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"? 无法连接到服务器:没有这样的文件或目录服务器是否在本地运行并接受Unix域套接字“/tmp/.s.PGSQL.5432”上的连接?

okay, This is what you should do: 好的,这是你应该做的:
/var/pgsql_socket
(as per the plist image) where as rails is trying to find the socket file in /tmp
. unix套接字应该在/var/pgsql_socket
(根据plist图像),其中rails试图在/tmp
找到套接字文件。 I believe this is the reason for error. 我相信这是错误的原因。 so Edit your database.yml
& explicitly add socket location. 所以编辑你的database.yml
并显式添加套接字位置。 so your final database.yml should look like this . 所以你的最终database.yml应该是这样的 。 change the file location for your unix socket location. 更改unix套接字位置的文件位置。 try to connection now? 现在尝试连接? 2) If it still doesn't connect. 2)如果仍然没有连接。 verify that postgres server is actually running 验证postgres服务器实际上是否正在运行
$ netstat -a | grep postgre
if its running, try connecting to it from terminal using psql
command. 如果它正在运行,请尝试使用psql
命令从终端连接到它。 incase its, not running. 加入它,而不是运行。 try starting it manually 尝试手动启动它
pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start
If it still doesn't start, Are there any error messages in the server.log? 如果它仍然无法启动,server.log中是否有任何错误消息? If yes do post them here. 如果是,请在此处发布。
Good luck! 祝好运! =======UPDATED=============== =======已更新===============
