Hello, welcome to the forum…

As mentionned, You need to be in the root folder of an Elixir application to do this.

The minimum viable reproduction is…

$ mix new koko
* creating README.md
* creating .formatter.exs
* creating .gitignore
* creating mix.exs
* creating config
* creating config/config.exs
* creating lib
* creating lib/koko.ex
* creating test
* creating test/test_helper.exs
* creating test/koko_test.exs

Your Mix project was created successfully.
You can use "mix" to compile it, test it, and more:

    cd koko
    mix test

Run "mix help" for more commands.
$ cd koko/
$ iex -S mix
Erlang/OTP 21 [erts-10.2.3] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [hipe]

Compiling 1 file (.ex)
Generated koko app
Interactive Elixir (1.8.1) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)>

To check if You have the file…

$ ls -l mix*
-rw-r--r--  1 xxx  staff  565 15 jul 16:29 mix.exs
