আমি ব্রিউ আপডেট এবং ব্রিউ আপগ্রেড করার পরে, আমার পোস্টগ্রাগুলি কিছু সমস্যা পেয়েছে। আমি পোস্টগ্রাগগুলি আনইনস্টল করে আবার ইনস্টল করার চেষ্টা করেছি, তবে এটি কার্যকর হয়নি।
এটি ত্রুটি বার্তা ((আমি যখন রেক ডিবি করার চেষ্টা করি তখনও আমি এই ত্রুটি বার্তাটি পেয়েছি: স্থানান্তরিত)
$ 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"?
আমি কিভাবে এটা সমাধান করতে পারে?
ম্যাক সংস্করণ: মাউন্টেন সিংহ।
হোমব্রু সংস্করণ: 0.9.3
পোস্টগ্র্যাস সংস্করণ: পিএসকিএল (পোস্টগ্রিএসকিউএল) 9.2.1
এবং এই আমি কি করেছি।

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".

এখন, আমি হোবারব্রু পুনরায় ইনস্টল করার পরে, যখন আমি ব্যবহার করি $ psql
, এটি কোনও ত্রুটি বার্তা প্রদর্শন করে না।
তবে আমি rake db:migrate

পরিশেষে আমি সমাধানটি সন্ধান করি।
$ sudo mkdir /var/pgsql_socket/
$ sudo ln -s /private/tmp/.s.PGSQL.5432 /var/pgsql_socket/
এই সমাধানটি সামান্য কৌশলযুক্ত, তবে এটি কার্যকর হয়। আশা করি কারওরই এর থেকে ভাল সমাধান হবে
হালনাগাদ
এটি আমার পক্ষেও কাজ করে।
