Are you using Elixir on Windows and Powershell?

There is another way by replacing iex directly.

IEX in Windows Powershell?

@joaoevangelista You can remove the iex command by adding this command to your Powershell profile: remove-item alias:iex -Force Make sure to restart Powershell after adding it, so that your profile is reloaded. And if you will use any command from the web they might now fail if they are relying on iex.
