这里是我的问题。我想创建一个博客。我运行“轨道的新博客”。 Everythign是OK,直到我尝试“耙分贝:创建”。它返回一个错误:
rake aborted!
Please install the postgresql adapter: `gem install activerecord-postgresql-adap
ter` (pg is not part of the bundle. Add it to Gemfile.)
当我尝试安装PG适配器我得到这样的:
Temporarily enhancing PATH to include DevKit...

ERROR: Error installing activerecord-postgresql-adapter:

需要配置选项。
我的Gemfile:
source 'https://rubygems.org'
gem 'rails', '3.2.12'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem "pg"
# 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'
有什么想法?
你有安装Postgres的?如果是这样,请确保pg_config.exe是在PATH中。或者请使用--with-pg-config
或–with-pg-dir
键:
gem install pg --with-pg-config=<path>
见https://github.com/ged/ruby-pg/blob/master/README-Windows.rdoc细节
卸载pg
宝石,和Windows安装postgres-pr
从的Gemfile删除:
gem "pg"
并提出:
gem "postgres-pr"
然后运行:
bundle install
或gem install postgres-pr
或不过你要安装的宝石
