a n00b's journey
sudo apt-get install msttcorefonts
sudo apt-get installNext step was to run curl to do the basic install of rvm:
curl
git-core
build-essential
zlib1g-dev
libssl-dev
libreadline5-dev
bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head )Then I edited .bashrc and commented out the line
[ -z "$PS1" ] && returnI noticed I had made a mistake when adding the source line to .bashrc on the Acer. The line should be
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"After that, I executed .bashrc like this
. ./.bashrcand when I ran
type rvm | head -n1I got the response
rvm is a functionjust as the original instructions said to expect.
rvm install 1.9.2and it downloaded and installed ruby 1.9.2 and rubygems 1.3.7.
rvm --default 1.9.2then ruby -v said "ruby 1.9.2p0..." and gem -v said "1.3.7".
[ -z "$PS1" ] && returnin .bashrc to see if my guess was right about reinstating it after rvm had been used once. I closed the Terminal window and opened a new one, and ruby -v still worked. I logged out and in again, and ruby -v still worked.
sudo dpkg -i skype-ubuntu-intrepid_2.1.0.81-1_amd64.debThe installer complained of missing dependencies. I tried apt-get install on the exact names of packages the installer listed:
sudo apt-get installUbuntu could find no installation candidate for any of these packages.
lib32stdc++6
lib32asound2
ia32-libs
libc6-i386
lib32gcc1
cd /etc/aptand edited the file, adding the repository at the end.
sudo cp sources.list sources.list.backup
sudo apt-get updatebut the update complained that it could not find http://download.skype.com/linux/repos/debian/dists/stable/non-free/binary-amd64/Packages.gz.
sudo apt-get install lib32stdc++6This time it complained about unmet dependencies, and suggested running this:
sudo apt-get -f installThis did quite a lot, including installing or updating all the dependencies the dpkg command had complained about. It took a while.
ext4 30.0 GB / /dev/sda1The installation went smoothly. I restored /home from the backup.
ext4 362 GB /home /dev/sda6
swap 8 GB /dev/sda5
sudo apt-get installThen, I downloaded the latest Instiki from http://instiki.org/ and unpacked the tarball.
libxml2-dev
libxslt1-dev
sqlite3
libsqlite3-dev
gem install sqlite3-ruby
Bundler couldn't find some gems. Did you run 'bundle install'?This hasn't happened before in my experience, so I assume it has something to do with running ruby under rvm vs. running it native.
ruby bundleNo complaints, so I started Instiki and it came up clean.
apt-get installI then proceeded to make a series of noob mistakes, and after cleaning off various partial and incorrect installs, this is how I got rvm working. The official installation instructions at http://rvm.beginrescueend.com/rvm/install/ are pretty good, but are not exactly right.
curl
git-core
build-essential
zlib1g-dev
libssl-dev
libreadline5-dev
bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head )This step appeared to work. The author, Wayne Seguin, kindly included the following advice in the console output: "Be sure to get head often as rvm development happens fast." Sound advice.
rvm notesto install dependencies, but in fact it only displays a description of dependencies.
[ -z "$PS1" ] && returnand they recommend wrapping this in an if structure so that rvm will work correctly. I found that after completing the rest of the installation steps, rvm never worked. It turned out that this change is required only for the installation process, and once rvm has been installed you should reinstate the original statement. I changed it to
if [[ -n "$PS1" ]] ; thenand afterwards changed it back to
return
fi
[ -z "$PS1" ] & returnThe installation instructions also say to put this line at the end of .bashrc:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"They then say you have to run
source ~/.rvm/scripts/rvmthe first time you use rvm. In fact, you have to run this command every time you want to use rvm. I added the source command to the end of .bashrc, and rvm now works properly.
type rvm | head -n1and it should display
rvm is a functionThen, you run the source command for the first time. In fact, that results in
rvm is hashed (/usr/local/bin/rvm)You have to run the source command first, and then rvm will be a function.
rvm install 1.9.2and then to make 1.9.2 the default version of ruby (as far as rvm was concerned, anyway):
rvm --default 1.9.2Good news: It installed rubygems automatically.
wubi --32bitThe installer recognized that Ubuntu was already installed and offered to remove it. I chose Yes, the installer removed Ubuntu 9.10, and exited. I ran the command a second time, exactly the same way, and this time it downloaded the installation files and proceeded with the installation. This took quite a while, but completed without any problems.
