可能还有其他问题正在发生...但这可能是您的问题之一：
Please install the postgresql adapter: gem install activerecord-postgresql-a dapter (pg is not part of the bundle. Add it to Gemfile.) (LoadError) -
但我的项目中没有使用 Postgre。我使用 MySQL。
-
您使用远程 MySQL 数据库吗？也许这可以帮助：stackoverflow.com/questions/5397028/…
-
你能从 Gemfile 发布你的制作组吗？
-
我的 Gemfile: source 'rubygems.org' gem 'rails', '3.2.1' gem 'mysql2' group :assets do gem 'sass-rails', '~> 3.2.3' gem 'coffee-rails', '~> 3.2.1' gem 'uglifier', '>= 1.0.3' end gem 'jquery-rails' gem 'devise' gem 'calendar_date_select' gem 'watu_table_builder', :require => " table_builder" gem 'ice_cube' gem 'activerecord-postgresql-adapter'
