Question

我试图在Kubuntu 12.04中使用ruby和sinatra在本地设置facebook应用程序。我在我的gemfile中包含了以下gems。我在我的系统中安装了postgresql，我可以运行postgresql命令行并运行基本命令如createdb，create table等。

gem "sinatra"
gem "koala"
gem "json", "1.5.5"
gem "httparty"
gem "thin"
gem "rack", "1.3.10"
gem "pg"
gem "activerecord"
gem "sinatra-activerecord"

在我的app.rb文件中添加了这些文件，

require "rubygems"
require "sinatra"
require "sinatra/activerecord"
require "koala"
require "./config/environment" #database configuration

运行

rake -T

在我的终端

给了我以下错误。

rake aborted!

任何人都可以帮忙。谢谢。

正如@iain所提到的，这是由于config / database.yml文件中的解析错误。检查它是否是有效的语法，并用空格替换任何选项卡。

Rake任务不使用postgresql和sinatra-activerecord
