RVM - MacPorts won't update through proxy - ruby

Question

I'm trying to use RVM to install ruby on my iMac.
I start by typing the following:
rvm list known
I then target the version that I want to install (the guide I'm following recommends 1.9.2 instead of the base 1.8.7) with the following line:
rvm install 1.9.2
Then I get this:
27698AM:~ butler15$ rvm install 1.9.2
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.7/x86_64/ruby-1.9.2-p320.
Continuing with compilation. Please read 'rvm mount' to get more information on binary rubies.
Installing requirements for osx, might require sudo password.

I enter my password and I get this:

If I understand correctly it's trying to update MacPorts but fails due to being behind a proxy (or something?)
I've tried following this guide but it didn't work: http://samkhan13.wordpress.com/2012/06/15/make-macports-work-behind-proxy/
Further Information:
My current version of RVM and RUBY: http://d.pr/i/H1Eu
My OSX - 10.7.4
Thanks in advance for your help :)

Answer 1

While Koji's comment makes RVM work behind a proxy, Macports will need to be updated to automatically work behind a proxy as well.
First, install macports from the package at http://www.macports.org/install.php
Then run the following commands:
sudo mkdir -p /opt/local/var/macports/sources/svn.macports.org/trunk/dports/
cd /opt/local/var/macports/sources/svn.macports.org/trunk/dports/
sudo svn co http://svn.macports.org/repository/macports/trunk/dports/ .
In /opt/local/etc/macports/sources.conf comment out
rsync://rsync.macports.org/release/tarballs/ports.tar [default]
with your favorite editor and then add this right below that line.
file:///opt/local/var/macports/sources/svn.macports.org/trunk/dports/ [default]
And then run these commands so that it updates and doesn't complain about your ports not being indexed.
sudo port -d sync
sudo portindex
Then modify .rvm/scripts/functions/requirements/osx_port by changing selfupdate to sync in the requirements_osx_port_update_system() function.
requirements_osx_port_update_system()
{
#__rvm_try_sudo port -dv selfupdate || return $?
__rvm_try_sudo port -dv sync || return $?
}

If you are trying MAKE MACPORTS WORK BEHIND PROXY, How about avoiding port selfupdate?
$ diff -u .rvm/scripts/functions/requirements/osx_port.org .rvm/scripts/functions/requirements/osx_port
--- .rvm/scripts/functions/requirements/osx_port.org 2013-05-28 16:58:37.000000000 +0900
+++ .rvm/scripts/functions/requirements/osx_port 2013-05-28 16:58:50.000000000 +0900
## -82,7 +82,7 ##
requirements_osx_port_update_system()
{
- __rvm_try_sudo port -dv selfupdate || return $?
+ __rvm_try_sudo port -dv sync || return $?
}
requirements_osx_port_define()
In my case, it works fine.

Answer 3

run "__rvm_try_sudo port -dv selfupdate" in terminal and type in password by keyboard
then re-run the script to install ruby
It works on my laptop
Good luck

You need to (re)install the command lines tools first:
sudo xcode-select --install
then, update macports:
sudo port -v selfupdate

Then, you might be missing some requirements so do:
sudo rvm requirements
