Annoyance with gems and zlib


#1

Hi … i’ve been trying to get rails up and running on my system. I run
OS X leopard. updated ruby to 1.8.7. Installed ruby 1.9 with a suffix
following this guide (http://ruby.tie-rack.org/28/installing-19/)

So I checked what rails version I had … turns out to be 1.2.6 iiiiik

Quickly typed the following:

mbp:~ spobo$ gem update rails -v

And got this awesome result.

Updating installed gems
GET 302 Found: http://gems.rubyforge.org/latest_specs.4.8.gz
GET 200 OK:
http://guide.opendns.com/?url=gems.rubyforge.org%2Flatest_specs.4.8.gz&servfail
ERROR: While executing gem … (Zlib::GzipFile::Error)
not in gzip format
mbp:~ spobo$

so … anyone have any clues? I’m sort of really stumped as to what goes
where when you compile programs like ruby as to what goes where and how
do you tweak/uninstall it when necessary.

ps:

mbp:~ spobo$ sudo gem update --system
Updating RubyGems
ERROR: While executing gem … (Zlib::GzipFile::Error)
not in gzip format

ps2: yes, I know I’m not using ruby 1.9 when I do the simple gem command
and no, gem19 install rails and gem19 update --system do the same.

did you even try clicking the above link?

you are having dns issues. either that, or gems.rubyforge.org was
down when you ran that command. first step is always to read the
error messages! :wink:

Well … to tell the truth I only got that reply once. The 90 other
times everything just said not in gzip format without anything else. I
was hoping it was more of a quick fix and a known issue. I’ll try
turning off opendns and see what happens then.

Did you try fetching either URL (using wget or curl or telnet)?

It seems that opendns breaks the internet on purpose. I would avoid
it at all cost.

I completely agree. Turned off opendns and everything started working
magically. Who knew … perhaps the guys running opendns are Java
fanboys? Also, rails was using a different version of ruby which led to
some incompatibilities between rubygems and rails. Everything is fixed
now and running smoothly with phusion passenger … brilliant :stuck_out_tongue: Off to
do some conding!

Nah, they just hate the Internet. Maybe they’re Flash fanbois?

However, it is possible to register an IP address to not use this
“feature”:

Not great, but it works, if your ISP-provided DNS is really bad enough
that
you need OpenDNS. If not, easier to just turn it off.
