset manually, make sure you have a matching collation)

次運行此行

gem install mysql -- --with-mysql-dir=/usr/local \ --with-mysql-config=/usr/local/bin/mysql_config

，但我得到另一個錯誤

ERROR: Error installing mysql: 
ERROR: Failed to build gem native extension. 

    /home/asnad/.rvm/rubies/ruby-1.8.7-p370/bin/ruby extconf.rb --with-mysql-dir=/usr/local --with-mysql-config=/usr/local/bin/mysql_config 
    extconf.rb:5: command not found: /usr/local/bin/mysql_config --cflags 

    *** extconf.rb failed *** 
    Could not create Makefile due to some reason, probably lack of 
    necessary libraries and/or headers. Check the mkmf.log file for more 
    details. You may need configuration options. 

    Provided configuration options:

--without-opt-dir 
--with-opt-include 
--without-opt-include=${opt-dir}/include 
--with-opt-lib

--without-make-prog 
--srcdir=. 
--curdir 
--ruby=/home/asnad/.rvm/rubies/ruby-1.8.7-p370/bin/ruby

嘗試使用mysql2 gem。
如果您打算爲您的應用程序使用mysql2 gem，那麼您需要先安裝libmysqlclient-dev包。欲瞭解更多詳情： http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you/
