我在安裝mysql2 gem時遇到問題。在Mac OSX上安裝用於Ruby on Rails的mysql2 gem 10.6
這來了,當我做gem install mysql2
:
Marks-MacBook-Pro:~ Mark$ gem install mysql2
Building native extensions. This could take a while...

而且當我使用這個rails server
出現:
Could not find gem 'mysql2 (>= 0, runtime)' in any of the gem sources listed in your Gemfile.
謝謝你!這工作!現在,當我啓動rails服務器並單擊「關於您的應用程序的環境...」時出現:Mysql2 ::錯誤 無法通過套接字'/tmp/mysql.sock'連接到本地MySQL服務器(2) Rails .root:/ Users/useruser/example你知道這意味着什麼嗎? – Maze 2011-03-23 21:12:10
你有沒有設置mysql服務器運行? 「mysql.server start」將完成這項工作,並且不要忘記爲root用戶配置訪問權限。 – ALoR 2011-03-23 21:21:34
這出現了:。錯誤!沒有更新文件,pid文件管理器退出。 – Maze 2011-03-23 22:57:49
