gem (update ?) problem

[Peter Krieg]

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:
gem update

ERROR: While executing gem ... (Gem::Installer::ExtensionBuildError)

Hello,


Does anybody know how to deal with this gem problem ?

Thanks a lot in advance for your help.

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

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

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

Hi Peter,

Try this command:

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

Hi Peter,

Try this command:

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

Gerson.

Gerson,

That worked for me on Windows Vista Home Premium.

Thanks for the tip!

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.

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 Peter,

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

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 ?



Best regards,

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

 

[Peter K.]

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 ) ?

Hello,


Does anybody know how to deal with this gem problem ?

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?

 

[John Clancy]

This worked for me:

1 gem uninstall hpricot

2 gem update

3 gem install hpricot --platform mswin32 --source
