我在使用Rails 4.2.6的Ruby 2.3.1时出现了堆栈级别太深的错误。 我该如何解决这个问题？
在执行以下命令时，出现错误。
heroku run rails db:migrate
这是错误。
Tasks: TOP => db:migrate => environment

我将Rails版本从4.2.6更新到了4.2.8。但仍然有同样的问题。
甚至，heroku运行bundle exec rake db:migrate也不起作用。
无法理解为什么仍然存在此错误。 有人帮我吗？
答案 0 :(得分：0)
我已删除此错误。 生产的红宝石版本为2.5.0，这是不合适的。 我的版本下降到2.4.5。从2.5.0版开始，那么它可以正常工作。
