我刚刚在我的Mac OS Lion机器上安装了postgresql。我已经卸载并重新安装了
pg
gems

当我运行
psql
时,我得到以下错误:

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"?

结果:

如何解决此错误?谢谢

首先要尝试的是:

psql-h本地主机


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。通过tcp/ip连接可以避免这种情况。

PostgreSQL server是否在同一台计算机上运行?你能检查一下它在哪里监听连接吗(可能是通过
lsof
)?你是如何安装postgresql的?你提到了gems,但它们是专门针对ruby库的。我更新了我的帖子来回答你的问题。谢谢你。。。我也有这个错误。我尝试使用psql添加“-h localhost”,效果很好。但当只有psql[database]时,它不会。如何修复此问题?搜索.s.PGSQL.5432,然后改为-h/path/to/that/directory(或将PGHOST设置为该路径)。
