ruby-on-rails - 找不到 gem bundler Ruby

Question

使用 Mac OS 13，rbenv。

ruby 2.5.0p0 (2017-12-25 revision 61468) [x86_64-darwin17]

Rails 5.1.4

Bundler version 1.16.1

rbenv 1.1.1

我正在尝试启动一个新的 Rails 应用程序，然后得到这个:

据我了解，这与 Ruby 版本有关，但我不知道如何解决该问题。

看起来您可能需要执行gem install bundler并获取 bundler gem才能启动并运行rails。
