从rvm切换到rbenv，现在无法使用rails s。 无法激活bundler-1.12.5，已经激活了bundler-1.13.0.rc.1（Gem :: LoadError）
第一个错误：
`check_version_conflict': can't activate bundler-1.12.5, already activated bundler-1.13.0.rc.1 (Gem::LoadError) 陷入这个错误：
/Users/phillipjones/workspace/messengerApp/vendor/bundle/gems/sqlite3-1.3.11/lib/sqlite3.rb:6:in `require': dlopen(/Users/phillipjones/workspace/messengerApp/vendor/bundle/gems/sqlite3-1.3.11/lib/sqlite3/sqlite3_native.bundle, 9): Library not loaded: /Users/phillipjones/.rvm/rubies/ruby-2.3.1/lib/libruby.2.3.0.dylib (LoadError) Referenced from: /Users/phillipjones/workspace/messengerApp/vendor/bundle/gems/sqlite3-1.3.11/lib/sqlite3/sqlite3_native.bundle Reason: image not found - /Users/phillipjones/workspace/messengerApp/vendor/bundle/gems/sqlite3-1.3.11/lib/sqlite3/sqlite3_native.bundle
以下是导致此问题的情况以及我尝试解决的步骤：
从rvm切换到rbenv后，我遇到了使用rvm创建的应用程序的问题。 我无法运行rails s。
首先我得到了这个错误：
Phillip-Joness-MacBook:messengerApp phillipjones$ rails s /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/specification.rb:2274:in `check_version_conflict': can't activate bundler-1.12.5, already activated bundler-1.13.0.rc.1 (Gem::LoadError) from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/specification.rb:1403:in `activate' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_gem.rb:68:in `block in gem' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_gem.rb:67:in `synchronize' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_gem.rb:67:in `gem' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/bundler-1.13.0.rc.1/lib/bundler/postit_trampoline.rb:32:in `' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/bundler-1.13.0.rc.1/lib/bundler/setup.rb:2:in `' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/phillipjones/workspace/messengerApp/config/boot.rb:3:in `' from /Users/phillipjones/workspace/messengerApp/bin/rails:8:in `require_relative' from /Users/phillipjones/workspace/messengerApp/bin/rails:8:in `' from /Users/phillipjones/workspace/messengerApp/vendor/bundle/gems/spring-1.7.1/lib/spring/client/rails.rb:28:in `load' from /Users/phillipjones/workspace/messengerApp/vendor/bundle/gems/spring-1.7.1/lib/spring/client/rails.rb:28:in `call' from /Users/phillipjones/workspace/messengerApp/vendor/bundle/gems/spring-1.7.1/lib/spring/client/command.rb:7:in `call' from /Users/phillipjones/workspace/messengerApp/vendor/bundle/gems/spring-1.7.1/lib/spring/client.rb:30:in `run' from /Users/phillipjones/workspace/messengerApp/vendor/bundle/gems/spring-1.7.1/bin/spring:49:in `' from /Users/phillipjones/workspace/messengerApp/vendor/bundle/gems/spring-1.7.1/lib/spring/binstub.rb:11:in `load' from /Users/phillipjones/workspace/messengerApp/vendor/bundle/gems/spring-1.7.1/lib/spring/binstub.rb:11:in `' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/phillipjones/workspace/messengerApp/bin/spring:13:in `' from bin/rails:3:in `load' from bin/rails:3:in `'
然后我尝试了捆绑更新。 没有变化，所以我尝试安装bundler gem：
Phillip-Joness-MacBook:messengerApp phillipjones$ gem install bundler Successfully installed bundler-1.12.5 Parsing documentation for bundler-1.12.5 Done installing documentation for bundler after 5 seconds 1 gem installed
没变。
我试图安装确切的捆绑版本
Phillip-Joness-MacBook:messengerApp phillipjones$ gem install bundler-1.12.5 ERROR: Could not find a valid gem 'bundler-1.12.5' (>= 0) in any repository
没变。
我自制安装了rbenv-bundler
hillip-Joness-MacBook:rubygems phillipjones$ brew install rbenv-bundler ==> Downloading https://github.com/carsomyr/rbenv-bundler/archive/0.99.tar.gz ==> Downloading from https://codeload.github.com/carsomyr/rbenv-bundler/tar.gz/0.99 ######################################################################## 100.0% 🍺 /usr/local/Cellar/rbenv-bundler/0.99: 13 files, 46.6K, built in 10 seconds
再次安装了bundler，删除了gemlock.file并运行了bundle install

然后我检查了rbenv本地。 做了rbenv rehash。 检查了耙子。 并再次尝试过rails。 这次我收到了一个新错误：
Phillip-Joness-MacBook:messengerApp phillipjones$ rbenv local ruby-2.3.1 Phillip-Joness-MacBook:messengerApp phillipjones$ rbenv rehash Phillip-Joness-MacBook:messengerApp phillipjones$ rbenv which rake /Users/phillipjones/.rbenv/versions/2.3.1/bin/rake Phillip-Joness-MacBook:messengerApp phillipjones$ rails ss /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/specification.rb:2274:in `check_version_conflict': can't activate bundler-1.12.5, already activated bundler-1.13.0.rc.1 (Gem::LoadError) from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/specification.rb:1403:in `activate' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_gem.rb:68:in `block in gem' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_gem.rb:67:in `synchronize' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_gem.rb:67:in `gem' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/bundler-1.13.0.rc.1/lib/bundler/postit_trampoline.rb:32:in `' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/bundler-1.13.0.rc.1/lib/bundler/setup.rb:2:in `' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/phillipjones/workspace/messengerApp/config/boot.rb:3:in `' from /Users/phillipjones/workspace/messengerApp/bin/rails:8:in `require_relative' from /Users/phillipjones/workspace/messengerApp/bin/rails:8:in `' from /Users/phillipjones/workspace/messengerApp/vendor/bundle/gems/spring-1.7.2/lib/spring/client/rails.rb:28:in `load' from /Users/phillipjones/workspace/messengerApp/vendor/bundle/gems/spring-1.7.2/lib/spring/client/rails.rb:28:in `call' from /Users/phillipjones/workspace/messengerApp/vendor/bundle/gems/spring-1.7.2/lib/spring/client/command.rb:7:in `call' from /Users/phillipjones/workspace/messengerApp/vendor/bundle/gems/spring-1.7.2/lib/spring/client.rb:30:in `run' from /Users/phillipjones/workspace/messengerApp/vendor/bundle/gems/spring-1.7.2/bin/spring:49:in `' from /Users/phillipjones/workspace/messengerApp/vendor/bundle/gems/spring-1.7.2/lib/spring/binstub.rb:11:in `load' from /Users/phillipjones/workspace/messengerApp/vendor/bundle/gems/spring-1.7.2/lib/spring/binstub.rb:11:in `' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/phillipjones/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/phillipjones/workspace/messengerApp/bin/spring:13:in `' from bin/rails:3:in `load' from bin/rails:3:in `'
gem env # to check that everything was pointing at 1.9 and not the system gem install --no-ri --no-rdoc bundler rbenv rehash # necessary to load up the bundle executable bundle --path=vendor/bundle
rbenv rehash和gem install --no-ri --no-rdoc bundler应该能够解决这个问题。 尝试上面的代码，它应该解决您的问题。
您的特定版本安装引入了捆绑程序中的版本冲突
gem install bundler-1.12.5
