好像它不能找到數據庫適配器。任何我dea如何解決這個問題？非常感謝

這裏是database.yml文件：

# SQLite version 3.x 
# gem install sqlite3 
# 
# Ensure the SQLite 3 gem is defined in your Gemfile 
# gem 'sqlite3' 

#============================================================================== 
Listings_development: 
    adapter: sqlite3 
    database: db/Listings.sqlite3 
    pool: 5 
    timeout: 5000 

# Warning: The database defined as "test" will be erased and 
# re-generated from your development database when you run "rake". 
# Do not set this db to the same as development or production. 
Listings_test: 
    adapter: sqlite3 
    database: db/Listings.sqlite3 
    pool: 5 
    timeout: 5000 

Listings_production: 
    adapter: sqlite3 
    database: db/Listings.sqlite3 
    pool: 5 
    timeout: 5000

下面是安裝寶石：由包包括

'bundle install'命令，確保已安裝所有寶石 – megas 2012-03-10 14:46:22

您的database.yml文件是什麼樣子的？並且你是否缺少數據庫連接器，用於你的開發環境中的默認設置？ – 2012-03-10 14:47:35

@Marc Talbot請參閱更新後的帖子。我已經在上面添加了database.yml文件。謝謝 – banditKing 2012-03-10 14:57:47

您需要一個名爲「開發」的環境，而不是「Listings_development」。重命名您的環境並再次嘗試啓動控制檯。

究竟是Listings_development：和Listings_production :.如果你嘗試啓動它，默認行爲是尋找開發：和生產：在你的分貝。這就是鐵軌所說的「約定配置」。名稱區分大小寫

服務器是否正常運行？
