Installing Phoenix 1.7.7 with Erlang 26 gives segmentation fault on Mac M1

after upgrading Elixir and Erlang 26 with homebrew, installing Phoenix causes a segmentation fault:

$ mix archive.install hex phx_new
Resolving Hex dependencies...

New:
  phx_new 1.7.7
* Getting phx_new (Hex package)

Segmentation fault: 11

How can this be fixed?

Solution

  • after some digging, I found that homebrew was configured for x86 architecture with Rosetta active, instead arm64.

    To check your CPU architecture, run uname -m

    $ uname -m 
arm64

    Check your homebrew configuration:

    $ brew config
...
macOS: 13.4.1-x86_64
CLT: N/A
Xcode: 14.3
Rosetta 2: true

    to switch it to arm64, run:

    eval "$(/opt/homebrew/bin/brew shellenv)"

    then verify that the architecture is configured correctly:

    $ brew config
...
macOS: 13.4.1-arm64
CLT: N/A
Xcode: 14.3
Rosetta 2: false

    Then reinstall Elixir and Erlang

    brew reinstall elixir erlang

    and install Phoenix via mix archive.install hex phx_new
