我正在以生产模式部署一个应用程序，但当我尝试完成此过程时，aways显示需要sqlite适配器，请有人知道如何停止此问题

我一直在使用RAILS\u ENV=production，但在本例中没有起作用

我看到的第一个问题是，您应该在命令的开头添加

RAILS\u ENV

声明，因为这将为命令的生命周期设置该变量

RAILS_ENV=production bundle exec rails generate admin_interface:setup

这可能是根本原因。（还要注意使用

bundle exec

，以确保正确加载Gemfile中指定的gemset）

如果要为shell设置它，请运行：

export RAILS_ENV=production

因此，您不必为每个命令手动设置它

第二种可能是数据库适配器配置不正确。如果这是RubyonRails应用程序，则数据库适配器在

config/database.yml

中定义。如果未指定，则可能默认为sqlite3。确保您有一个正确设置的database.yml文件

production:
  adapter: postgresql
  database: rails4_stack
  username: myusername
  password: mypassword
  pool: 5
  timeout: 5000
  encoding: utf8
  reconnect: false

我看到的第一个问题是，您应该将

RAILS\u ENV

声明放在命令的开头，因为这将为命令的生命周期设置该变量

RAILS_ENV=production bundle exec rails generate admin_interface:setup
