Ruby版本仍然是2.0.0p648

我在macOS Sierra 10.12.6上 .
我做了所有提到的事情here

我弄完了：

  • rbenv rehash

  • 把 eval "$(rbenv init -)" 放在我的.zshrc和 source ~/.zshrc 中

  • 将 $HOME/.rbenv/shims 放入$ 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）

但它仍然没有改变ruby版本 .

    在使用rbenv安装新的ruby版本之后以及安装具有命令行选项的gem时，总是需要运行 rbenv rehash

    重新启动计算机可以解决此问题 .
