The new release of Igniter might fail, since this issue was just happened to me:
(I’d like to upload an image, but I’m a new user)

asdf@897471af8b62:/tmp$ mix igniter.new toy_bank --install ash --extend ets
* creating README.md
* creating .formatter.exs
* creating .gitignore
* creating mix.exs
* creating lib
* creating lib/toy_bank.ex
* creating test
* creating test/test_helper.exs
* creating test/toy_bank_test.exs

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

    cd toy_bank
    mix test

Run "mix help" for more commands.

Actually, I tried many erlang/elixir versions, and all fail.

Is there a way to use previous version of Igniter? I did not find a way to do so in this forum.

Please help.
