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...

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
