这是我的流程
我尝试过的：
至于下面的BigDecimal，我已经卸载了，重新安装了gem。我还将 BigDecimal.new() 的使用更改为 BigDecimal()，如我在线研究时所示。

这个问题与这个问题
重复
我将把阿迪尔的答案放在下面。
根据 BigDecimal 的文档，对于所有 Ruby 版本 2.6.x，您应该使用具有特定版本的 BigDecimal：
各版本差异如下：
version characteristics Supported ruby version range 3.0.0 You can use BigDecimal with Ractor on Ruby 3.0 2.5 .. 2.0.x You cannot use BigDecimal.new and do subclassing 2.4 .. 1.4.x BigDecimal.new and subclassing always prints warning. 2.3 .. 2.7 1.3.5 You can use BigDecimal.new and subclassing without warning .. 2.5
尝试将其放入您的 gem 文件中。
gem 'bigdecimal', '~> 1.4'
or
gem 'bigdecimal', '1.3.5'
从 Ruby 3.2 升级到 Ruby 3.3 解决了这个问题和/或
