我在 Heroku 上的“应用程序启动”时收到此错误。在本地主机上一切正常。

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

看起来您使用的 Mongo 是 1.3.1，而 BSON 可能是 2.0。这些似乎不能一起工作。我会尝试将 1.9 BSON 放在那里，看看是否可行。

您可以通过添加：gem "bson", "~> 1.9.2"

到您的 Gemfile。

希望有帮助吗？

日志说它是一个名称错误。我建议您指定正确的范围。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
