【问题描述】：

我正在使用带有数据库的 Rails 4 作为 postgres9.4。而使用 hstore 类型列作为动态字段。我收到错误

PG::UndefinedFile: 错误: 无法打开扩展控制文件 “/usr/pgsql-9.4/share/extension/hstore.control”：没有这样的文件或目录：如果不存在则创建扩展 “hstore”/var/www/Q3/mailchimp/campaign_app/vendor/bundle/ruby/2.2.0/gems/activerecord-4.2.1/lib/active_record/connection_adapters/postgresql_adapter.rb:592:in async_exec' /var/www/Q3/mailchimp/campaign_app/vendor/bundle/ruby/2.2.0/gems/activerecord-4.2.1/lib/active_record/connection_adapters/postgresql_adapter.rb:592:inblock in exec_no_cache' /var/www/Q3/mailchimp/campaign_app/vendor/bundle/ruby/2.2.0/gems/activerecord-4.2.1/lib/active_record/connection_adapters/abstract_adapter.rb:473:in block in log' /var/www/Q3/mailchimp/campaign_app/vendor/bundle/ruby/2.2.0/gems/activesupport-4.2.1/lib/active_support/notifications/instrumenter.rb:20:ininstrument' /var/www/Q3/mailchimp/campaign_app/vendor/bundle/ruby/2.2.0/gems/activerecord-4.2.1/lib/active_record/connection_adapter/abstract_adapter.rb:467:in log' /var/www/Q3/mailchimp/campaign_app/vendor/bundle/ruby/2.2.0/gems/activerecord-4.2.1/lib/active_record/connection_adapters/postgresql_adapter.rb:592:inexec_no_cache' /var/www/Q3/mailchimp/campaign_app/vendor/bundle/ruby/2.2.0/gems/activerecord-4.2.1/lib/active_record/connection_adapters/postgresql_adapter.rb:584:in execute_and_clear' /var/www/Q3/mailchimp/campaign_app/vendor/bundle/ruby/2.2.0/gems/activerecord-4.2.1/lib/active_record/connection_adapters/postgresql/database_statements.rb:160:inexec_query' /var/www/Q3/mailchimp/campaign_app/vendor/bundle/ruby/2.2.0/gems/activerecord-4.2.1/lib/active_record/connection_adapters/postgresql_adapter.rb:342:in enable_extension' /var/www/Q3/mailchimp/campaign_app/vendor/bundle/ruby/2.2.0/gems/activerecord-4.2.1/lib/active_record/migration.rb:662:inblock in method_missing'

我试试

sudo yum install postgresql postgresql-contrib
sudo yum install postgresql-server.x86_64 postgresql94-contrib.x86_64

但不要为我工作

【解决方案1】：

在 Centos 中，我错误地安装了 postgres8.3 软件包，但我使用的是 postges9.4。删除 postgres8.3 包后，它工作正常
