This is a quite common question asked, how to generate a standalone executable of your Ruby script.

There are several approaches and each one have its complexities, downsides and others.

A common one is usage of Ocra:

https://github.com/larsch/ocra

Which wraps your script, it's dependencies and Ruby into a single package that gets self-extracted on invocation.

Pros: easy to get started, simpler to get working and works across different versions of Ruby.

Cons: attempt to use with applications that open ports (like a web server) will trigger Windows Firewalls alerts on every execution.

Extracting the contents of Ruby, gems and other dependencies on every run might result in the perception of slow startup/execution.

Exerb:

https://github.com/luislavena/exerb-mingw

Is a port of Exerb, a Japanese tool that is tailored at packaging *just* enough code to produce a native executable. It doesn't extract contents into temporary folders like Ocra, but requires a higher understanding of Ruby, compilers and how gems work to produce a standalone executable.

Is not very common compared to Ocra, but still a valid option.

I recommend you start with something like Ocra right now (since I don't know your requirements) and if you need something more customized, then you can start researching Exerb.

Hi Luis,

Have you tried releasy (https://github.com/Spooner/releasy/)? I haven't, but according to the docs, it gives more options for Windows packages than the Ocra approach.

I have no experience with releasy, but seems to be a installer and not a packager.

Seems similar to Chef omnibus which bundles Ruby, your gems and everything into an installer, not generating a single executable that can be executed without installation.

For a real-life example of Chef omnibus installer, see Vagrant, which uses Ruby, gems and other stuff to provide a simple command line tool, but doesn't package everything into a single exe.

Cheers,
