这是我见过的最奇怪的错误。
我尝试使用应用服务器和远程数据库服务器部署rails。
我可以运行rails dbconsole并从应用服务器登录到数据库。
我也可以正常运行rake db:drop && rake db:create但是当我运行rake db:migrate时，所有地狱都会因为在处理迁移数据库之前从未见过的错误而丢失。我打赌这是一个我没有看到的简单修复，但请看看并告诉我我能解决这个问题。谢谢所有试过的人！
我可以在我的本地计算机上运行db：migrate并且它运行正常但是当我部署时我得到：
rake aborted!
ArgumentError: comparison of Fixnum with String failed
ArgumentError: comparison of Fixnum with String failed
ArgumentError: comparison of String with 0 failed
Tasks: TOP => db:migrate
(See full trace by running task with --trace)
然后我用跟踪运行它仍然没有给我任何想要修复它
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:migrate
rake aborted!

Face Palm。
我在我的环境文件中有这个并且导致了问题：
config.logger = Logger.new(STDOUT)
config.logger.level = 'DEBUG'
将config.logger.level = 'DEBUG'更改为config.log_level = 'DEBUG'
一切都很顺利。
