MongoDB连接错误，当我尝试安装任何宝石

我想运行使用gem 1.8.23，Ruby 1.9.2p318（2012-02-14修订版34678）的Rails 3.2.3 [x86_64-darwin10.8.0]，MongoDB 1.6.2与MongoMapper 0.11.0和heroku。我能够在开发和heroku上启动rails服务器并使用mongoDB。但每当我尝试安装新的东西（例如bootstrap）或运行'rails s'命令时，我会收到以下错误（粘贴在下面）。我认为它与mongodb和/或mongo映射器有关。我也附上了配置文件。自从几天以来，我一直坚持这一点，任何暗示或想法都受到高度赞赏。不幸的是，这是我的第一个RoR应用程序，因此我可能听起来很愚蠢。MongoDB连接错误，当我尝试安装任何宝石

它肯定无法连接到MongoDB。 MongoDB在运行吗？该行MongoMapper.connect（Rails.env）是它失败的地方。 – 2012-04-25 15:45:51

我可以浏览到localhost：28017并查看所有...不明白为什么它会抛出错误.. – xoail 2012-04-25 18:26:33

您的配置文件中说，连接到本地主机：28017，但是这是Web控制台。你可能想要localhost：27017。

我也试过了...我得到/Users/Name/.rvm/rubies/ruby-1.9。 2-p318/lib/ruby/1.9.1/uri/common.rb：156：在split中：坏URI（不是URI？）：（URI :: InvalidURIError） – xoail 2012-04-25 19:38:55

需要'mongodb：// localhost： 27017' – 2012-04-25 19:50:30

是...试过这个{'uri'=> ENV ['MONGOHQ_URL'] || 'mongodb：// localhost：27017'}，我得到了错误的URI错误。 – xoail 2012-04-25 19:52:14
