Installing Ruby on Rails behind a firewall

Rails
1

Ok,

I went to the “Get Ruby on Rails …” web page and followed directions.

When I get to the step where I’m to do this:

gem install rails --include-dependencies

I get this error:

ERROR: While executing gem … (SocketError)
getaddrinfo: no address associated with hostname.

Here is my configuration,

Win XP Pro

Running commands in a cygwin “bash” sh.

And I AM behind a firewall - meaning in my brower I use a proxy server
for all outside access.

Can anyone help me make the install work ?

Thanks in advance.

in a dos shell, you should “set http_proxy” to whatever you proxy is.

An other (boring) way is to download the packages 1 by 1 from rubyforge
(you
type gem install rails, and it will tell you what’s missing).

Am other way is to use instant rails.

gem install -p http://proxy.proxy:3128 rails --include-dependencies

I tried this too, and it started to work, but then got the same error.
Perhaps not all code down the line, sees that -p argument.

I’ve got the same problem where I’m working at the moment. No mix of
magic proxy incantations seems to let me ‘gem install’, while I can
happily do all sorts of other Internet stuff without problems. I
think the issue is likely to be with the proxy config at work, rather
than any problem with Ruby/Rails/gem.

The way I got around it is by downloading and using Instant Rails,
then backing up to USB key each night, taking the key home, starting
Instant Rails at home, ‘gem update --include dependencies’, add any
new gems, then back to work with a fully updated setup.

Aside from being a bit frustrating, the approach is working fine. I
can download individual gems at work, which means I can update/add
things given sufficient time & patience to track down any
dependencies, but I find it easier just to bring the key home and
update it all while I’m doing something else.
