我无法使用 Ruby 1.9.3 和 Mountain Lion 运行 Ruby on Rails 捆绑安装。它不会安装 MySql2 gem。我在 Mac OS X Lion 上安装了 Ruby on Rails 大约 10 次,所以我非常熟悉这些步骤,但无法安装 MySQL gem。这是我得到的错误。提前致谢。

    An error occurred while installing mysql2 (0.3.11), and Bundler cannot continue.
    Make sure that `gem install mysql2 -v '0.3.11'` succeeds before bundling.

我试过 bundle install --path mysql 和 bundle install --system 都没有成功

这家伙有同样的问题:无法安装mysql2 gem OS X Mountain Lion

你用的是 brew 版本的 mysql 吗?

如果您使用的是 rvm,并且可能在 rvm 之外添加了 mysql2,请尝试以下步骤: 确认您的 Gemfile 显示:

宝石'mysql2'

或 Rails2.x:

宝石'mysql2','〜> 0.2.11'

然后:

    $ cd RAILS_ROOT $ gem uninstall mysql2

    Select gem to uninstall:
     1. mysql2-0.2.11
     2. mysql2-0.3.6
     3. All versions
    > 3 # select "All versions" 
$ rvm gemset install mysql2
 $ bundle install

现在rails应该可以正常启动了。

1)首先从终端安装自制软件: ruby​​ -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install )"

2)安装mysql:“brew install mysql” 3)安装mtsql2:“gem install mysql2”

它应该工作。
