我跟着這篇文章來安裝的Postgres https://gorails.com/setup/ubuntu/15.04的Ubuntu 15.04安裝PostgreSQL
但我米就試圖啓動PostgreSQL的
[email protected]:~$ sudo -u postgres createuser vihaan -s
createuser: could not connect to database postgres: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
這裏得到這個錯誤是由Postgres的包安裝的消息。

它看起來像DB發動機不運轉。你有沒有嘗試過：「sudo service postgresql9.3 start」或類似的東西。 –
