rbenv 工作但 ruby​​ 版本没有改变

Question

? rbenv version
system (set by /Users/eric.nguyen/.rbenv/version)
                                                                                                                                                             
? rbenv local 2.4.2
                                                                                                                                                           

? gem install bundler

? rbenv global 2.4.2
                                                                                                                                                           
? ruby -v

? rbenv version
2.4.2 (set by /Users/eric.nguyen/.ruby-version)

? gem -v
2.0.14.1

Ruby 版本仍然是 2.0.0p648

我使用的是 macOS Sierra 10.12.6。
我已经完成了这里提到的所有事情

我弄完了：

1. rbenv rehash
2. 放入eval "$(rbenv init -)"我的 .zshrc 和source ~/.zshrc
3. 放入$HOME/.rbenv/shims$PATH (/Users/eric.nguyen/.rbenv/shims:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/eric.nguyen/Library/Android /sdk/tools:/Users/eric.nguyen/Library/Android/sdk/platform-tools:/Users/eric.nguyen/.rbenv/shims)

但它仍然不会改变 ruby​​ 版本。
