警告：'/Library/Ruby/Gems/1.8/specifications/rack-1.3.5.gemspec'中的無效.gemspec格式

我想運行一個Sinatra應用程序，並且因爲沒有找到機架而失敗。我收到以下錯誤：警告：'/Library/Ruby/Gems/1.8/specifications/rack-1.3.5.gemspec'中的無效.gemspec格式

WARNING: Invalid .gemspec format in '/Library/Ruby/Gems/1.8/specifications/rack-1.3.5.gemspec'

我正在運行的Ruby版本1.8.6

我試圖刪除文件gemspec運行寶石重新安裝。當我安裝機架時，它會成功無誤。
