Ruby 1.9.2 and Rails 3 cannot open rails console

I have already installed rvm and ruby 1.9.2, both working properly. Using rvm version 1.10.2. I previously installed the rvm packages readline/zlib, but now I'm having big troubles with readline now. I'm trying to install ruby 1.9.3 in rvm, but I always end up having readline not found.

I tried to follow different solutions:

 rvm remove 1.9.3
 rvm pkg install readline
 rvm install 1.9.3 --with-readline-dir=$rvm_path/usr/ \
     --with-zlib-dir=$rvm_path/usr/

 rvm use 1.9.3
 rvmsudo gem install bundler
 bundle install (all gems installed fine)
 rails c / rails s 
 .rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/irb/completion.rb:9:in `require': \
     cannot load such file -- readline (LoadError)

I have libreadline-dev (version 6, the current one) installed (everything needed by those packages pretty much)

I also tried the following:

.rvm/src/ruby-1.9.3-p0/ext/readline]$ 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

.rvm/src/ruby-1.9.3-p0/ext/readline]$ ruby extconf.rb \
    --with-readline-dir=/home/claudiocontin/.rvm/usr/
 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

 .rvm/src/ruby-1.9.3-p0/ext/readline]$ ruby extconf.rb \
    --with-readline-lib=/home/claudiocontin/.rvm/usr/
 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

Makefile is not generated of course ...

 apt-get install libreadline-dev
 Reading package lists... Done

 libreadline-dev is already the newest version.

Ideas?

Answer 1

What I ended up doing is remove all the libreadline from rvm usr/lib/ path.

Installed libreadline5-dev package (.deb in this case) downloaded manually, because the new ubuntu distro has only libreadline6-dev as candidate.

went to rvm ruby 1.9.3 src and:

ruby extconf.rb --with-editline-dir=/usr/ --with-readline-dir=/usr/
make
sudo make install

Now works like a charm.

Very painful stuff :)

edit:

also keep in mind that readline uses also libeditline-dev now, you can disable manually when configure ruby readline , passing: --disable-libedit

 ruby extconf --disable-libedit

Answer 2

I tried to do rvm pkg readline, install ubuntu pkgs etc without any success. What worked for me:

gem install rb-readline

And add the following line to your Gemfile:

gem 'rb-readline'

Answer 3

I've always found getting RVM to play nicely with packages to be a bit of voodoo. A lot of times, it's about catching a dependency - I put together a script that I've had luck with in past, try this:

sudo apt-get install zlib1g-dev libssl-dev libsqlite3-dev libmysqlclient-dev imagemagick librmagick-ruby libxml2-dev libxslt1-dev build-essential openssl libreadline6 libreadline6-dev zlib1g libyaml-dev libsqlite3-0 sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison libpq-dev libpq5 libmysql-ruby libmysqlclient-dev

rvm pkg install autoconf
rvm pkg install zlib
rvm pkg install readline
rvm pkg install openssl
rvm pkg install iconv
rvm install 1.9.3
rvm use 1.9.3 --default
