RVM - ReadLine Support

[Jim Kirkbride]

Hi All,

I'm getting started with the Conclave project, and I've run into a speed bump with ReadLine support.  The message I'm getting is:

You're running a version of ruby with no Readline support
Please `gem install rb-readline` or recompile ruby --with-readline.

I'm running Ubuntu 12.04, rvm 1.10.0.   'bundle install' runs successfully without any complaints, and I've tried the whole gem install rb-readline, as well as removing Ruby 1.9.2 via RVM ('rvm remove 1.9.2' followed by 'rvm install 1.9.2 --with-readline-dir=/usr/include/readline').  I've also wiped out my gemsets and gems in my .rvm directory to no avail.  

I'm more than comfortable on the command line, but I've googled around quite a bit but I'm not having any luck with the suggested solutions.   I figure there are probably at least a couple of Ruby newbs out there beside myself that are running into the same issues so I wanted to get your input.  Any help would be appreciated as I would really like to learn more and contribute to this project.  Let me know if you have any questions or concerns and thanks in advance!

You have to install the non-ruby deps. Look at `rvm requirements`

Hi Isaac,

Thanks for the reply.  I probably should've mentioned that I have done that as well:

Hi Isaac,

Thanks for the reply.  I probably should've mentioned, I've done that as well:

<me>@magi-2:~/projects/conclave$ rvm requirements
Requirements for Linux ( DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=12.04
DISTRIB_CODENAME=precise
DISTRIB_DESCRIPTION="Ubuntu 12.04.1 LTS" )
NOTE: 'ruby' represents Matz's Ruby Interpreter (MRI) (1.8.X, 1.9.X)
             This is the *original* / standard Ruby Language Interpreter
      'ree'  represents Ruby Enterprise Edition
      'rbx'  represents Rubinius
bash >= 4.1 required
curl is required
git is required (>= 1.7 recommended)
patch is required (for ree and some ruby-head's).
To install rbx and/or Ruby 1.9 head (MRI) (eg. 1.9.2-head),
then you must install and use rvm 1.8.7 first.
NOTE: To all Multi-User installers - DO NOT forget to add your users to the 'rvm' group.
      The installer does not auto-add any users to the rvm group. Admins must do this.
      Group memberships are ONLY evaluated at login time. Log them out, then back in.

These are the packages I install for a clean CentOS box, maybe there is something relative to Ubuntu that you need?

yum install gcc git autoconf automake bison bison-devel ruby zlib-devel openssl openssl-devel gcc-c++ curl-devel zlib-devel pcre-devel libxml2 libxml2-devel libyaml libyaml-devel libxslt libxslt-devel readline readline-devel patch make redis mysql mysql-devel mysql-server

I've run into this before.

One of the dependencies has to be there befor you compile ruby. Perhaps, you installed rvm/ruby, then installed os dependencies?

Try removing all your rvm rubies, and reinstalling/compiling them.

Jon,

Entirely possible.  I'll try a clean install of RVM and Ruby 1.9.2 (and hopefully not bork my 1.8.7 install in the process) and see how that goes. 

Thanks,

Jim

rvm remove ruby-1.9.2

rvm install 1.9.2

should force the re-compile. rvm is just a bunch of shell tricks, so you shouldn't need to remove/reinstall rvm itself.

Did this solve the problem for you? Just curious

Giving it a shot tonight, got caught up the family and my business website (Ruby 1.8.7/Rails 3, which I strangely do not have ReadLine issues with).

Update, got it working. 

1.) Completely purged rvm from my system ('rvm implode' and remove any references to rvm from .bash_profile, .bashrc, etc)

2.) Install RVM (on Ubuntu 12.04 for a single user): 

curl -L get.rvm.io | bash -s stable --auto 

source $HOME/.rvm/scripts/rvm

rvm install 1.9.2

That was it, I'm able to run rake and rails just fine now.

Thanks to everyone for the assistance!
