我正在尝试按照本教程进行操作，无法完成pg的设置。 https://shellycloud.com/blog/2013/10/adding-search-and-autocomplete-to-a-rails-app-with-elasticsearch
我使用postgres应用程序在我的计算机上设置了pg，并且我使用bundle install在我的应用程序中成功安装了它，但每当我运行rake db：seed时，我都会收到以下错误。 pg正在端口5432上运行，我尝试再次卸载和安装。 rails服务器运行正常，psql正在终端中运行。
我一直在寻找几个小时，找不到任何可以解释问题的东西 - 大多数答案都与我没有使用的太阳黑子solr有关。我已按照postgres应用程序文档中的建议增加了系统的共享内存：
sudo sysctl -w kern.sysv.shmall=65536
sudo sysctl -w kern.sysv.shmmax=16777216
我将以下内容添加到我的开发配置中，因为另一个答案提到了这是一个潜在的解决方案：
config.action_mailer.perform_deliveries = false
非常感谢任何帮助！
这是我运行rake db：seed
时遇到的错误michaels-air:bookstore_search michaeltaylor$ rake db:seed --trace
** Invoke db:seed (first_time)
** Execute db:seed
** Invoke db:abort_if_pending_migrations (first_time)
** Invoke environment (first_time)
