Ruby On Rails的MySQL Gem [英] MySQL Gem for Ruby On Rails

问题描述

我到处搜索，没有一个解决方案可以解决我的问题.我已经使用SQLite而不是MySQL构建了Rails应用程序.对于这个特定的项目，我需要MySQL.当我尝试引导服务器时，出现错误，因此尝试为MySQL安装gems并收到另一个错误.有人有见识吗?谢谢！

I have searched everywhere and no ones solutions solve my problem. I have built rails apps using SQLite but not MySQL. For this particular project, I need MySQL. When I attempt to boot the server I get an error, so I attempt to install the gems for MySQL and get another error. Does anyone have any insight? Thank you!

    rails server
    Could not find gem 'mysql2 (>= 0)' in any of the gem sources listed in your Gemfile.

    sudo gem install mysql2
    Building native extensions.  This could take a while...
    ERROR:  Error installing mysql2:

推荐答案

我遇到了这个问题.您需要安装具有本机扩展的mysql gem.

I had this problem. You need to install the mysql gem with native extensions.

您可能正在寻找的行是这样的:

The line you're probably looking for is this:

$ ARCHFLAGS="-arch x86_64" gem install mysql2 --version '~> 0.2.7' -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
