Images are often hard to read, don’t necessarily contain all of the relevant information and are not mobile friendly.

• Now what exactly are the details of installation/configuration? From the C:\Users\ path I suspect that you are using some version of MS Windows (hopefully 10) - if so, prefix the topic like this “Windows 10: Ecto.Adapters.Postgres was not compiled” as to attract the attention of forum members who actually develop on Windows.
  (Aside: In the days of Windows 7 I came to the conclusion that Windows got in the way more often than not for non-Microsoft centric web development - so I switched platforms)

• What was the installation process you’ve followed (if you used a package manager - which one)?

  • Which version of Erlang is installed? (your Elixir was complied with 19 - but what is actually installed)
  • Which version of Elixir is installed?
  • Which version of Phoenix do you have installed?
  • What version of Ecto are you trying to use?

When things go wrong, things tend to get complicated fast.
