私は、ビルドサーバが(localhost:5432)のようですので、それはだと思うし、私はそれが、この解決策は何ですかポート4000 See this answer for my coming to that conclusion.

にusallyであるフェニックスとよく果たしているとは思いませんか？

私は、この設定を持っているdev.exを変更：

config :phoenix_chat, PhoenixChat.Endpoint, 
    http: [port: {:system, "PORT"}], 

その後、私はPORT=4000 mix testにタスクを設定するが、私はまだ同じエラーを取得します。

EDIT：それは私がポートを設定することが表示されないエラーがまだあるので、働いていた：

PORT=4000 mix test 
09:18:34.884 [error] GenServer #PID<0.183.0> terminating 
** (DBConnection.ConnectionError) tcp connect (localhost:5432): connection refused - :econnrefused

だから私は今、解決策がthisかもしれないと思います。私はsshキーを追加することについてたくさん知りません。

Answer 1

私のラップトップがクラッシュし、postmaster.pidファイルが/usr/local/var/postgresにあります。

これを削除した後、私のpostgresはうまくいきました。

postgresが正常に実行されているかどうかを確認する場合は、pq_readyを実行して出力を取得できます。あなたは：/tmp:5432 - accepting connectionsを取得する必要があります - あなたのポートはあなたの設定によって異なるかもしれません。

楽しくお楽しみください！
