未能安装bundle ruby版本管理器

我以前从没试过鲁比。我在试着运行这个 elixirschool github repo .

我第一次收到这个错误信息。

$ bundle install  
Your Ruby version is 2.5.1, but your Gemfile specified ~> 2.3.7

所以我遵循问题的指示。 How to fix "Your Ruby version is 1.9.3, but your Gemfile specified 2.0.0"

现在我收到这个消息了。

$ bundle install  
Traceback (most recent call last):  
    1: from /usr/local/bin/bundle:23:in `<main>'
/usr/local/bin/bundle:23:in `load': cannot load such file -- /usr/local/lib/ruby/gems/2.5.0/gems/bundler-1.16.1/exe/bundle (LoadError)

我也做了这个命令。

$ bundler install
