Rails：无法连接PostgreSQL数据库

Question

这是我的database.yml：

production:
<<: *default
database: skilltracker_production
username: skilltracker
password: <%= ENV['SKILLTRACKER_DATABASE_PASSWORD'] %>

当我运行bundle exec rake db:create:all时，收到以下错误消息： fe_sendauth: no password supplied

[...]

Couldn't create database for {"adapter"=>"postgresql", "encoding"=>"unicode", "pool"=>5, "database"=>"skilltracker_development", "host"=>"localhost"} FATAL: Peer authentication failed for user "skilltracker"

[...]

Couldn't create database for {"adapter"=>"postgresql", "encoding"=>"unicode", "pool"=>5, "database"=>"skilltracker_development", "username"=>"skilltracker", "password"=>"skilltracker"}

[...]

Couldn't create database for {"adapter"=>"postgresql", "encoding"=>"unicode", "pool"=>5, "database"=>"skilltracker_production", "username"=>"skilltracker", "password"=>nil}

有什么理想吗？谢谢你的帮助！

完整性检查：您是否实际将密码存储在该环境变量中？尝试在该字段中对其进行硬编码，作为故障排除步骤。
