如何在自制软件中安装特定版本的公式？例如,postgresql-8.4.4而不是最新的9.0.

在我做了brew更新和brew升级之后,我的postgres遇到了一些问题.我试图卸载postgres并重新安装,但它也没有用.

这是错误消息.(当我尝试执行rake db:migrate时,我也收到此错误消息)

$ psql
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"?

我该如何解决？

Mac版:山狮.

自制版:0.9.3

postgres版本:psql(PostgreSQL)9.2.1

这就是我所做的.

12:30 ~/D/works$ brew uninstall postgresql

12:31 ~/D/works$ brew uninstall postgresql

我安装了PostgreSQL 8.4,Postgres客户端和Pgadmin 3.对于控制台客户端和Pgadmin用户"postgres"的身份验证失败.我输入的用户为"postgres",密码为"postgres",因为之前有效.但现在身份验证失败了.我之前做过几次没有这个问题.我该怎么办？会发生什么？

psql -U postgres -h localhost -W
Password for user postgres: 
psql: FATAL:  password authentication failed for user "postgres"
FATAL:  password authentication failed for user "postgres"

这个问题可能看起来像是一个副本:如何在我的Mac上卸载postgresql(运行Snow Leopard)但是,有两个主要的区别.我正在运行Lion,我正在尝试卸载PostgreSQL 9.0.4.我查看了最后一个问题及其引用的链接,但是当我运行此命令时,我没有找到名为"uninstall-postgresql"的文件:

sudo find / -name "*uninstall-*"  

所以,我认为这意味着9.0.4的卸载过程与8.x的卸载过程不同.

我在不同的地方看到了几个描述手动卸载方法的帖子,但同样地,我的机器上没有引用的一些目录/文件.

我们将非常感谢您提供的任何帮助或指导.

仅供参考,这是用于从雪豹中卸载postgres的另一张海报的链接.当我试图逐步执行这些命令时,大多数命令都被"未找到命令"的变体所阻塞.

更新:

除此之外brew uninstall postgres,我应该手动删除以下任何文件/目录吗？请记住,我想完全擦除平板,没有数据文件/数据库表或任何东西.

我使用自制软件在我的Mac(10.10.1/Yosemite)上安装了Postgresql 9.4.0.这是行不通的.

我在〜/ Library/LaunchAgents中创建了/usr/local/opt/postgresql/homebrew.mxcl.postgresql.plist的软链接.

如果我尝试手动加载postgres,我会收到"正在进行操作"的消息

> launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
/usr/local/Cellar/postgresql/9.4.0/homebrew.mxcl.postgresql.plist: Operation already in progress

然而,postgres似乎没有运行.

> ps auxw | grep post
billmcn           670   0.0  0.0  2424272    452 s000  R+   10:12PM   0:00.01 grep post

我无法连接命令行客户端.

> psql
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"?

据我所知,我已经尝试了其他 Stackoverflow线程上建议的所有修复程序来讨论这个问题.特别:

• 我已经卸载并重新安装了postgres和随附的Ruby gem.我的机器上没有postgres 8.0版本.
• 我已经验证了psql客户端程序是Homebrew安装的9.4.0版本而不是Mac系统二进制文件.
• 我已经验证/usr/local/var/postgres/postmaster.pid不存在.
• 我重新启动了机器.

我之前确实有Homebrew postgres在这台机器上工作.我认为破坏它的是从版本8升级到版本9,但我不确定.

我没有任何需要保留的数据库.我愿意用postgres开始清洁; 我现在只需要让它上班.有任何想法吗？

该问题似乎是/ usr/local/var/postgres目录的权限.这是我的var目录在事情不起作用时的样子.

ll /usr/local/var/
drwxr-xr-x  3 …

最近升级到OSX Mavericks已经破坏了我的Rails应用程序的数据库连接.

当我尝试从数据库中提取时,服务器返回以下错误:

PG::ConnectionBad (could not connect to server: Connection refused
    Is the server running on host "localhost" (::1) and accepting
    TCP/IP connections on port 5432?
could not connect to server: Connection refused
    Is the server running on host "localhost" (127.0.0.1) and accepting

could not connect to server: Connection refused
    Is the server running on host "localhost" (fe80::1) and accepting
    TCP/IP connections on port 5432?

当psql我试着跑步时,我得到:

psql: could not connect to server: No …

我不知道如何解决这个问题

我不知道为什么我在尝试时遇到此错误runserver:

我目前正在尝试在我的iMac上运行postgresql(9.3)但是我遇到了一些用户postgres和psql连接的问题.

我买了一台迁移到Lion的iMac老一代(雪豹).正如其他StackOverflow主题所示,我在.bash_profile上添加了这一行:

export PATH=/Library/PostgreSQL/9.3/bin:/usr/bin:$PATH

启动pg时:

sudo su postgres -c '/Library/PostgreSQL/9.3/bin/pg_ctl -D /Library/PostgreSQL/9.3/data/ -m fast start'

它返回:

su: unknown login: postgres

我该怎么办 ？

无法解决是什么错误。

django.db.utils.OperationalError: server closed the connection unexpectedly
    This probably means the server terminated abnormally
    before or while processing the request.

当我运行以下任何命令时，我一直在获取跟踪

1. python manage.py makemigrations
2. python manage.py runserver
