Codename-404
Hi, I am new to elixir, tried several ways to install elixir on my Mac M1.
Everything works on terminal or if I just create a test.exs file.
But when I want to add Phoenix or even with a “mix new my_project”, it always gives me this error below,
Compiling 1 file (.ex)
== Compilation error in file lib/learning.ex ==
** (ArgumentError) could not call Module.put_attribute/3 because the module Learning.MixProject is already compiled
(elixir 1.15.7) lib/module.ex:2310: Module.assert_not_readonly!/2
(elixir 1.15.7) lib/module.ex:2007: Module.__put_attribute__/5
lib/learning.ex:2: (module)
I tried with homebrew, with asdf. Can anyone assist me solving this issue?
Looking forward to get started with elixir ~

Are you using the ARM native (M1) homebrew, oe emulated one through Rosetta 2?

Change that. Use native ARM homebrew.

The exact code came with “mix new learning”

That solved the issue. Thank you ~
All I had to do it, get out of inner session CTRL + D,
reinstall homebrew for amr64,
install elixir.
Thank you ~

It’s a common gotcha. Glad you solved it.
