升級到 Ruby 3.0.5
Ruby 3.0 帶來了一些重大變化，這會為使用大量 gem 的典型 rails 應用程式帶來很多麻煩，尤其是關鍵字參數行為的重大變化和 URI.escape 方法的刪除。
關鍵字參數行為改變
- Ruby 3 之前
irb(main):001:0> RUBY_VERSION
=> "2.7.6"
irb(main):002:1* def add(a: 1, b: 2)
irb(main):003:1* sum = a + b
irb(main):004:1* puts "#{a} + #{b} = #{sum}"
irb(main):005:0> end
=> :add
irb(main):006:0> add({a: 10, b: 20})
10 + 20 = 30
=> nil- Ruby 3 之後
irb(main):001:0> RUBY_VERSION
=> "3.0.5"
irb(main):002:1* def add(a: 1, b: 2)
irb(main):003:1* sum = a + b
irb(main):004:1* puts "#{a} + #{b} = #{sum}"
irb(main):005:0> end
=> :add
irb(main):006:0> add({a: 10, b: 20})
