用于Ruby On Rails的MySQL Gem

我到处搜索,没有解决方案解决我的问题。 我使用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。 当我尝试启动服务器时出现错误,因此我尝试为MySQL安装gems并获得另一个错误。 有没有人有任何见解? 谢谢!

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: ERROR: Failed to build gem native extension. /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/ruby.h Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/mysql2-0.2.7 for inspection. Results logged to /Library/Ruby/Gems/1.8/gems/mysql2-0.2.7/ext/mysql2/gem_make.out 

我有这个问题。 您需要使用本机扩展安装mysql gem。

您可能正在寻找的这条线是这样的:

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