請告訴我們你是什麼操作系統，以及如何ÿ你安裝了Ruby，以便我們能夠更好地幫助你。 –

你需要確保你要使用被添加到您的Gemfile寶石：

gem 'sqlite3'

然後，安裝寶石，從應用程序根目錄下的命令行：

bundle install

這將導致它們被自動必需的，固定的錯誤：

no such file to load -- sqlite3

的錯誤是在輸出的最後一行：

no such file to load -- sqlite3

這表明它無法找到sqlite3文件。這可能是因爲沒有安裝sqlite3寶石。嘗試用這個命令來找到它：

gem list sqlite3

如果它不上來，用這個命令來安裝它：

gem install sqlite3

我想你可能已經安裝了Ruby的舊版本以及。我建議使用RVM並安裝較新版本的Ruby，比如1.9，而不是1.8。有關如何做到這一點的信息，請參閱this page。
