के बाद मैं काढ़ा अद्यतन और काढ़ा उन्नयन किया, मेरे पोस्टगर्ल्स कुछ समस्या हो गई। मैंने पोस्टग्रेज की स्थापना रद्द करने और फिर से स्थापित करने की कोशिश की, लेकिन यह भी काम नहीं किया।
यह त्रुटि संदेश है (मुझे भी यह त्रुटि संदेश मिला है जब मैं रेक डीबी करने की कोशिश करता हूं: माइग्रेट करता हूं)
$ 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"?मैं इसे कैसे सुलझाऊं?

होमब्रे संस्करण: 0.9.3

और यही मैंने किया।

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".

If you want to create a new database system, either remove or empty
the directory "/usr/local/var/postgres" or run initdb

Is the server running locally and accepting

लेकिन मैं rake db:migrateअपने रेल ऐप में चलता हूं, यह दिखाता है:

Couldn't create database for {"adapter"=>"postgresql", "encoding"=>"unicode", "database"=>"riy_development", "pool"=>5, "username"=>nil, "password"=>nil}अंत में मुझे इसका हल मिल गया।
$ sudo mkdir /var/pgsql_socket/
$ sudo ln -s /private/tmp/.s.PGSQL.5432 /var/pgsql_socket/यह समाधान थोड़ा मुश्किल है, लेकिन यह काम करता है। आशा है कि किसी के पास बेहतर समाधान होगा
अपडेट करें
यह मेरे लिए भी काम करता है।
rm /usr/local/var/postgres/postmaster.pid

मुझे आपकी वही समस्या हो रही है, लेकिन आपका समाधान मेरे काम नहीं आया। मुझे लगता है कि यह एक अनुमति समस्या है, लेकिन मुझे इसे ठीक करने के लिए फ़ाइल अनुमतियों का ज्ञान नहीं है।

उन लोगों के लिए जो होमब्रे के माध्यम से पीजी स्थापित करते हैं और समस्या हो रही है, मुझे एक और जवाब मिला। बस pg रत्न को अनइंस्टॉल करें और Homebrew config के साथ पुनर्स्थापित करें। इसका जवाब stackoverflow.com/a/19609228/1072058 पर देखें ।
