Hi everybody.
I’m quite new to Elixir, I’m in my first steps.

I successfully build an app in a Mac computer using Phoenix.
When I git clone, mix deps.get, everything seems fine.

When I run mix ecto.create, it shows:

21:20:32.077 [error] GenServer #PID<0.211.0> terminating

I have postgresql installed and everything seems fine with the installation.

Could anyone help me, please?

Try updating Postgrex with mix deps.update postgrex.

While you’re at it, run mix hex.outdated to find outdated packages and update those.

To be specific, the version of postgrex that you’re using does not support Postgres 10

Your explanation was also important. I’m still learning about Phoenix. Thank you so much sir
