So is there any other way around? You’ve mentioned erlang installer but I don’t know the follow up steps and I want to install elixir later. But the main thing here I have to switch between older and newer otp version. That’s why I thought asdf will be good here in that case. Can you suggest if that I can do the same thing here?

Yes, the Erlang Solutions installer handles this nicely. You get a GUI to choose your releases:
The OTP versions are installed in your home: ~/.erlangInstaller/
find ~/.erlangInstaller -maxdepth 1
/Users/feld/.erlangInstaller
/Users/feld/.erlangInstaller/available-releases.json
/Users/feld/.erlangInstaller/default
/Users/feld/.erlangInstaller/22.3.4.1
the default is a symlink to the current version you want to be your default OTP version. Then you just update your $PATH to include ~/.erlangInstaller/default/bin and it’s ready to go.
On a Mac you can’t just update your PATH in your shell anymore, so make sure you add it to /etc/paths.d/$username file or some programs/utilities will not inherit the PATH.
edit: here’s the contents of my /etc/paths.d/feld file:
/Users/feld/bin
/Users/feld/.erlangInstaller/default/bin
/Users/feld/elixir-1.10.2/bin
/opt/local/bin/
/Users/feld/node_modules/.bin

You can, but it won’t be picked up globally in MacOS. It might be fine for you, but if you run into problems you need to edit /etc/paths.d/$username and add it there too.
MacOS does not behave like a typical Linux/Unix anymore when it comes to environment variables.

Usually if I’m launching iterm2 for erlang so technially I should update the path there right? I didn’t understand properly where I can add this
~/.erlangInstaller
▶ ls
22.3.4.1 available-releases.json default
~/.erlangInstaller
▶ cd default
~/.erlangInstaller/default
▶ ls
Install bin erts-10.7.2.1 lib misc releases usr
~/.erlangInstaller/default
▶ cd bin
.erlangInstaller/default/bin
▶ ls
ct_run epmd erlc no_dot_erlang.boot start start.script start_erl to_erl
dialyzer erl escript run_erl start.boot start_clean.boot start_sasl.boot typer
.erlangInstaller/default/bin
I installed it and I can see it here.

Learning new stuff here now. Thanks

stow is old. most newer ways, including nvm, rvm do this:
- install software in unconventional location
- mung environment variable to point here
Stow does it differently:
- install software in unconventional location
- symlink all stuff into /usr/local, so you don’t need to mung environment variables
It is a matter of choice. I like the stow way, however please keep in mind that it does not work in certain environments, like if you don’t have root permission or on Windows.

I think it is only necessary in the case you need JInterface, a method to simulate a java application as an erlang node
