Install error (poorly) about elixir-china HOT 4 CLOSED

I guess it's because Postgres. Could you check the config to ensure you can connect to Postgres directly with the same config?

It's because of Postgres, I have such error

[error] Postgrex.Protocol (#PID<0.194.0>) failed to connect: ** (DBConnection.ConnectionError) tcp connect (localhost:5432): connection refused - :econnrefused

I have postgres installed by brew install postg***

I start postgres by brew services start postgresql

Is the default username & password the same as in the config file "postgres"?

@zzz6519003 I don't know wha't your username & password, but they have to be same with the real ones of PostgreSQL.
