How To Fix ocamllex.byte: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu ocamllex.byte is provided by ocaml package.

ocaml is:

Objective Caml (OCaml) is an implementation of the ML language, based on the Caml Light dialect extended with a complete class-based object system and a powerful module system in the style of Standard ML.

OCaml comprises two compilers. One generates bytecode which is then interpreted by a C program. This compiler runs quickly, generates compact code with moderate memory requirements, and is portable to essentially any 32 or 64 bit Unix platform. Performance of generated programs is quite good for a bytecoded implementation: almost twice as fast as Caml Light 0.7. This compiler can be used either as a standalone, batch-oriented compiler that produces standalone programs, or as an interactive, toplevel-based system.

The other compiler generates high-performance native code for a number of processors. Compilation takes longer and generates bigger code, but the generated programs deliver excellent performance, while retaining the moderate memory requirements of the bytecode compiler. It is not available on all arches though.

This package contains everything needed to develop OCaml applications.

To fix this problem, we can install more using the command below.

sudo apt-get -y install ocaml

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install ocaml.

sudo apt -y install ocaml

Or if you have aptitude installed you can use the following command.

sudo aptitude install ocaml
