Question

Ruby已安装在Mac上。所以我刚刚安装了rails。

ruby 1.8.7 (2009-06-12 patchlevel 174) [universal-darwin10.0]

rails 2.3.11

gem 1.3.5

当我尝试：gem install mysql我收到此错误：

89-235-235-64:~ vitali$ gem install mysql
WARNING:  Installing to ~/.gem since /Library/Ruby/Gems/1.8 and
      /usr/bin aren't both writable.

不明白该怎么做。 gem安装mysql安装没有MySQl本身或者我应该下载并安装MySQL作为prorgamm？如果是，从什么资源，什么版本，如何安装？请帮助我，我的新手在mac上。非常感谢！

你几乎肯定需要安装MySQL以安装MySQL gem（更好的是mysql2 gem，Rails也可以使用 - 只需在你的database.yml文件中使用mysql2而不是mysql）。 / p>

我发现在Mac上格式化MySQL的最佳方法（无可否认，很少）是使用Homebrew。所以，如果你没有安装Homebrew，我会从那开始......一旦完成，它应该是运行sudo brew install mysql，并在安装完成后运行它提供的指令。
