问题描述

我正在尝试为Mac（10.7 Lion）上的Rails应用程序在本地安装Postgres安装程序。

I am trying to get postgres setup locally for a rails app on my mac (10.7 Lion).

我安装了并启动它，现在我在状态栏中有一个大象告诉我postgres正在运行。

I installed postgresapp and launched it, I now have an elephant in my status bar telling me that postgres is running.

我可以了解它创建者：

psql -h localhost

但是当我简单地运行 psql 时，会出现此错误：

But when I simply run psql I get this error:

我说的是：

PATH="/Applications/Postgres.app/Contents/MacOS/bin:$PATH"

在〜/ .bashrc 并打开一个新终端。但是没有骰子。

In ~/.bashrc and opened a new terminal. But no dice.

当我运行哪个psql 时，我得到 / usr / bin / psql

不太确定该怎么做。.我对于UNIX系统还是很陌生。我应该将 / usr / bin / psql 链接到 /Applications/Postgres.app/Contents/MacOS/bin/psql ？

Not really sure what to do.. I am still pretty new to unix systems. Should I symlink /usr/bin/psql to /Applications/Postgres.app/Contents/MacOS/bin/psql?

推荐答案

在运行Mountain Lion的新MacBook Pro上，我遇到了类似的问题。我下载了，当我启动导轨时，出现以下错误：

I had a similar issue on my new MacBook Pro running Mountain Lion. I downloaded the PostgresApp and when I fired up rails I received the following error:

`initialize': could not connect to server: No such file or directory (PG::Error)
Is the server running locally and accepting
connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"?

要解决此问题，我必须在数据库中明确定义主机和端口.yml 文件，如下所示：

To fix this I had to explicitly define the host and port in my database.yml file like so:

development:
  adapter: postgresql
  encoding: unicode
  database: my_app_development
  pool: 5
  username: tony
  password: stark
  host: localhost
  port: 5432
