【问题描述】：
我最近做了一个“旧”的 Rails 项目
我运行 bundle install 并使用 json 1.8.0 给我错误，然后使用 bundle update 和 bundle install 修复它
然后运行rake db:schema:load
当我运行rake db:seed 时给出错误：
ArgumentError：参数数量错误（给定 1，预期 0）
我删除了seeds.rb 的所有行，只创建了一个，但同样的错误失败
同时打开一个控制台（rails 控制台）并尝试使用不同的模型创建两个并失败
irb(main):002:0> Group.create( name: "Test" )
(0.5ms) BEGIN
(0.2ms) ROLLBACK
ArgumentError: wrong number of arguments (given 1, expected 0)

如果您从堆栈跟踪的顶行通常会给出相关结果。
