Cygwin Ruby and Windows Ruby?

cjl

3/19/2005 3:01:00 PM

Hey all:

I use cygwin, and installed ruby to mess around with it.

Can I also install the windows one-click-ruby-installer?

Will they interfere with each other?

Yes.

No.

I have both the versions along with SFU 3.5 version living happily under
one roof :-)

Hey all:

Well, I went ahead and installed the one-click installer, and I think
it screwed up my cygwin ruby, because now irb doesn't work anymore.

If I type irb at the command prompt, I get the following:

/usr/bin/ruby: No such file to load -- ubygems (LoadError)

Note, 'ubygems' is not a typo, that is how the error message is
printed.

Help, anyone?

OK:

If I type irb I get the error message I described in my previous post.

If I type irb and then <tab> for command completion, I see there is
both irb and irb.bat, and irb.bat works.

Also, somehow the one-click installer /bin directory got automatically
added to my cygwin path. How did that happen?

One Click Installer has now implemented the stupid idea to register
the global environment variable "RUBYOPT" which loads the rubygems.
This is for all ruby interpreters on your system. Even if they
are older 1.8.1 systems (which do not support rubygems by default).

The idea is really bad and one more sign that ruby is a little bit
immature at the moment. If rubygems is such a good project (and i
think it is), someone should integrate this into the ruby.exe file
instead overloading 'require' with the current quick and dirty
hack.

For you the advise: do a "export RUBYOPT=" and everything should work
again.

Lather:

Thanks for the info.

Are the one-click installer people aware that they screw-up cygwin?

Should I drop the a note?

By default, the one-click installer installs RubyGems and sets the
environment variable. If you uncheck that option, this will not happen.

Hi cjl,

I owe you an apology for leading into a sticky situation. I haven't
played with my Cygwin installation in a while and should have checked it
out before responding. Please accept my sincere apologies.
