我刚在Mac OS Lion机器上安装了postgresql。我已经卸载并重新安装了pg宝石。
当我运行psql时，我收到以下错误：
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
正在运行which psql：
/usr/local/bin/psql
我使用自制软件安装了postgresql
以下是postgres的lsof结果：

如何解决此错误？谢谢！
答案 0 :(得分：2)
首先要尝试：
psql -h localhost
可能是客户端和服务器正在尝试为UNIX域套接字使用不同的文件位置。您可以通过连接tcp / ip来避免这种情况。
