I get an error when using mix ecto.create for my first Elixir project

Question

When I do mix ecto.create I get following error:

could not compile dependency :mint, "mix compile" failed. Errors may have been logged above. You can recompile this dependency with "mix deps.compile mint --force", update it with "mix deps.update mint" or clean it with "mix deps.clean mint"

The mentioned logs are: ==> mint

I tried reinstalling everything! Maybe there is something wrong with postgresql?

Answer 1

When you create a new Phoenix project with mix phx.new test you just need to run the commands that are displayed in your terminal from that directory. You should see and follow this in your terminal:

We are almost there! The following steps are missing: Fetch and install dependencies? [Yn]

(I usually directly enter 'Y' here instead of mix deps.get the first time)

$ cd test
$ mix deps.get

Then configure your database in config/dev.exs and run:

$ mix ecto.create

Start your Phoenix app with:

$ mix phx.server

You can also run your app inside IEx (Interactive Elixir) as:

$ iex -S mix phx.server

If it doesn't work, reinstall Phoenix.

I hope it helps!
