我经常采取“旧”铁轨项目
我运行bundle install并使用json 1.8.0反对我，然后使用bundle update和bundle install
然后运行rake db:schema:load
当我运行rake db:seed时会出错：
ArgumentError：参数数量错误（给定1，预期为0）
我发现所有的seed.rb行并且只放了一个创建并且失败了同样的错误
同时打开控制台（rails控制台）并尝试使用不同型号创建两个
irb(main):002:0> Group.create( name: "Test" )
(0.5ms) BEGIN
(0.2ms) ROLLBACK
ArgumentError: wrong number of arguments (given 1, expected 0)

答案 0 :(得分：1)
根据@max评论的解决方案是：
从gem 'rails', '4.2.0.beta2'到gem 'rails', '4.2.7'
bundle update rails 问题解决了！
