我正在使用 Mac OS X 10.8.5,并尝试使用 Homebrew 安装 PostgreSQL。当我运行 brew info postgresql 时,出现了一些错误和警告,我已经修复了其中的几个。然而,我不知道如何解决其余的问题。
$brew info postgresql

==> Caveats
If builds of PostgreSQL 9 are failing and you have version 8.x installed,
you may need to remove the previous version first. See:
https://github.com/Homebrew/homebrew/issues/issue/2510
To migrate existing data from a previous major version (pre-9.3) of PostgreSQL, see:
http://www.postgresql.org/docs/9.3/static/upgrading.html
When installing the postgres gem, including ARCHFLAGS is recommended:
ARCHFLAGS="-arch x86_64" gem install pg
To install gems without sudo, see the Homebrew wiki.
To have launchd start postgresql at login:
ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents
Then to load postgresql now:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
Or, if you don't want/need launchctl, you can just run:
postgres -D /usr/local/var/postgres
当我运行服务器时,会出现以下信息:
/usr/local/rvm/gems/ruby-2.0.0-p353/gems/activerecord-4.0.0/lib/active_record/connection_adapters/postgresql_adapter.rb:825:in `initialize': could not connect to server: No such file or directory (PG::ConnectionBad)
Is the server running locally and accepting
connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"?
我已经卸载了postgresql并重新安装,但似乎我无法删除postgresql 8.x版本。
我阅读了几篇不同的文章来正确安装和运行postgreSQL,并尝试了他们建议的方法,但对我来说似乎都没有起作用。
ps -ef | grep postgres
