업데이트 및 양조 업그레이드를 수행 한 후 postgres에 문제가 발생했습니다. postgres를 제거하고 다시 설치하려고했지만 작동하지 않았습니다.
이것은 오류 메시지입니다. (rake db : migrate를 수행하려고 할 때도이 오류 메시지가 나타납니다)
$ 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"?
어떻게 해결할 수 있습니까?
맥 버전 : 산 사자.
사제 버전 : 0.9.3
postgres 버전 : psql (PostgreSQL) 9.2.1
그리고 이것이 내가 한 일입니다.

The files belonging to this database system will be owned by user "laigary".
This user must also own the server process.
The database cluster will be initialized with locale "en_US.UTF-8".
The default text search configuration will be set to "english".
initdb: directory "/usr/local/var/postgres" exists but is not empty
If you want to create a new database system, either remove or empty
the directory "/usr/local/var/postgres" or run initdb
with an argument other than "/usr/local/var/postgres".

이제 howbrew를 다시 설치 한 후을 사용할 때 $ psql
오류 메시지가 표시되지 않습니다.
그러나 rake db:migrate
레일 앱에서 실행 하면 다음과 같이 표시됩니다.

마지막으로 해결책을 찾습니다.
$ sudo mkdir /var/pgsql_socket/
$ sudo ln -s /private/tmp/.s.PGSQL.5432 /var/pgsql_socket/
이 솔루션은 조금 까다 롭지 만 작동합니다. 누구나 더 나은 솔루션을 갖기를 바랍니다.
