Rails 3: Routing Examples

Rails 3: Routing Examples

11 Oct 2010

Note when installing Rails3 with RVM


- ruby >= 1.8.7 but p248 and p249 crashes rails3

- gem >= 1.3.6

My environment

- Ubuntu
$ cat /etc/lsb-release

- Rvm
$ rvm -v
rvm 0.1.44 

To update your rvm to the latest version run the following command;
$ rvm update

Since the version of ruby gems in my environment (Ubuntu karmic) is 1.3.5, I decided to use RVM and install ruby 1.8.7 (for a compatibility of other applications) and use rubygem 1.3.7.


$ rvm notes
Notes for Linux ( DISTRIB_ID=Ubuntu

*  NOTE: MRI stands for Matz's Ruby Interpreter (1.8.X, 1.9.X), ree stands for Ruby Enterprise Edition and rbx stands for Rubinius.

*  curl is required.

*  patch is required (for ree, some ruby head's).

*  If you wish to install rbx and/or any MRI head (eg. 1.9.2-head) then you must install and use rvm 1.8.7 first.

*  For JRuby (if you wish to use it) you will need:
$ aptitude install curl sun-java6-bin sun-java6-jre sun-java6-jdk
*  For MRI & ree (if you wish to use it) you will need (depending on what you are installing):
$ aptitude install build-essential bison openssl libreadline5 libreadline-dev curl git-core zlib1g zlib1g-dev libssl-dev vim libsqlite3-0 libsqlite3-dev sqlite3 libreadline5-dev libreadline6-dev libxml2-dev git-core subversion autoconf
*  For IronRuby (if you wish to use it) you will need:
$ aptitude install curl mono-2.0-devel

It is recommended to install the following packages beforehand because, without these, I encountered errors saying 'no such file to load' by ruby.

$ rvm pkg install iconv 
$ rvm pkg install readline 
$ rvm pkg install zlib
$ rvm pkg install autoconf
$ rvm pkg install openssl

$ export PATH=$HOME/.rvm/bin:$PATH

# To list all rubies you can install;
$ rvm list known

$ rvm install ruby-1.8.7-p299  -C --with-readline-dir=$HOME/.rvm/usr --with-iconv-dir=$HOME/.rvm/usr  --with-zlib-dir=$HOME/.rvm/usr --with-openssl-dir=$HOME/.rvm/usr

$ rvm use 1.8.7 && ruby -v
info: Using ruby 1.8.7 p299
ruby 1.8.7 (2010-06-23 patchlevel 299) [i686-linux]

$ gem -v

If you got an error like bellow, one of packages above may not be correctly installed.
$ bundle exec rails c production
/home/suzukimilanpaak/.rvm/rubies/ruby-1.9.2-p290/lib/ruby/1.9.1/irb/completion.rb:9:in `require': no such file to load -- readline (LoadError)

If this's the case, execute following commands to reset ruby with newly compiled packages
rvm remove 1.9.2 
rvm cleanup all
rvm pkg install readline
rvm install ruby-1.9.2

Install Rails3 (Do not sudo when you using RVM, which will cause a permission denial or unreachable path when running console, a server and a rake task in your user privilege)
$ gem install rails -v 3.0.0

Got this notice by rails -h
$ rails -h

Could not find gem 'mysql2 (>= 0, runtime)' in any of the gem sources.
Try running `bundle install`.

Create a new application

$ rails new apns

$ rails server
