Unable to preload "rbconfig" in my irb session

Ruby
1

I’m using Ruby 1.9.2 with Windows XP as host, I ran the command

irb --simple-prompt -rrbconfig

from the command line and got an error stating:
“E:/Ruby192/lib/ruby/site_ruby/1.9.1/rbreadline.rb:2043:in ``’: No such
file or directory - stty -a (Errno::ENOENT)”

I’ve attached the complete error statement along with the post, please
help.

Thanks,
Sandeep

Have you installed cygwin or cygwin installation bundled with E text

What is the output of “SET TERM” ?

This has nothing to do with rbconfig but instead if the rb-readline
(pure-ruby readline) component that is bundled with Ruby 1.9.2-p0
provided by RubyInstaller.

The only way for stty be invoked is an incorrect environment variable
or bash/sh installation interfering with rb-readline.

I’m not able to recreate this:

C:\Users\Luis>ruby -v
ruby 1.9.2p0 (2010-08-18) [i386-mingw32]

C:\Users\Luis>set TERM
Environment variable TERM not defined

C:\Users\Luis>irb --simple-prompt -rrbconfig

Please provide that information and also open a bug report in rb-
readline issue tracker:

C:\Documents and Settings\Scarlet Pimpernel>ruby -v
ruby 1.9.2p0 (2010-08-18) [i386-mingw32]

C:\Documents and Settings\Scarlet Pimpernel>set TERM
TERM=nutc
TERMCAP=E:\RATIONAL\RATION~1\NUTCROOT\etc\termcap
TERMINFO=E:\RATIONAL\RATION~1\NUTCROOT\usr\lib\terminfo

I’m using a normal command prompt and as I’m yet a beginner I do not
know what you mean by: “The only way for stty be invoked is an incorrect
environment variable or bash/sh installation interfering with
rb-readline.”

Thanks,

Can you unset TERM?

I searched a bit looking for what could be considered a “nutc”
terminal option and nothing was found. Also dunno what could have set
that for you.

As I indicated in the ticket, please unset it:

SET TERM=

And try again.

stty is a utility in *nix systems used to determine terminal
capabilities. Due the weird terminal setting you have, it is trying to
use stty which is not found.

I mentioned that a cygwin installation or something is interfering in
your system, which with the above that you provided proven correct.

It seems that the rbreadline.rb distributed with rubyinstaller 1.9.2
is not a bug fixed version.

Park, do you consider current rb-readline is candidate for a release?

That way I can provide packages and installation instructions to
users.

Thank you

i have unset the TERM.

Now, when i execute the “set TERM” command, i get:

C:\Documents and Settings\Scarlet Pimpernel>set TERM
Environment variable TERM not defined

Please provide me with the correct environment variable settings.

Thanks,
Sandeep.

Yes, at least, the current version is better than the installer
included version.

That way I can provide packages and installation instructions to
users.

does that mean, I should uninstall my current version of the ruby and
opt for an older one or is there a better way out?

Thanks,

Provided instructions for you in the rb-readline ticket:

Will perform a release and instructions soon.

rubyinstaller 1.9.2 version:

def no_terminal?
term = ENV[“TERM”]
term.nil? || (term == ‘dumb’) || (term == ‘cygwin’ &&
RUBY_PLATFORM =~ /mswin|mingw/)
end

the latest github version:

def no_terminal?
term = ENV[“TERM”]
term.nil? || (term == ‘dumb’) || (RUBY_PLATFORM =~ /mswin|mingw/)
end
