Question

按照铁路指导说明here我收到错误：

/home/devname/.rvm/gems/ruby-2.3.1/gems/activerecord-5.0.0/lib/active_record/connection_adapters/postgresql_adapter.rb:675:in`scue in connect＆＃39 ;:致命：角色＆＃34; devname＆＃34;不存在

如果我尝试＆＃34; rails console development＆＃34;我也会得到这个。

这是我的database.yml（减去评论）：

default: &default
  adapter: sqlite3
  pool: 5
  timeout: 5000

development:
  <<: *default
  database: db/development.sqlite3

test:
  <<: *default
  database: db/test.sqlite3

production:
  <<: *default
 database: db/production.sqlite3

和我的gemfile：

source 'https://rubygems.org'   

gem 'rails',        '5.0.0'
gem 'puma',         '3.4.0'
gem 'sass-rails',   '5.0.5'
gem 'uglifier',     '3.0.0'
gem 'coffee-rails', '4.2.1'
gem 'jquery-rails', '4.1.1'
gem 'turbolinks',   '5.0.0'
gem 'jbuilder',     '2.4.1'

group :development, :test do
  gem 'sqlite3', '1.3.11'
  gem 'byebug',  '9.0.0', platform: :mri
end

group :development do
  gem 'web-console',           '3.1.1'
  gem 'listen',                '3.0.8'
  gem 'spring',                '1.7.2'
  gem 'spring-watcher-listen', '2.0.0'
end

group :production do
  gem 'pg', '0.18.4'
end

我很茫然，任何帮助都非常感激。
