ruby-on-rails - Gem::InstallError: ruby​​zip 需要 Ruby 版本 >= 2.4

Question

我在 rails 上安装 ruby​​ 时遇到了这个错误。它说它需要 Ruby 版本 >= 2.4，我不太明白我应该如何解决这个问题。我下载了 railsinstaller 包，里面的 ruby​​ 是 2.3.3 版。我目前正在关注 https://www.youtube.com/watch?v=3D9d0wmwHVQ 的教程但是视频没有说明我在这里遇到的问题。任何人都可以给我一些建议吗？
谢谢!

Make sure that `gem install rubyzip -v '2.0.0'` succeeds before bundling.

In Gemfile:

迪帕克已经在他的回答中写了如何解决这个问题。但我认为使用不同的方法可能会更好。

来自 RailsInstaller 的版本有一个大问题.它们都是过时的，安装的 Ruby 和 Ruby on Rails 版本已经报废。我建议根本不要使用 RailsInstaller。

建议关注官方Ruby Documentation about Installation并使用 RubyInstaller安装 Ruby。之后，只需安装最新的 Ruby on Rails gem

gem install bundler
gem install rails

从你的命令行。
