我有一个奇怪的问题。当我尝试 ro makerails s时，它​​说我：

我无法理解的是，昨天一切正常！今天早上，Windows 更新了，所以也许有一个链接，不是吗？

此外，我无法访问，localhost:3000但我可以连接到 PhpMyAdmin 的登录页面（在写入我的登录名/密码后它拒绝我的连接）：localhost:81

在写这篇文章之前我找到了一些解决方案，但没有人为我工作！

提前致谢。

更新

这是我的 db.yml ：

# And be sure to use new-style password hashing:
#   http://dev.mysql.com/doc/refman/5.0/en/old-client.html
development:
  adapter: mysql
  encoding: utf8
  reconnect: false
  database: acturevue_development
  pool: 5
  username: root
  password: password
  host: localhost

更新 Gemfile 以查看 gem 是否可能是问题所在：

    source 'http://rubygems.org'

gem 'rails', '3.2.8'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'mysql'



# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

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

  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'

# To use Jbuilder templates for JSON
# gem 'jbuilder'

# Use unicorn as the app server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger
# gem 'debugger'


gem 'geocoder'
gem 'gmaps4rails'
gem "bootstrap-sass", ">= 2.1.0.0"

gem "rolify", ">= 3.2.0"
gem "simple_form", ">= 2.0.3"
gem "paperclip", "~> 3.0"

您必须为 mysql 指定 sockect

development:
 adapter: mysql
 encoding: utf8
 reconnect: false
 database: acturevue_development
 pool: 5
 username: root
 password: password
 host: localhost
 socket: /opt/lampp/var/mysql/mysql.sock //this path must point to your mysql socket

ps 你需要在Linux和Windows下都指定这个选项，在Mac OS下不完全确定。

试试下面的。

在宝石文件中

宝石'mysql'，'2.8.1'

在数据库.yml

发展：

adapter: mysql
 encoding: utf8
  reconnect: false
  database: acturevue_development
  pool: 5
  username: root
 password: password
  host: 127.0.0.0

希望它对你有用:)
