我最近在我的机器上升级了mysql。因此，我正在尝试相应地更新我的 mysql2 gem。在此过程中，我运行“bundle install”，由于某种原因，我的 Gemfile 中的所有 gem 都安装在 ./mysql2 目录中？
ruby-1.9.2-p180 [dev]:project.git$ bundle install

Your bundle is complete! It was installed into ./mysql2
由于某种原因，我的 .bundle 目录还包含一个配置文件，表明 BUNDLE_PATH 是 mysql2？我不知道它从哪里来，也不知道它是如何到达那里的......

BUNDLE_DISABLE_SHARED_GEMS: "1"
BUNDLE_PATH: mysql2
这是我的 Gemfile：
source 'http://rubygems.org'
gem 'rake'
gem 'rails'
gem 'mysql2', '0.2.6'
gem 'legacy_data'
gem 'htmlentities'
gem 'httparty'
gem 'net-ssh'
gem 'net-sftp'
gem 'rsolr'
gem 'activerecord-import'
gem 'ar-extensions'
gem 'typhoeus'
gem 'composite_primary_keys'
gem 'devise'
gem 'authlogic'
gem 'will_paginate'
gem 'json_pure' # Note that installing the 'json' gem results in a "[BUG] unknown type 0x22 (0xc given)" error when loading rails console
gem "friendly_id", "~> 3.2.1"
# Use unicorn as the web server
# gem 'unicorn'
# Deploy with Capistrano
# gem 'capistrano'
# To use debugger (ruby-debug for Ruby 1.8.7+, ruby-debug19 for Ruby 1.9.2+)
# gem 'ruby-debug'
# gem 'ruby-debug19'
# Bundle the extra gems:
# gem 'bj'
# gem 'nokogiri'
# gem 'sqlite3-ruby', :require => 'sqlite3'
# gem 'aws-s3', :require => 'aws/s3'
# Gems for RSpec
# Bundle gems for the local environment. Make sure to
# put test-only gems in this group so their generators
# and rake tasks are available in development mode:
group :search_development, :test do
gem 'rspec-rails', "~> 2.4"
gem 'webrat'
gem 'rspec'
end
gem 'autotest'
我已经在这方面投入了一段时间了。提前感谢您提供有关如何继续的任何想法或想法。 （另外，这是我第二次将捆绑安装到 mysql2 目录中，所以我决定在挖更深的洞之前停止）
