Question

我正在使用ruby和sinatra与activerecord和rake（没有rails）。我的db目录中有以下config.yml文件（我省略了生产）。

config.yml

rake aborted!

Tasks: TOP => db:setup => db:schema:load_if_ruby => db:create
(See full trace by running task with --trace)

当我运行rake db：create或rake db：setup时，我收到以下错误：

# Rakefile

require './app'
require 'sinatra'
require 'active_record'
require 'sinatra/activerecord/rake'
#require 'rake'

Rake文件：

source 'https://rubygems.org'


gem "sinatra"
gem "activerecord"
gem "sinatra-activerecord"
gem 'sinatra-flash'
gem 'sinatra-redirect-with-flash'
gem 'rake'

group :development do
 gem 'sqlite3'
 gem "tux"
end

group :production do
 gem 'sqlite3'
end

的Gemfile ：

TCPBasicClientApp::socketDataArrived()
