Bundle安裝不會安裝與Ruby 1.9.3，Rails3和Mac Mountain Lion的mysql2 gem

Question

我無法運行Ruby on Rails與Ruby 1.9.3和Mountain Lion捆綁安裝。它不會安裝MySql2 gem。我在Mac OS X Lion上安裝了Ruby on Rails大約10次，所以我對這些步驟非常熟悉，但無法將MySQL gem安裝到其中。這是我得到的錯誤。提前致謝。

    Make sure that `gem install mysql2 -v '0.3.11'` succeeds before bundling. 

我試圖捆綁安裝--path mysql和捆綁安裝--system既不如果你使用RVM，並可能增加mysql2 RVM之外，請嘗試以下步驟工作

Answer 1

這傢伙有同樣的問題：Unable to install mysql2 gem OS X Mountain Lion

你用mysql的BREW版本？

Answer 2

：確認您的Gemfile說：

寶石 'mysql2'

或Rails2.x：

寶石 'mysql2'， '〜> 0.2.11'

則：

$ 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 

現在應該軌道正常啓動。

Answer 3

1）首先從終端安裝自制： 紅寶石-e 「$（捲曲-fsSL https://raw.github.com/Homebrew/homebrew/go/install）」

2）安裝MySQL： 「釀造安裝mysql」 3）安裝mtsql2： 「寶石安裝mysql2」

它應該工作。
