我的rails应用程序中有有效的config/credentials.yml.enc和master.key。因为我在本地计算机上使用RAILS_ENV='production'尝试了rails命令，即rails db：create，rails db：migrate等。
我已经在我的ubuntu服务器上的/ app_name / shared / config /中添加了master.key文件。但是仍然遇到这个问题。
答案 0 :(得分：0)
您需要添加
SECRET_KEY_BASE = 'Your_SECRET_KEY_BASE'
来做环境！
我遇到了同样的问题。相信我，关注https://blog.xuite.net/yhunglee/blog/585116240-Problems+of+deploying+rails+5.2.0+to+production 可以解决这个问题。
