I am using rvm on my ubyntu 11.10. My readline is not working, I tried ruby extconf.rb but it is not passed. Output is bellow:
$ ruby extconf.rb
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
I tried installing libncurses5-dev & libreadline5-dev
$ sudo apt-get install libncurses5-dev libreadline5-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package libreadline5-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
libreadline-gplv2-dev:i386 lib64readline-gplv2-dev:i386 libreadline-gplv2-dev
E: Package 'libreadline5-dev' has no installation candidate
What is the problem here? Can anyone help?
Same issue as here Readline errors prevent me running rails console
Under ubuntu you can use the system readline installation.
rvm uninstall ${YOURUBYVERSION}
sudo apt-get install libreadline-dev
rvm install ${YOURUBYVERSION} --with-readline-dir=/usr/include/readline
Substitute ${YOURUBYVERSION} with your desired ruby version.
I got the solution:
Run the command
rvm requirements
It shows the requirements and dependencies. Install those and reinstall the ruby on rvm
rvm remove 1.9.2
rvm install 1.9.2
It works!
For some reason I can't comment on @zzeroo's answer, but I want to draw attention to the fact that he's using
--with-readline-dir=/usr/include/readline
instead of
--with-readline-dir=$rvm_path/usr
I was banging my head against the wall for a long time and changing this fixed it for me.
Have you tried:
rvm pkg install readline
Then install ruby through RVM --with-readline-dir=$rvm_path/usr?

FWIW, I'd suggest giving rbenv + ruby-build a go, if you've never considered it. A lot less headaches than with RVM.
I've googled for a couple days, but no answers helps me, so my solution was:
Fully remove rvm How to remove rvm
Remove all ruby packages. First, find out which packages do you have:
dpkg -l | grep ruby
then make
sudo apt-get purge {PACKAGE}
where {PACKAGE} is package you want to remove ( for me there were ruby ruby1.8 ruby1.9.1 )
Then I made fresh installation of RVM Install RVM and installed ruby 1.9.2 with
rvm install 1.9.2
Now it should work!
I tried everything, but it didn't work. I had to do rvm implode (after having all the requirements installed) and then rvm install 1.8.7; rvm install 1.9.3 and it wor
