Question

新手Ruby on Rails dev在这里。我最近从正在构建iPhone应用程序的远程团队中提取代码，包括用于Rails后端的API，但是一旦我完成了拉动代码，当我尝试启动Rails服务器时，我在终端中收到以下错误。

/usr/local/rvm/gems/ruby-1.9.3-p194@global/gems/bundler-1.1.5/lib/bundler/runtime.rb:68:in `require': can't convert true into String (TypeError)
   from /usr/local/rvm/gems/ruby-1.9.3-p194@global/gems/bundler-1.1.5/lib/bundler/runtime.rb:68:in `block (2 levels) in require'

这是application.rb：

require File.expand_path('../boot', __FILE__)

require 'rails/all'

if defined?(Bundler)
# If you precompile assets before deploying to production, use this line
Bundler.require(*Rails.groups(:assets => %w(development test)))
# If you want your assets lazily compiled in production, use this line
# Bundler.require(:default, :assets, Rails.env)
end

module Getlocal
class Application < Rails::Application
# Settings in config/environments/* take precedence over those specified here.
# Application configuration should go into files in config/initializers
# -- all .rb files in that directory are automatically loaded.

# Custom directories with classes and modules you want to be autoloadable.
config.autoload_paths += %W(#{config.root}/lib)

# Only load the plugins named here, in the order given (default is alphabetical).
# :all can be used as a placeholder for all plugins not explicitly named.
# config.plugins = [ :exception_notification, :ssl_requirement, :all ]

# Activate observers that should always be running.
# config.active_record.observers = :cacher, :garbage_collector, :forum_observer

# Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
# Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
# config.time_zone = 'Central Time (US & Canada)'

# The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
# config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
# config.i18n.default_locale = :de

# Configure the default encoding used in templates for Ruby 1.9.
config.encoding = "utf-8"

# Configure sensitive parameters which will be filtered from the log file.
config.filter_parameters += [:password]

# Enable escaping HTML in JSON.
config.active_support.escape_html_entities_in_json = true

# Use SQL instead of Active Record's schema dumper when creating the database.
# This is necessary if your schema can't be completely dumped by the schema dumper,
# like if you have constraints or database-specific column types
# config.active_record.schema_format = :sql

# Enforce whitelist mode for mass assignment.
# This will create an empty whitelist of attributes available for mass-assignment for all models
# in your app. As such, your models will need to explicitly whitelist or blacklist accessible
# parameters by using an attr_accessible or attr_protected declaration.
config.active_record.whitelist_attributes = true

# Enable the asset pipeline
config.assets.enabled = true

# Version of your assets, change this if you want to expire all your assets
config.assets.version = '1.0'
config.assets.initialize_on_precompile = false
end
end

以下是宝石文件：

end

  gem 'pry'
  gem 'pry-rails'
end

group :development do 
  gem 'better_errors'
  gem 'binding_of_caller'
  gem 'sextant'
end

不幸的是，错误是非常不明白的。我不确定这个问题对于SO来说是否足够具体。如果不是，请道歉，但在谷歌搜索几个小时后，阅读这样的线程：can't convert true into String和这一个：Ruby returns TypeError: can't convert Object into String，代码可识别，我想我是＆＃39; d看看我是否可以找人给我一些关于如何诊断并最终解决这个问题的更具体的建议。

非常感谢。

像往常一样，回答我的SO问题的最佳方法是完成提交问题的过程，坐在上面24小时然后再试一次。

这里的问题是＆＃34;休斯顿＆＃34;宝石，我不熟悉，似乎不适用于Ruby 1.9.3。有一次我用gem文件评论了这个gem（感谢Santosh建议我发布gem文件，因为这就是为什么我更深入地了解它！），Rails服务器一直启动。
