我正在尝试使用 gem 1.8.23、Ruby 1.9.2p318（2012-02-14 修订版 34678）[x86_64-darwin10.8.0]、MongoDB 1.6.2 和 MongoMapper 0.11.0 和 heroku 运行 Rails 3.2.3。我能够启动 rails 服务器并在开发和 heroku 上使用 mongoDB。但是每当我尝试安装任何新的东西（例如引导程序）或运行“rails s”命令时，我都会收到以下错误（粘贴在下面）。我认为它与 mongodb 和/或 mongo 映射器有关。我还附上了配置文件。几天以来我一直坚持这一点，任何提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。
错误：
new-host:talker Name$ rails g bootstrap:install
