Ruby Version Manager - allows switching between versions of ruby, gems, rails etc.
RVM installation
First install RVM (Ruby version manager). This will download the source and compile the necessary tools, and will also allow to switch between different versions, for example, ruby-1.8 and ruby-1.9.2.
sudo apt-get install curl git-core bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head )
RVM tells you to update your .bashrc. Add the following at the end of the file:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
RVM is also concerned if you have any 'return' in your .bashrc script. Replace it using if and fi as in the RVM comments after its installation. Comment the first line below and add the second. Then add fi at the end of the file.
# [ -z "$PS1" ] && return if [[ -n "$PS1" ]] ; then
Upgrading RVM
Either from the latest gem
rvm update
Or from the head version in repository
rvm get head
Do not forget to reload it or reopen the terminal
rvm reload
Configuration management
How to check the current configuration
rvm use
Switch to the default configuration
rvm use system
Switch to another (1.9.2@rails3) configuration
rvm use 1.9.2@rails3
Create a new (1.9.2) configuration with a (rails3) gemset
rvm use --create 1.9.2@rails3
Making the configuration default
rvm use 1.9.2@rails3 --default
Ruby 1.9.2 and Rails3 (example setup)
Install Ruby 1.9.2
rvm 1.9.2
Create Rails 3 gemset and switch to it:
rvm use --create 1.9.2@rails3
Install gems
Sqlite3
sudo apt-get install sqlite3 libsqlite3-dev gem install sqlite3-ruby
Mysql
sudo apt-get install mysql-server libmysqlclient15-dev gem install mysql
Postgres
(note, the newer gem is "pg", not "postgres"!)
sudo apt-get install postgresql-server-dev-8.4 gem install pg
Rails 3
gem install rails rails --version
...or without "ri" and "rdoc" documentation (faster)
gem install rails --no-ri --no-rdoc
Other gems as needed
gem install ...
Test and Done
Test your installation by making a test application
rails new tetsApp cd testApp rails server
Now check the http://localhost:3000 in your browser. Rail on.
