tl;博士：升级sinatra到版本2.1.0。（或者，将 ruby​​ 降级为v2.7.）

您正在使用最新版本的 ruby​​ ( ) 运行旧的 gem 版本（特别是）。这样做你可能会遇到各种兼容性问题，因为你可能会从这些库中丢失关键的 ruby​​ 3.0 兼容性更新。sinatra v2.0.3v3.0.0

变更日志中多次提到ruby​​ 2.7+ 关键字弃用修复sinatra。

具体来说，这个错误：

gems/3.0.0/gems/sinatra-2.0.3/lib/sinatra/base.rb:1629:in `compile!'

此 PR中的此更改已修复，该更改作为 sinatra 的一部分提供。此外，作为发行版的一部分，还添加了其他修复。v2.0.8v2.1.0
