Go to OCaml.org and follow the instructions to install the latest version of OCaml.
I recommend that you install opam
as well.
Optional but highly recommended:
Install ledit
for more convenience when using the OCaml interpreter.
You can install ledit
by running
opam install ledit
It may be available in your favorite package manager as well. E.g.
brew install ledit
Once installed, add the following line to your
~/.bash_profile
or ~/.bashrc
file:
alias ocaml='ledit ocaml'
