:observer.start() broken after updating wxWidgets

WestKeys

:observer’s color scheme was off for Dark Mode on Big Sur, so I googled and followed the steps here to fix it.

Afterwards when running iex I started getting:

>iex /usr/local/Cellar/elixir/1.11.3/bin/elixir: line 230: exec: erl: not found

I then ran brew reinstall elixir

Running iex now worked, however :observer.start() didn’t.

Any ideas?

Discovered asdf while troubleshooting. Reinstalled erlang, elixir using asdf and it seems to be working now.

I have the same issue with Erlang/23.3.2, Elixir 1.11.4 on macOS BigSur 11.2.3, since wxWidgets fixed this macOS issue within 3.1.* but the available version from https://formulae.brew.sh/formula/wxmac is 3.0.5.1 , we have to manually modify local wxmac.rb file to use with the current latest version 3.1.5 of wxWidgets, here are my steps to resolve this issue, hope it can be useful for your reference.

1, run brew edit wxmac after changed as below:

2, run brew upgrade wxmac --build-from-source to upgrade

3, you may need to reinstall Erlang/Elixir via brew.

4, Make sure the completed Xcode tool installed.

After the above operations, I can run :observer.start() in mix shell now.

FYI, upgrade to erlang/otp 24.

After remove wxmac and reinstall it via:

brew install wxmac --build-from-source,

it will also reinstall erlang@24 as a dependance, here are outputs:

It works for me to upgrade to erlang@24 by use brew.

FYI,

About 2 days ago, brew formula wxmac renamed as wxwidgets and upgrade to use wxWidgets-3.1.5, if you had manually edited the wxmac.rb refer the above mentioned in your local path /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula, please remember to revert the changes in that folder, and then use brew to update and upgrade erlang will keep the :observer works well.
