Question

我在Heroku的“app startup”上遇到了这个错误。在localhost上一切正常。

app.rb （Sinatra）

require 'uri'
require 'sinatra'
require 'mongo'
require "bson"
require 'chartkick'
require 'omniauth-facebook'

include Mongo

use Rack::Session::Cookie
use OmniAuth::Builder do
    provider :facebook, "KEY", "SECRET", :scope => 'read_stream'
end

#### DATABASE #######
def get_connection
  return @db_connection if @db_connection
  db = URI.parse(ENV['MONGOHQ_URL'] || 'mongodb://localhost/facebook')
  db_name = db.path.gsub(/^\//, '')
  @db_connection = Mongo::Connection.new(db.host, db.port).db(db_name)
  @db_connection.authenticate(db.user, db.password) unless (db.user.nil? || db.user.nil?)
  @db_connection
end

db = get_connection

的Gemfile

source 'https://rubygems.org'
ruby '2.0.0'

gem 'mongo'
gem "bson"
gem 'bson_ext'
gem "sinatra"
gem "koala", "~> 1.7.0rc1"
gem "chartkick"
gem 'omniauth-facebook'

config.ru

require './app'
run Sinatra::Application

Answer 1

日志显示名称错误。我建议你指定正确的范围。 Rails有一种非常复杂的查找常量的方法。我建议你看看这个：

和这个

Answer 2

看起来你使用的Mongo是1.3.1而BSON可能是2.0。这些似乎并不合作。我试着将1.9 BSON放在那里，看看是否有效。

您可以添加以下内容： gem“bson”，“〜＆gt; 1.9.2”

到您的Gemfile。

希望有帮助吗？
