RubyChina 的下载，MongoDB、Redis、Memcached 等的安装略过。

uninitialized constant BSON

下载后，bundle 好之后，ruby setup.rb时遇到如下问题：

ruby-china git:(master) ✗ >ruby setup.rb

Ruby China Successfully Installed.

看到了Ruby China Successfully Installed.我窃以为安装成功了，然后直接运行rails s，结果又报和上面一样的错误。日志如下：

ruby-china git:(master) ✗ >rails s

然后，搜问题解答，搜到如下解决方法： uninitialized constant BSON::ByteBuffer (Heroku) 安装所述，在Gemfile中，增加如下一行

gem "bson", "~> 2.2.0"

找不到合适版本的 moped

然后，运行运行bundle命令，但是却报如下错误：

ruby-china git:(master) ✗ >bundle
Fetching source index from http://ruby.taobao.org/
Resolving dependencies...
Bundler could not find compatible versions for gem "moped":
  In snapshot (Gemfile.lock):
    moped (1.5.0)

  In Gemfile:
    mongoid (>= 0) ruby depends on
      moped (~> 2.0.beta3) ruby

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.

找不到 frontier 分支

根据提示，我运行了bundle update命令，结果又报如下错误：

我查了一下 Grape 的 Github 页面，确实没有frontier的分支了。但是，不知道为什么 RubyChina 的Gemfiel文件中没有更新？

actionpack 依赖版本冲突

我把 Grape 的声明方式修改为gem 'grape'了，目前执行bundle update，但是却报如下错误：

ruby-china git:(master) ✗ >bundle update
Updating git://github.com/mongoid/mongoid.git
Updating git://github.com/huacnlee/bootstrap-helper.git
Updating git://github.com/searls/jasmine-rails.git

Resolving dependencies...
Bundler could not find compatible versions for gem "actionpack":
  In Gemfile:
    rails (= 4.0.2) ruby depends on
      actionpack (= 4.0.2) ruby

    actionpack-action_caching (= 1.0.0) ruby depends on
      actionpack (4.1.0.beta1)

环境

Ubuntu 12.04 32 位
ruby-2.0.0-p247
Rails 4.0.2
MongoDB shell version: 2.4.9
Redis 2.8.3
Memcached 1.4.13

问题列表

uninitialized constant BSON (NameError)--这个通过增加gem bson解决了；
Bundler could not find compatible versions for gem "moped"--提示bundle update，但是目前还没有跑通过。还要再看看；
fatal: ambiguous argument 'frontier': unknown revision or path not in the working tree.--这个通过直接引用gem 'grape'，而不是走 Github 分支，可以了；
Bundler could not find compatible versions for gem "actionpack"

求解答。
