When you try run mix --version in terminal (example fish shell). But it made this error: fish: Job 1, 'mix --version' terminated by signal SIGSEGV This is the way to fix it: # Erlang set -xg KERL_CONFIGURE_OPTIONS "--disable-jit" asdf install erlang 25.2.3 asdf global erlang 25.2.3 # Elixir asdf install elixir 1.14.5 asdf global elixir 1.14.5
