I want to use rails console and I'm using ubuntun 11.10 currently I have found the issue
error is something :
completion.rb:9:in `require': no such file to load -- readline (LoadError)
and I found a way to solve it:
http://blog.jasonmeridth.com/2010/11/25/readline-error-with-rvm-and-rails-3.html
but seems in ubuntu 11.10 the libreadline5-dev is missed and it is replaced with version 6
I installed version 6 and also I get the version 5 from
https://launchpad.net/ubuntu/oneiric/i386/libreadline-gplv2-dev/5.2-9ubuntu1
but yet if I try to run following code :
ruby extconf.rb
I'll get following lines :
checking for tgetnum() in -lncurses... yes
checking for readline/readline.h... yes
checking for readline/history.h... yes
checking for readline() in -lreadline... no
checking for readline() in -ledit... no
checking for editline/readline.h... no
the "no"s part is my problem , so how can I solve this problem?
Ubuntu 11.10 uses newer readline library which not in sync with the readline package offered by rvm
To solve this (assuming you use single-user installation of rvm) do:
1) ensure you have installed ubuntus readline and editline dev packages
sudo apt-get install libreadline6 libreadline6-dev
2) configure ruby's readline extension to use the systems libs, not rvm's packages
rvm pkg uninstall readline
cd ~/.rvm/src/ruby-1.9.2-p290/ext/readline
ruby extconf.rb --with-editline-dir=/usr/ --with-readline-dir=/usr/
make
make install
3) go to your project and start up the rails console
Tip: You can call
rvm requirements
to see what ubuntu packages should be installed to use rvm ruby
