Hello,

Does anybody know how to deal with this gem problem ?

Thanks a lot in advance for your help.

After trying to run gem update the message is:

Do you have a working C compiler available ? The error message suggest that you don't

Hello. I have encountered a similar problem. I am running Windows XP
SP2. If you just want to skip hpricot and continue updating your other
installed gems, you can do that by renaming the gem specification file
for hpricot under this directory:

C:\Ruby\lib\ruby\gems\1.8\specifications

just look for this file: hpricot-0.6-x86-mswin32.gemspec

and rename it, in my case i renamed it to:
hpricot-0.6-x86-mswin32.gemspec.bak

i believe that hpricot-0.6-x86-mswin32.gemspec is the key to solving
this problem in windows but since i am also a noob to ruby, i guess
renaming this file will suffice for now. i believe the gem update
command looks into the gem specification file for update parameters. and
since for some reason the update will not work, i guess it is best to
"fool" gem update into believing that you do not have hpricot installed.

i think you can then manually install or update hpricot by using this
command:

gem install hpricot --platform mswin32 --source
http://code.whytheluckystiff.net

as gerson pointed.

but i think it would be better if we can sort of edit the gem
specification of hpricot so that it will point to this location when the
gem update command is issued. i just don't know how to do it. does
anybody know?

Hi Fred,

thanks a lot for your answer !

No, I don't think so. I am running this in a (minimal) Windows Vista
installation on Virtual PC (to easily correct for mistakes, as I just
started to learn ruby and rails).

I have not installed anything that would include a C-compiler.

Is there a special one to install to run with ruby ? And where would I
put it ? In the ruby folder ?

If a special one is not required, which one would you recommend ?

thanks a lot

Peter

I thought that hpricot had a pre-built binary gem for windoze?

Hey, that worked for me too! Thanks Axel for referring me here. I had
noticed this post yesterday while I was at work, but I forgot about it
by the time I got home.

Forgive me for being a noob, but is Gerson the famous _why?

Hi Philip,

could you tell me, please, what exactely you did; as for me - I am still
getting the same error (after doing successfully: gem install hpricot
--platform mswin32 --source http://code.whytheluckystiff.net)

I also tried the gem update --with-make-prog option, but something
is wrong with that option ( or the way I am putting it), its not
accepted.

Even though I downloaded and installed hpricot (as mentioned above) the
gem update fails as mentioned in my initial posting.

So maybe a detailed description of what you did might help ? --I hope !!

Hi Gerson,

thanks a lot for the tip, even though for me it was not the breakthrough
yet.

Best

Peter

Hi,

Visual C 6.0 won#t install in Vista (at least I can't) get it istalled.
Would anybody know how to do that (as VC 6.0 apparently can't deal with
the Vista environment)

Dear Axel,

thanks a lot for your help !!
I managed to install the hpricot, but when I am running a gem update
then it tries to update hpricot as well and the same error occurs. Is
there a command to explicitly exclude the hpricote update when running
gem update

(something like gem update --exclude hpricot) ??

As I started using ruby/rails only recently I am not completely familiar
with all the options. So far I started gem updates from inside the
console window.

Open the gems package manager and type in the following:
gem install hpricot --source http://code.whytheluckystiff.net

I was not aware, that there is a specific gem package manager (other
than calling gem update within the console window).
How would I start it up (which programm-name would I have to open /
doubleklick) ?

Dear Peter,

this might have to do with Vista wanting you to have administrator rights....
You can set them in "system preferences" or look here:

Not that I know of. Maybe you submit this as a feature request to the people
who maintain rubygems ? There's a special mailing list for rubygems developers
you could ask for that.
Otherwise,

gems list

will display all the gems you have installed. If they are not too many, you could
remove them by hand and install them, with the right parameters again.

with all the options. So far I started gem updates from inside the

I was not aware, that there is a specific gem package manager (other
than calling gem update within the console window).
How would I start it up (which programm-name would I have to open /
doubleklick) ?

There is a Ruby distribution for Windows called One-click-installer Ruby

http://rubyforge.org/projects/rubyinstaller/

This installs Ruby so that you can see a folder for it in the tree of your installed
programs. The default name will be Ruby-186-26. There's a subfolder RubyGems
and inside that, a RubyGems Package Manager application, which opens a console-like
window.

I'm not really sure whether there's any difference between managing rubygems from
there or from the Windows console (maybe some care is needed to tell the Windows console
where to find rubygems).

As a quick-and-dirty workaround, you might also try to write a rubygems-update-with-exclusion script using the console yourself ... maintain a text file with special parameters for special gems and use Ruby's 'system' command to invoke the console..you could then uninstall every gem in the list
given by 'gems list', and reinstall it, maybe from some special source, like in the hpricot
case, if your parameter file includes some special information.

Best regards,

Axel

Dear Axel

thanks a lot for your suggestion. The problem seems to be more
fundamental: at least when I try to install VC 6.0 within my VirtualPC
Vista I am getting an errror message (very early on during installation)
which must be somehow related to an address conflict. It seems that VC
6.0 is using 16 Bit addresses and Vista can't handle these ?!

Do you have any idea what to do ?

Dear Axel,

thanks a lot for your tremendous help !

In my ruby-folder I can't find a subfolder RubyGems.

Therefore, I installed ruby again from the link you gave (in a folder
ruby-186-26) and I checked the option for RubygGems during installation.

The new installation has the folders:
bin
doclib
man
samples
scite
share
src

and I can't find any RugyGems subfolder within these folders.
Did I do something wrong ?

Peter

Dear Peter,

did you try what's suggested here:

http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=3328605&SiteID=1 ?
(there is a promising 4-link post in there somewhere...)
I had VC 6.0 installed on another computer under Windows XP a longer time ago,
with no Vista-related problems, of course.
Please tell me what you find out.

Best regards,

Axel

Dear Axel,

well, I found RubyGems, but not as a subfolder but within the start
menue (ruby-186-26 => RubyGems

Here I can indeed start the Gems console (for some reason this
start-menue structure did not install with my previous ruby
installation, even though I used the same exe-program to install (but
there the install folder was ruby oposed to the new one ruby-186-26).

Until now, I was using the console of Aptana radrails, as I had no
access to some other one (and the windows console did not really work).

Now I will try from here and get back as soon as I know more.

Dear Axel,

the bottom line seems to be: MS VC 6.0 does not run under Windows Vista
!

Too bad, I have already invested too much time trying to get this
running.

But other people seem to use Ruby with Vista, so there must be some
other way (other than using MS VC 6.0 ) ?
