问题
I have tried everything I can think of to get this to work, to no avail so here I am requesting suggestions on how to debug.
Firstly, runnning Ubuntu 11.10
Installed rvm:
$ bash < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
Installed readline using apt-get:
$ sudo apt-get install libreadline-dev
Check for readline install:
$ dpkg --get-selections | grep readline
lib64readline-gplv2-dev install
lib64readline5 install
libreadline-dev install
libreadline5 install
libreadline6 install
libreadline6-dev install
readline-common install
Install ruby, with readline support?
$ rvm install 1.9.2 --with-readline-dir=/usr
Here is rvm version:
$ rvm --version
rvm 1.9.2 by Wayne E. Seguin (wayneeseguin@gmail.com) [https://rvm.beginrescueend.com/]
Lets try the ruby shell:
$ irb
1.9.2 :001 > puts "add history"
add history
=> nil
1.9.2 :002 > ^[[A^[[A^[[A^[[A^[[A <------ PRESS UP ARROW DOES THIS
No, ok so if its not going to work with ubuntu's readline version??? lets try with rvm's own version of readline:
$ rvm pkg install readline

Ok, there's an error there, lets take a look:

And as expected irb isn't working with readline:

回答1:
Ubuntu 12.04 here: the answers here helped, but were also misleading.
If you're using Ubuntu 12.04, DO NOT pkg install readline, with or without --skip-autoreconf. After you've done that, either readline or zlib will be broken no matter what combination of switches you give to rvm install 1.9.3.
To get it to work, do the apt-get install that rvm requirements tells you to do, do a pkg uninstall readline and then do a simple rvm remove 1.9.3; rvm install 1.9.3
回答2:
I struggled with this same issue with Ubuntu 11.10.
In my case readline would seemingly compile properly if I used the following:
$ rvm --skip-autoreconf pkg install readline
as outlined at the bottom of http://beginrescueend.com/packages/readline/
However, when I invoked irb, I would get the normal error "Unable to require readline"
Finally, based on Shane's command line, I invoked the following:
$ rvm install 1.9.3 --with-readline-dir=$rvm_usr_path --with-iconv-dir=$rvm_usr_path --with-zlib-dir=$rvm_usr_path --with-openssl-dir=$rvm_usr_path
rather than the command mentioned at http://beginrescueend.com/packages/readline/
$ rvm install 1.9.2 --with-readline-dir=$rvm_path/usr
In my case version 1.9.3 was what I wanted. And finally irb came up with a functioning readline.
Thanks to everyone here for pointing me in the right direction.
回答3:
Ok, so this might seem pretty obvious, well it always is when you know the answer:
I gave up using RVM, and switched to rbenv - which I'm very pleased I did!
sudo apt-get install libreadline-gplv2-dev
CONFIGURE_OPTS="--with-readline-dir=/usr/include/readline --with-openssl-dir=/usr/local" rbenv-install 1.9.2-p290
This installed without error - and I'm still not convinced I need the gplv2 package as I've got libreadline6-dev installed. However that STILL didn't resolve my problem. It did remove RVM from the equation, and show me that despite my best efforts the IRB shell was refusing to use readline.
The answer came from reading through this great guide:
RubyTools.pdf
Inside my ~/.irbrc file I found:
IRB.conf[:USE_READLINE] = false
A quick update to:
IRB.conf[:USE_READLINE] = true
And I'm cooking on gas!!
Thanks for all the great answers and suggestion, I do appreciate your time.
回答4:
This solved my problem for rvm with Ruby 1.9.3
gem install rb-readline
回答5:
I had the same issue but I'm on 11.04 and from reading the link you gave https://github.com/wayneeseguin/rvm/issues/553
and from the info in peplins comment there I removed the autoreconf call that was added here
https://github.com/wayneeseguin/rvm/commit/94c301d
and now readline compiles without any errors. I added back in the autoreconf call after I had compiled readline before installing ruby again.
So this is how I got it work:
edit ~/.rvm/scripts/functions/pkg and delete the following:
if [[ "${rvm_skip_autoreconf_flag:-0}" == 0 ]] &&
which autoreconf >/dev/null 2>&1 &&
which libtoolize >/dev/null 2>&1 &&
[[ -f configure.ac || -f configure.in ]]
then
__rvm_run "$package/autoreconf" \
"autoreconf -is --force" \
"Prepare $package in $rvm_src_path/$package-$version."
fi
Compile readline and remove ruby (I used the ree_dependencies command but I'm not sure this is necessary):
rvm pkg install ree_dependencies
rvm remove 1.9.2
undo your deletion to ~/.rvm/scripts/functions/pkg
I then installed 1.9.2 with this command (again it's from the ree install which I'm not sure is necessary but this is what I used)
rvm install 1.9.2 --with-readline-dir=$rvm_usr_path --with-iconv-dir=$rvm_usr_path --with-zlib-dir=$rvm_usr_path --with-openssl-dir=$rvm_usr_path
and now all appears to work as it should, hope that helps someone.

My setup is ubuntu 11.10, RVM 1.10.2, ruby 1.9.3.
This readline problem was giving errors when running irb, and prevented running of the rails console due to the error:
'require': cannot load such file -- readline (LoadError)
The solution that worked for me was the one described by Bryan Larsen, i.e.
DO NOT pkg install readline, with or without --skip-autoreconf
Do the apt-get install that rvm requirements tells you to do, then
rvm --skip-autoreconf pkg uninstall readline
rvm remove 1.9.3
rvm install 1.9.3
Thx for the tip Bryan.

These steps fixed my problem (on a Lubuntu 12.04) after previously compiling ruby and continually getting the "compile readline missing" error anytime I ran:
sudo aptitude install build-essential openssl libreadline6 \
libreadline6-dev curl git-core zlib1g zlib1g-dev \
libssl-dev libyaml-dev libsqlite3-dev sqlite3 \
libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev \
automake libtool bison subversion
rvm pkg uninstall readline
rvm remove 1.9.3
rvm install 1.9.3

Unfortunately none of these worked for me. I ended up using the Quick Fix from http://beginrescueend.com/packages/readline/
That solved my problem.

You may try a workarround installing the package libreadline5-dev. I gess the libreadline6-dev is not working right now.

For me, it just worked out of the box with the latest verison of rvm. My steps
bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer )
according to rvm requirements:
apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion
rvm install 1.9.3
rvm

You can see it is work fine for me.
1 - don't forget to install libedit-dev
# dpkg --get-selections| egrep '(readline|libedit)'
libedit-dev install # <= BSD PACKAGE, not GNU, but... it is work fine to me
libedit2 install # the same story as previous
libreadline-dev install
libreadline5 install
libreadline6 install
libreadline6-dev install
readline-common install
2 - uninstall pkg readline
$ rvm pkg uninstall readline
3 - go to $rvm_path/src/ruby-#{version}/ext/readline and do
$ ruby extconf.rb; make; make install
4 - forget about headache

If you are using Bundler then the following might help:
echo "gem 'rb-readline'" >> Gemfile
bundle install
