耙子流产了! PG :: ConnectionBad:fe_sendauth:没有提供密码任务:TOP => db:migrate(通过使用--trace运行任务来查看完整跟踪)

标签: ruby-on-rails postgresql heroku ruby-on-rails-4

尝试rake db:migrate

时,我得到以下信息
rake aborted!
PG::ConnectionBad: fe_sendauth: no password supplied

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

转到我的localhost时,我也收到类似的消息

fe_sendauth: no password supplied

我的rails服务器和rails控制台无法正常工作

我一直在尝试一些事情,这就是我的gemfile目前的样子:

source 'https://rubygems.org'
ruby '2.0.0'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.3'

# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.0'

# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'

# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '~> 4.0.0'

# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', platforms: :ruby

# Use jquery as the JavaScript library
gem 'jquery-rails'

# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'

# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 1.2'
gem 'devise'


gem 'pg'

group :doc do
  # bundle exec rake doc:rails generates the API under doc/api.
  gem 'sdoc', require: false
end


group :production do
  gem 'rails_12factor'
end

和我的database.yml

development:
  adapter: postgresql
  encoding: unicode
  database: myapp_development
  pool: 5
  username: myapp
  password:

test:
  adapter: postgresql
  encoding: unicode
  database: myapp_test
  pool: 5
  username: myapp
  password:

production:
  adapter: postgresql
  encoding: unicode
  database: myapp_production
  pool: 5
  username: myapp
  password:

有什么问题?似乎要在本地访问我的postgres表我需要某种密码?通过Heroku运行我的应用程序正常。所以我只是打开Heroku,我可以提交新的链接和帖子,因为我的应用程序是有意的,但它不会在本地工作。

对于您的本地计算机,在test的{​​{1}}和development部分下,您应该将database.yml更改为您登录的用户名。 rails生成器使其与应用程序名称相同 - 这不起作用。对于生产而言,它无关紧要,因为它在Heroku上运行,并且在部署时会自动更改该设置。

您应该根据任何现有的值来设置 username password 的值。您可以先依次使用psql -d postgres\du
