I have installed

fxirb 0.3.1

any idea?

Are you on Windows? If you are on Windows and installed Ruby by
RubyInstaller then you will not find ri, that is why perhaps is not
working. Because RubyInstaller brings the API documentation in *.chm
And also FXRuby 1.6.0 is pretty old, use last version. Lars Kanis has
been fixxing lot of bugs since 1.6.0 until last version(I think is
And I don’t recommend to use last Ruby version, Ruby 2.1 sounds more
stable, I mean a few gems could be not updatted(or tested) for Ruby 2.2.

I have installed LAST FXRuby from gems…
how to instal lastlast ?

You should tell your operating system. If windows see what I wrote.

yes windows
I found ruby22*.chm

so how I can to run/read fxri ?

As long as I know, RI is an ancient tool for see documentation while
using irb. Luis L., maintainer of RubyInstaller decided to put RI
apart of the instalation pack a few years ago(more than 4 years), since
he’s already providing you with a very usefull *.chm file with all the
documentation, easy to read, easy to seek.
I’ll repeat, if you used RubyInstaller to install Ruby you are not
bringing RI with it. Maybe you can try to install it by your own, google
may help you. Regards.
