@ShaneSegal as a work-around, do one of the following

• Manually set the Internal Erlang SDK:

  1. File > Project Structure
  2. Click SDK
  3. Click +
  4. Select either "Erlang SDK" (if you have intellij-erlang plugin installed) or "Erlang for Elixir SDK" (if you only have IntelliJ Elixir plugin installed)
  5. Pick the SDK directory Erlang. It is /usr/local/Cellar/erlang/VERSION/lib/erlang
  6. Click OK

  Now use that Erlang SDK in the Elixir SDK.

  1. File > Project Structure
  2. Click SDK
  3. Select your Elixir SDK
  4. Ensure the Internal Erlang SDK dropdown has your Erlang SDK selected. If it worked correctly Class Paths tab will list ebin directories for both Elixir and Erlang like in the pictures in the SDK section of the README.
• Run mix test Run Configuration and it will migrate your Elixir SDK and fill in the Internal Erlang SDK.

That looks to have worked, thanks!
