當我執行上面的命令，我讓我的終端這個錯誤，錯誤運行「耙分貝：創建RAILS_ENV =‘發展’，」當發生
Deans-MacBook:depot dean$ rake db:create RAILS_ENV='development'
(in /Users/dean/src/RailsBook/depot) Couldn't create database for {"username"=>"root", "adapter"=>"mysql", "database"=>"depot_development", "host"=>"localhost", "password"=>nil}, charset: utf8, collation: utf8_unicode_ci (if you set the charset manually, make sure you have a matching collation)
在數據庫配置文件中，我有以下：
development:
adapter: mysql
database: depot_development
username: root
password:
host: localhost
我安裝了mysql gem，現在我不確定接下來要做什麼。我在Macbook上運行雪豹。有誰知道爲什麼這個錯誤發生？ 由於提前

在註釋中執行的命令，並得到如下：
Deans-MacBook:depot dean$ rake -t db:create RAILS_ENV='development'
(in /Users/dean/src/RailsBook/depot)
** Invoke db:create (first_time)
** Invoke db:load_config (first_time)
** Invoke rails_env (first_time)
** Execute rails_env
** Execute db:load_config
** Execute db:create
Couldn't create database for {"username"=>"root", "adapter"=>"mysql", "database"=>"depot_development", "host"=>"localhost", "password"=>nil}, charset: utf8, collation: utf8_unicode_ci (if you set the charset manually, make sure you have a matching collation)
EDIT 2 我已經卸載了MySQL寶石並重新安裝了它，我注意到一個錯誤發生在這裏它是：

我希望這有助於。
圍繞「發展」一詞不應該有引號。 – ryeguy 2010-05-19 17:51:11
你是在談論我什麼時候執行rake命令，如果是的話，我已經試過了，沒有引號，但仍然失敗。 – Dean 2010-05-19 17:53:42
你可以通過腳本/ dbconsole進入MySQL控制檯嗎？ – 2010-05-19 17:57:09
