在rbenv上安裝mysql gem

我試圖在MAC OSX機器上使用vagrant。我使用SSH連接了流浪漢，並設置了ruby 1.9.2-p290。現在我嘗試安裝ruby gems，但是我想要安裝mysql2 gem時遇到了這個問題。在rbenv上安裝mysql gem

Gem files will remain installed in /home/vagrant/.rbenv/versions/1.9.2-p290/lib/ruby/gems/1.9.1/gems/mysql-2.8.1 for inspection.

我在寶石文件中設置

gem 'mysql2'

我再次運行bundle命令，但結果是一樣的。

爲什麼mysql不能在vagrant上運行？

mysql2 gem具有針對mysql二進制文件構建的本地C擴展。你的流浪者機器需要安裝mysql。做這樣的事情

$ vagrant ssh 
$ sudo apt-get install mysql-server mysql-client

MySQL已安裝後，你應該能夠安裝mysql2寶石。

編輯：您還需要mysql開發庫，以便

$ sudo apt-get install libmysqlclient-dev libmysqlclient16 ruby-dev
