Ruby 未创建新项目

Question

我一直在尝试让 ruby 在轨道上启动测试应用程序 3 天。 我是个菜鸟，但我只是想让轨道运行。 我收到一个错误

Fetching nokogiri 1.10.9 (x64-mingw32)
Installing nokogiri 1.10.9 (x64-mingw32)
Gem::RuntimeRequirementNotMetError: nokogiri requires Ruby version >= 2.3, <
2.7.dev. The current ruby version is 2.7.1.83.
An error occurred while installing nokogiri (1.10.9), and Bundler cannot
continue.
Make sure that `gem install nokogiri -v '1.10.9' --source
'https://rubygems.org/'` succeeds before bundling.

In Gemfile:

Run `bundle install` to install missing gems.

任何帮助是极大的赞赏。 我卸载并重新安装了 4 次

该错误显示您需要执行的操作：

Gem::RuntimeRequirementNotMetError: nokogiri requires Ruby version >= 2.3, <
2.7.dev. The current ruby version is 2.7.1.83.

安装 ruby < 2.7 和 > 2.3，你有 2.7.1.83。
