Ruby on rails Rails 4：从内到外了解bundler

我正在开发一个Rails4应用程序，我将所有gems本地化到：vendor/gems文件夹

完成此操作后，我的应用程序中有一个名为：.bundle的文件夹，其中包含配置文件

# Content inside config file
---
BUNDLE_PATH: vendor/gems
BUNDLE_DISABLE_SHARED_GEMS: '1'

后来，我意识到，我不想本地化Gemfile中的每个gem。我希望我的应用程序使用系统中可以定义的少量gem，以及供应商/gems文件夹中的少量gem

要做到这一点：

我删除了.bundle文件夹 已删除Gemfile.lock 打开Gemfile并进行以下修改并运行bundle安装：

我明白了：

Fetching gem metadata from https://rubygems.org/...........
Resolving dependencies...
Installing mysql2 0.3.17
Using rails 4.1.8 from source at vendor/gems
Using uglifier 2.5.3 from source at vendor/gems
Using bundler 1.6.5
Your bundle is complete!
Use `bundle show [gemname]` to see where a bundled gem is installed.

当我查看Gemfile.lock时，我看到：

PATH
  remote: vendor/gems
  specs:
    uglifier (2.5.3)

PATH
  remote: vendor/gems
  specs:
    rails (4.1.8)

GEM
  remote: https://rubygems.org/
  specs:
    mysql2 (0.3.17)

PLATFORMS
  ruby

DEPENDENCIES
  mysql2 (= 0.3.17)
  rails (= 4.1.8)!
  uglifier (= 2.5.3)!

{PATH_TO_APP} $bundle show mysql2
-> /home/pp/.rvm/gems/ruby-1.9.3-p547/gems/mysql2-0.3.17

我注意到rails=4.1.8&uglifier=2.5.3无法找到合适的路径

为了改变这一点，我再次打开了我的GEM文件，并将代码更改为：

source 'https://rubygems.org'
gem 'rails', '4.1.8', path: "vendor/gems/ruby/1.9.1"
gem 'mysql2', '0.3.17' # Use mysql as the database for Active Record
gem 'uglifier', '2.5.3', path: "vendor/gems/ruby/1.9.1" # Use Uglifier as compressor for JavaScript assets

当我再次尝试运行bundle安装时，我发现以下跟踪：

activerecord at /home/pp/Workspace/MyProject/vendor/gems/ruby/1.9.1/specifications did not have a valid gemspec.
This prevents bundler from installing bins or native extensions, but that may not affect its functionality.
The validation message from Rubygems was:
  ["README.rdoc"] are not files
Using activerecord 4.1.8 from source at vendor/gems/ruby/1.9.1
Using bundler 1.6.5
Using execjs 2.2.2 from source at vendor/gems/ruby/1.9.1
Using hike 1.2.3 from source at vendor/gems/ruby/1.9.1
Using multi_json 1.10.1 from source at vendor/gems/ruby/1.9.1

mysql2 at /home/pp/Workspace/MyProject/vendor/gems/ruby/1.9.1/specifications did not have a valid gemspec.
This prevents bundler from installing bins or native extensions, but that may not affect its functionality.
If you need to use this package without installing it from a gem repository, please contact seniorlopez@gmail.com and ask them to modify their .gemspec so it can work with `gem build`.
The validation message from Rubygems was:
  ["ext/mysql2/extconf.rb"] are not files
Using mysql2 0.3.17 from source at vendor/gems/ruby/1.9.1

并从Gemfile.lock进行跟踪

这里发生了三件事：

依赖项仍然不满足。 mysql2，而不是从系统中挑选，bundler是从供应商/gems中挑选的 activerecord和其他gem的警告消息

---

我被卡住了，想知道，实现这种行为的最佳方式是什么。我是遗漏了什么还是遵循了正确的方法？

为什么要将所有gem本地化到供应商文件夹中？我建议创建自己的。并更改Gem文件中的源路径，我希望它能工作。

感谢@Lareb提供的解决方案。然而，由于一些限制，我不能选择拥有自己的GemServer。第一：因为，GemServer需要自己的端口，例如localhost:9292。即使我们设法在所需的端口上运行它，稍后，托管团队内部也可以阻止此端口。我在这里看到过类似的问题。第二个限制：有一些gem是所有应用程序（如mysql2等）所共有的。这些gem位于所有应用程序都可以访问的共享路径上，因此我可能必须在Gemfile中定义各种源。我知道这不是一个大挑战，可以找到解决办法。但是现在你已经看到了这一点，你的看法是什么？
