Elixir mix auto acknowledge

Question

I want to run tests of my Phoenix app on Travis-CI.

Log excerpt:

$ MIX_ENV=test mix do deps.get, compile, test

Could not find hex, which is needed to bu         


        

Answer 1

You can add this command to your before_install section in .travis.yml

• mix local.hex --force

After of course, you've already installed elixir in a previous command. I cargo culted this .travis.yml from an existing elixir project on github.

language: erlang
env:
  - ELIXIR="v1.0.0"
otp_release:
  - 17.1
before_install:
  - mkdir -p vendor/elixir
  - wget -q https://github.com/elixir-lang/elixir/releases/download/$ELIXIR/Precompiled.zip && unzip -qq Precompiled.zip -d vendor/elixir
  - export PATH="$PATH:$PWD/vendor/elixir/bin"
  - mix local.hex --force
script: "MIX_ENV=test mix do deps.get, test"

Answer 2

As with any unix command, you could pipe yes into the mix command:

yes | MIX_ENV=test mix do deps.get, compile, test
