I installed ruby on Ubuntu 8.1 in the following manner
removed all ruby files using locate
sudo apt-get install readline5-dev build-essential autoconf wget
libreadline5-dev libncurses5-dev zlib1g-dev libsqlite3-dev libssl-devsv
libncurses5-dev libssl-dev checkinstall
mkdir -p /usr/local/src && cd /usr/local/src
wget ftp://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.1-p0.tar.bz2
tar -xjvf ruby-1.9.1-p0.tar.bz2
cd ruby-1.9.1-p0
.sudo ./configure --prefix=/usr --enable-pthread --enable-shared
#perhaps
i should have added -with-readline-dir=/usr/local
sudo make
sudo checkinstall found everything to be OK
IINSTALLING GEMS
sudo gem sources -a http://gems.github.com
sudo gem install rack rake # It seems that you need to install rack
before
installing actionpack and rails requires rake"
sudo gem install rails actionpack activesupport activerecord
activeresource
actionmailer # sudo gem install rails didn’t install activesupport and
some
other packages
Now all of this seems to work fine. However, when I install other gems,
I
usually receive the following error message
sudo gem install sinatra
Successfully installed sinatra-0.9.1
1 gem installed

ERROR: While executing gem … (TypeError)

Googling on ‘can’t convert Pathname into String’ doesn’t turn up much.
Does
anyone have any ideas about this?
