My adventures on this amazing distributed computing platform.
Installing Erlang through asdf is probably the easiest way to get it up and running on macOS. You'll need OpenSSL to run the installation, and the easiest way to get it is through Homebrew:
brew install openssl
Homebrew's OpenSSL formula is keg-only, and it means that even after installed it won't be globally available in your system. There's an useful note about it on asdf-erlang's README.md, but I ended up with a command that would use
brew to get the path of the OpenSSL installation:
# first, export this Kerl-specific variable with the following content export KERL_CONFIGURE_OPTIONS="--without-javac --with-ssl=$(brew --prefix firstname.lastname@example.org)" # then, install the Erlang version you want (e.g.: 22.1.5) asdf install erlang 22.1.5
These options will disable Java-related features and point to the correct OpenSSL paths.
