無法安裝mysql2 gem OS X Mountain Lion

Question

我是RoR的新手，我正在嘗試安裝Mysql2 -v'0.3.11'。 我有OS X Mountain Lion，rails 3.2.6，ruby 1.9.3。

以下是我得到的錯誤。 我到處看，沒有找到任何東西。

$gem install mysql2 -v '0.3.11'

謝謝你的幫助。

Answer 1

您正在使用RVM而不是10.8附帶的Ruby。 好。 現在，停止使用10.8附帶的MySQL。

安裝和更新Homebrew 。 現在跑

brew install mysql

使用項目中的/Gemfile安裝mysql2 gem。 加

gem "mysql2"

到你的/Gemfile 。 然后通過運行使用Bundler更新您的應用程序

bundle install

讓包管理員（Homebrew和Bundler）為您服務。

這應該可以解決您遇到的問題。

Answer 2

正如Deefour所說，我不得不使用RVM。 回答他，我無法評論他的回答。 +1

但是rvm exec bundle install給了我一個錯誤：

rvm do bundle install被刪除了，使用rvm 1.9.2,1.9.3 do bundle install或者rvm all do bundle install而不是。

我使用sudo rvm all do bundle install ， sudo rvm all do bundle install它們都完美無缺。

Answer 3

我也在mac10.10中得到了相同類型的錯誤，並在下面用於我的命令中使用：

1. 使用以下命令安裝和升級Homebrew：

   brew安裝mysql

2. 運行使用以下命令安裝Mysql gem文件：

   gem install mysql2 -v'0.3.11'

3. 運行捆綁安裝
