Hi,
I’m trying to start an observer for my elixir app, but I’ve received an error:
Interactive Elixir (1.13.3) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)> :observer.start
20:24:40.917 [error] WX ERROR: Could not load library: :load_failed
Failed to load NIF library: 'dlopen(/Users/yoonwaiyan/.asdf/installs/erlang/24.0.4/lib/wx-2.0.1/priv/wxe_driver.so, 2): Symbol not found: __ZN10wxListbook12SetImageListEP11wxImageList
Referenced from: /Users/yoonwaiyan/.asdf/installs/erlang/24.0.4/lib/wx-2.0.1/priv/wxe_driver.so
Expected in: flat namespace
in /Users/yoonwaiyan/.asdf/installs/erlang/24.0.4/lib/wx-2.0.1/priv/wxe_driver.so'
I’m using macOS Big Sur with elixir/OTP installed with asdf. Appreciate any help 
Where Next?

This is just a guess on my part, but make sure you have installed all of the required dependencies before you do
asdf install erlang <version>.Have a look at the OSX section of the Erlang plugin README. It may provide you some help:

The reason is that Erlang was installed before installing wxwidgets. It works now after some complication in having erlang to compile properly after installing wxwidgets.
