ruby-on-rails-4 - rails 4 部署 - rake stderr : config.eager_load 设置为 nil .. 不正确的错误消息

Question

在使用 Capistrano 进行项目暂存部署期间，为了解决常见的数据库访问错误，我注意到 rake stderr 行:

  rake stderr: config.eager_load is set to nil. Please update your config/environments/*.rb files accordingly..

但是，我的 config/environments/*rb 文件已根据需要正确设置..
为什么这个消息？我错过了什么？

我的配置/环境/development.rb

 config.eager_load = false

我的配置/环境/production.rb

 config.eager_load = true

我的配置/环境/test.rb

config.eager_load = false

这是控制台日志的摘录

    Tasks: TOP => db:migrate
    (See full trace by running task with --trace)

    SSHKit::Command::Failed: rake exit status: 1
    rake stdout: Nothing written
    rake stderr: config.eager_load is set to nil. Please update your config/environments/*.rb files accordingly:

      * development - set it to false
      * test - set it to false (unless you use a tool that preloads your test environment)
      * production - set it to true

    rake aborted!
    Mysql2::Error: Access denied for user 'root'@'localhost' (using password: NO)

部署时我遇到了类似的问题

cap staging deploy

问题是 capistrano 正在寻找数据库 myapp_staging , 而我需要 myapp_production .

我通过添加修复它

set :stage, "production"

在 config/deploy/staging.rb .
