我的本地环境是

localdev:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: tibcodocs_development
  pool: 5
  username: root
  password: root
  host: localhost

您应该在正确的环境中启动您的 rails 应用程序。

RAILS_ENV=localdev bundle exec rails g model language name:string -e localdev

（如果 localdev 不是您的开发模式，或者类似的东西）

目前它看起来像生产设置，因为您的应用程序尝试联系亚马逊云或类似的东西（jivestaging.cxrwdp0ae112.us-east-1.rds.amazons.com）。

视窗版本：

set RAILS_ENV=localdev
bundle exec rails g model language name:string
