I'm using Ubuntu 8.10 and I installed Ruby and Ruby on Rails following the directions on this site. The exact directions I followed are no longer there as it appears the rubyonrails.org wiki has changed recently. But I installed it the long way. Installed Ruby, then Gems, then installed Rails using "gem install rails".
I haven't really messed with Rails for a while, and I tried to use the Gem command today and...
The program 'gem' can be found in the following packages:
* rubygems1.8
* rubygems1.9
Try: sudo apt-get install <selected package>
bash: gem: command not found
That's just weird to me because I installed rails using the gem command. I have been seaching my computer for the gems binary so I could create a link to it in the bin directory but I can't find it. I know it's installed becaues when I run 'script/server' and go to localhost:3000 in a browser I get the following version information:
Ruby version 1.8.7 (i486-linux)
RubyGems version 1.3.1
Rails version 2.2.2
Active Record version 2.2.2
Action Pack version 2.2.2
Active Resource version 2.2.2
Action Mailer version 2.2.2
Active Support version 2.2.2
Anyone know how I can get my gem command working again? Thanks for any help.
Note: I am new to Rails and fairly new to Ubuntu and Linux in general.
Did you install rubygems from apt-get? If yes, maybe you should try to remove it and install it from source.
Here is another article on installing Rails on Ubuntu:
http://www.rubyinside.com/how-to-install-a-ruby-18-stack-on-ubuntu-810-from-scratch-1566.html
Essentially, you can install Ruby from apt-get or source, but it's recommended to install rubygems from source.
You could look to see if it's in:
/usr/bin/gem1.8
if it is, then symlink /usr/bin/gem to it:
sudo ln -s /usr/bin/gem1.8 /usr/bin/gem
BTW, here's another tutorial on how to install rails on Ubuntu 8.10:

I have a friend's website code, which is in Ruby on Rails.
I have tried to install RoR on my Mac using instructions at gorails.com
OS : Mac Mojave
ruby -v : ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-darwin18]
rails -v :
/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems.rb:241:in `bin_path': can't find gem railties (>= 0.a) (Gem::GemNotFoundException)
from /usr/local/bin/rails:22:in `<main>'
What I tried : I installed ruby, and then rails, using gorails tutorial, and kept getting errors stating version number mismatch.
Keep in mind that creating a new app, worked, but trying to run this existing code is a problem.
So then I uninstalled everything and updated the version using rvm, and since then I am getting this error.
When I cd into the webapp folder and run bundle install, I get errors, such as:
zsh: /Users/abc/.rvm/gems/ruby-2.2.3#hs/bin/bundle: bad interpreter: /Users/abc/.rbenv/versions/2.5.3/bin/ruby: no such file or directory
Could not load OpenSSL.
You must recompile Ruby with OpenSSL support or change the sources in your
Gemfile from 'https' to 'http'. Instructions for compiling with OpenSSL using
RVM are available at rvm.io/packages/openssl.
This project uses a PostgreSQL database, which I have setup already.
If required, I can share the gemfile of this project too.
What is the best way to get this project working?
Am I missing something crucial?
You can't run RVM and RBENV on the same machine. Pick one and remove the other. You're probably best to uninstall both and then pick one, start over.
Uninstall RBENV instructions here or in your case probably brew uninstall rbenv
Uninstall RVM see How can I remove RVM (Ruby Version Manager) from my system?
Close all terminals and then start a new one.
Install RVM see https://rvm.io/rvm/install
Then go to your project, make sure you have the correct ruby version needed by your project. If not, you will need to install with rvm install 2.5.1 for example.
Then run
rvm use 2.5.1 #or some other version
Then you should be able to run bundle install
The rest of the instructions in your link should be ok.
Accidently I have installed both versions of ruby on my system and now the default version is set to
$ ruby -v
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]
but I need to set the default version to 2.0.0...
for this I used the command
$ rvm 2.0.0p294 --default
but it says rvm is not currently installed though I installed it, typing various commands(via google) .
Also I want to install an Integrated Ruby shell in ubuntu 13.04, do suggest how to do it.
I have also installed Aptana Studio on my system, now how should I get started with it.
Finally, the last problem is tell me how to check whether rails is currently installed in my system or not...
Thanx in advance!!
to use a gemset try writing
rvm use ruby_gemset_version
to check the rails version try to type rails -v
you have to install RVM (ruby version manager), then you have control to use any specific versions of ruby, and coming to rails you have to manually install rails gem once you have installed rvm and selected a version.
This would be helpful to install rvm
https://rvm.io/rvm/install
After installation you have to install ruby versions.
Then you can use the following cmd
$ rvm use 2.0.0
to use ruby 2.0.0
Thank you.
Go to this http://rvm.io/rvm/install It has instruction to install and cofigure RVM. It is dependant on CURL lib. So make sure you have curl installed in your system, if not then the command is
#sudo apt-get install curl
Once it is intalled and configured properly.
On Ubuntu:
GoTo Terminal > Profile Preferences > Title and Command > Set checkbox for (Run command as login shell)
Install rubies using rvm install.
I recently reinstalled Ubuntu 12.04 after the upgrade package broke my last install. I've been following this walkthrough to restore Rails and continue working on my existing projects. I've already installed rvm, all the packages listed by rvm requirements, and all my development tools (e.g., vim, git, etc.).
However, I get stuck on the rails command, whether I'm trying rails (n,s,g), and returns the error message
$ rails
The program 'rails' is currently not installed. You can install it by typing:
sudo apt-get install rails
I've already done the following:
$ gem install rails
Successfully installed rails-3.2.3
1 gem installed
But based on the following checks, it still hasn't installed.
$ which gem
/home/eyoung/.rvm/bin/gem
$ which ruby
/home/eyoung/.rvm/bin/ruby
$ which rails
(no output)
I'm at my wit's end; any ideas on what's going on?
Extra details:
OS: Ubuntu 12.04 x86_64
Packages: RVM installed Ruby 1.9.3p194 w/ openssl & Rubygems
ruby and gem are on the system $PATH
EDIT: By request,
$ gem list rails
*** LOCAL GEMS ***
rails (3.2.3)
As rails gem was installed and all the other paths look correct, you need to set rvm to use that ruby as your default version. It will set all the paths correctly so you can use your gems and rails command.
rvm use 1.9.3 --default
I updated to 12.04 as well, and ran into the issue as well. After quite a bit of head scratching, I decided to reinstall rvm.
Referencing a previous question.
I am trying to install Ruby, RubyGems, and the Ruby on Rails framework so that it will play nicely with my system. I am having issues with my installation. Could somebody help me? Here are the details of my system and how I went about installation.
Currently I am running ubuntu 10.10 using the Linux Kernel 2.6.35-28-generic. My server is Apache 2.2.16 and I use MySQL 5.1.49.
So, I went to my synaptic package manager and selected the following packages to download:
* ruby1.8 – installs Ruby 1.8.4
* libmysql-ruby – additional libraries to access MySQL
* libruby1.8-dbg – debugging library
* ri – Ruby Interactive Reference
* ruby1.8-dev – header files for building extensions
* rails – Ruby On Rails framework
Once that ran successfully, I downloaded rubygems from http://rubyforge.org/projects/rubygems/. Then I unpacked it, got in the terminal, ran a cd to get in the directory of the newly downloaded rubygems directory, and typed 'sudo ruby setup.rb' That ran with no problem and RubyGems 1.8.5 was installed. Then I ran 'sudo gem install rubygems-update' with no problem.
But when I ran 'sudo gem install rails –include-dependencies' I got the following output:
Fetching: activesupport-3.0.8.gem (100%)
Fetching: rails-3.0.8.gem (100%)
Successfully installed activesupport-3.0.8
Successfully installed rails-3.0.8
2 gems installed
Installing ri documentation for activesupport-3.0.8...
Installing ri documentation for rails-3.0.8...
File not found: lib
ERROR: While generating documentation for rails-3.0.8
... MESSAGE: exit
... RDOC args: --ri --op /var/www/testingwww/rubygems-1.8.5/nclude-dependencies/doc/rails-3.0.8/ri lib --title rails-3.0.8 Documentation --quiet
When I run 'rails -v' I get 'Rails 3.0.8' so it seems to have installed despite the error. But when I try to make a rails app by typing 'rails ./helloWorld' I get the manual page for the rails keyword.
I have looked around for two days now on how to fix this issue, but can't seem to figure it out. Does anybody know how to fix this?
Rails 3 requires version 1.8.7 or 1.9.2.
I'd recommend using RVM to manage your Ruby installation and environments. It will really help to get you going quickly and is simple. It's as simple as
curl -L https://get.rvm.io | bash
to install RVM and then rvm install 1.9.2 will get you going.
Have a look at https://rvm.io for more information.
In addition to Matthew's good Answer, I don't know why you're doing rails ./helloWorld. To generate a new app in Rails 3, you should do rails new helloWorld.
If you need a complete guide to getting rolling with Rails under Ubuntu, you can find a short guide here: http://blog.dcxn.com/2011/06/21/rolling-with-rails-3-on-ubuntu-11-04/
The gist is:
Install RVM (The Ruby version manager)
Install Rails from gem
Get going with Rails
It's a simple process but there are a few things you need to do for it to be completely smooth like making sure you have the pre-requisites for rvm installed via apt before install rvm.
Good luck!
I have been working on installing Rails. However, I am ending up with 2.2.3 and I need 2.3.8.
What I did was I installed ruby via:
apt-get install ruby build-essential #installed 1.8.7
apt-get install rubygems #installed 1.3.6
gem install rails-v2.3.8
I tried to run this but it didn't work. Ubuntu didn't know the command, 'rails' in rails new blog.
I tried to remedy this by installing rails, not via gem but by apt-get:
apt-get install rails
The version installed was rails 2.2.3
What should I be doing to install Rails 2.3.8?
gem install rails -v 2.3.8 should do it. Rails 2 makes a project like "rails name_of_project", without the new keyword. Do a "gem list" to check whether Rails 2.3.8 is installed. If it is, it may be that rails is not in your path.
Edit:
I think that it would work if you add
"export
PATH=/var/lib/gems/1.8/bin:$PATH" to
your ~/.bashrc. I can't really verify
because i work on mac os, but i think
it would. Else, try to execute a "find /
-name "rails" to locate it and add that to your path.
You can install Ruby Version Manager and change version what you want.
