I am configuring a new server for multiple rails 2.x/3.x projects, with multiple ruby versions 1.8.7/1.9.2 using RVM.
I want to know how to set a project to use particular version of ruby and another project to use another version of ruby?
Thanks,
Pravin
Assuming your project directories are:
/var/www/project1
/var/www/project2
Let's move to the multiple rails version management:
Run the below commands:
sudo apt-get update
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties
sudo apt-get install libgdbm-dev libncurses5-dev automake libtool bison libffi-dev
curl -L https://get.rvm.io | bash -s stable
source ~/.rvm/scripts/rvm
echo "source ~/.rvm/scripts/rvm" >> ~/.bashrc
rvm install 1.8.7
rvm use 1.8.7 --default
ruby -v
sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs
gem install rails
rails -v
Now change directory to:
$: var/www/project1 rails s
Move to second project:
$: var/www/project2
rvm install 1.9.1
rvm use 1.9.1 --default
gem install rails
and finally start rails:
$: var/www/project2 rails s -p 3003

My machine has simply capped at ruby version 2.5, ruby -v outputs ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux-gnu]. I have tried sudo apt update && sudo apt upgrade, and sudo apt-get install ruby-full, but non of which have seemed to work.
from: https://phoenixnap.com/kb/how-to-install-ruby-on-ubuntu-18-04
there are other ways, just visit the link to watch some of them
Example 2: By using rbenv
sudo apt install git curl libssl-dev libreadline-dev zlib1g-dev autoconf bison build-essential libyaml-dev libreadline-dev libncurses5-dev libffi-dev libgdbm-dev
sudo apt install rbenv
echo 'export PATH="$HOME/ .rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init –)"' >> ~/.bashrc
rbenv install --list
and from the list select the one you want and install it
ex:
rbenv install rbx-2.7
I have encountered 3 problems while following this guide to installing Metasploit Framework on Ubuntu and Debian:
1) After installing proper version of ruby, there is a command given for installing Ruby libraries: sudo gem install bundler. When I typed that in and hit enter, it says "command not found". After some researching on the internet, I decided to remove sudo and try again. So I've entered gem install bundler and it worked fine. Will this cause any problems?
2) After installing Metasploit Framework, there is a command given to install the required gems and versions:
cd metasploit-framework
bundle install
But when I tried that, I got this error:
rbenv: version '2.1.6' is not installed
I really don't know what to do next (But I moved on).
3) Probably due to the previous problems, in the end when I executed msfconsole command, it said
could not find rake-10.4.2 in any of the sources.
run bundle install to install the missing gems
But the bundle install doesn't help either, because when I run that it says
Could not locate Gemfile or .bundle/directory
Any help would be appreciated.
EDIT: When I asked the person himself who had written the guide, regarding this, he told me to select the version of ruby I had just installed with either rebind or RVM before installing bundler, and then to run the bundle install. Could you please list the commands to do so? I am really new to Linux!
step 1 :
sudo apt-get update
sudo apt-get upgrade
step 2 :
Install dependent packages
sudo apt-get install build-essential libreadline-dev libssl-dev libpq5 libpq-dev libreadline5 libsqlite3-dev libpcap-dev openjdk-7-jre git-core autoconf postgresql pgadmin3 curl zlib1g-dev libxml2-dev libxslt1-dev vncviewer libyaml-dev curl zlib1g-dev
step 3 :
Install Ruby
curl -L https://get.rvm.io | bash -s stable
source ~/.rvm/scripts/rvm
echo "source ~/.rvm/scripts/rvm" >> ~/.bashrc
source ~/.bashrc
rvm install 2.1.6
rvm use 2.1.6 --default
ruby -v
step 4 :
Install and configure postgresql
sudo apt-get install postgresql
sudo -s
su postgres
createuser msf -P -S -R -D
createdb -O msf msf
exit
Step 5 :
Install Metasploit Framework
cd /opt
sudo git clone https://github.com/rapid7/metasploit-framework.git
sudo chown -R `whoami` /opt/metasploit-framework
cd metasploit-framework
cd metasploit-framework
sudo bash -c 'for MSF in $(ls msf*); do ln -s /opt/metasploit-framework/$MSF /usr/local/bin/$MSF;done'
Still if you are facing any issue, you can download the iso or vm image from kali wesbite
I have this problem in kali after install metasploit-framework, and i can't run msfconsole. I solved the problem using the following method:
At change your directory to /usr/share/metasploit-framework:
cd /usr/share/metasploit-framework
and after that, install bundler with gem:
gem install bundler
then:
bundle install
at the end you need to update:
gem update --system
and it will work!
This command fixes it:
apt-get install ruby2.1-dev &&\
apt-get install libsqlite3-dev &&\
bundle install
What it does: install ruby development items
I dont know how to install the latest Ruby on Ubuntu.
First I installed the default Ruby 1.9.3, using
sudo apt-get install ruby
Then I tried to install the 2.0 version using
sudo apt-get install ruby2.0
My version of Ruby is still "ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux])"
What should I do?
There is a PPA with up-to-date versions of Ruby 2.x for Ubuntu 12.04+:
$ sudo apt-add-repository ppa:brightbox/ruby-ng
$ sudo apt-get update
$ sudo apt-get install ruby2.4
$ ruby -v
ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-linux-gnu]
First of all, install the prerequisite libraries:
sudo apt-get update
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev
Then install rbenv, which is used to install Ruby:
cd
git clone https://github.com/rbenv/rbenv.git ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL
git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL
rbenv install 2.3.1
rbenv global 2.3.1
ruby -v
Then (optional) tell Rubygems to not install local documentation:
echo "gem: --no-ri --no-rdoc" > ~/.gemrc

Warning!!!
There are issues with Gnome-Shell. See comment below.
Best is to install it using rvm(ruby version manager).
Run following commands in a terminal:
sudo apt-get update
sudo apt-get install build-essential make curl
\curl -L https://get.rvm.io | bash -s stable
source ~/.bash_profile
rvm install ruby-2.1.4
Then check ruby versions installed and in use:
rvm list
rvm use --default ruby-2.1.4
Also you can directly add ruby bin path to PATH variable. Ruby is installed in
$HOME/.rvm/rubies export PATH=$PATH:$HOME/.rvm/rubies/ruby-2.1.4/bin
Use RVM (Ruby Version Manager) to install and manage any versions of Ruby. You can have multiple versions of Ruby installed on the machine and you can easily select the one you want.
To install RVM type into terminal:
\curl -sSL https://get.rvm.io | bash -s stable
And let it work. After that you will have RVM along with Ruby installed.
Source: RVM Site
update ubuntu:
sudo apt-get update
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev
Install rvm, which manages the ruby versions:
to install rvm use the following command.
\curl -sSL https://get.rvm.io | bash -s stable
source ~/.bash_profile
rvm install ruby-2.1.4
Check ruby versions installed and in use:
rvm list
rvm use --default ruby-2.1.4
I installed RVM on my Fedora 19 system a few months ago, and it was working fine. Then I had some other work and when I opened the machine again, it said:
# rvm
bash: rvm: command not found...
I tried to reinstall RVM, and this is what I get:
# rpm -i rvm-devel-1.17-8.fc19.x86_64.rpm
package rvm-devel-1.17-8.fc19.x86_64 is already installed
But I can't find it.
# ps ax | grep rvm
14363 pts/0 S+ 0:00 grep --color=auto rvm
Can anyone help me? What exactly is the problem?
P.S: The package rvm is there on the system.
# rpm -q rvm
rvm-1.17-8.fc19.x86_64
I recommend you to reinstall RVM, maybe it's crashed due to some event.
Use this command to implode it:
rvm implode
Or:
rm -rf ~/.rvm
Then install it by running:
sudo apt-get install curl
curl -L get.rvm.io | bash -s stable --auto
Then you'll need to reload the ~/.bash_profile file which you can do with this small command:
. ~/.bash_profile
Make sure to install other packages needed for Ruby to work:
sudo apt-get 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 pkg-config
sudo apt-get install pkgconfig
Now install the latest Ruby:
rvm install 2.0.0
rvm use 2.0.0
ruby -v
Now you can install Rails:
gem install rails -v 4.0.0
the package rvm-devel-1.17-8.fc19.x86_64 is not rvm as per http://rpm.pbone.net/index.php3/stat/4/idpl/20537074/dir/fedora_19/com/rvm-devel-1.17-8.fc19.x86_64.rpm.html it is:
The rvm-devel package contains libraries and header files for
developing applications that use rvm.
Follow installation instructions http://rvm.io/rvm/install to get RVM installed, make sure to read the outputs as important hints might be printed for you.
to uninstall rvm use anyone of the following:
rvm implode
or
rm -rf ~/.rvm
Just to be sure restart the terminal before you try installing rvm again
I have successfully installed rvm, but when I run the following commands
sudo apt-get update
Or:
rvm install 2.0.0
I have the following errors:
W: Failed to fetch http://ppa.launchpad.net/cheleb/blender-svn/ubuntu/dists/precise/main/source/Sources 404 Not Found

W: Failed to fetch http://ppa.launchpad.net/ferramroberto/oneiric/ubuntu/dists/precise/main/binary-i386/Packages 404 Not Found
How can I fix these errors?
follow below steps
sudo apt-get -y update
sudo apt-get -y install build-essential zlib1g-dev libssl-dev libreadline6-dev libyaml-dev
cd /tmp
wget http://cache.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p481.tar.gz
tar -xvzf ruby-2.0.0-p481.tar.gz
cd ruby-2.0.0-p481/
./configure --prefix=/usr/local
make
sudo make install
Use rvm to install stable ruby:
curl -sSL https://get.rvm.io | bash -s stable --ruby
or, if you have rvm already, get stable version:
rvm get stable
Install ruby and use the specific version of ruby (remember to use login shell)
/bin/bash --login
rvm install 2.0.0
rvm use 2.0.0
rvm rubygems latest
ruby --version
As found on the official RVM website.
EDIT:
As #prem points out run this at first and follow the above steps if there is a public key error

Use rbenv to install ruby:
Install necessary dependancies:
sudo apt-get update && sudo apt-get install git-core curl zlib1g-dev \
build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev \
sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev \
python-software-properties libffi-dev
Install rbenv:
cd
git clone git://github.com/sstephenson/rbenv.git .rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bash_profile
source ~/.bash_profile
Install ruby:
rbenv install -v 2.0.0
From the travis-cli installation instructions for Ubuntu, the Brightbox Ruby NG(NextGeneration) ppa:
$ sudo apt-get install python-software-properties
$ sudo apt-add-repository ppa:brightbox/ruby-ng
$ sudo apt-get update
$ sudo apt-get install ruby2.1 ruby-switch
$ sudo ruby-switch --set ruby2.1
Although this answer was accepted, I would strongly recommend using rvm rather. I had nothing but trouble trying to install ruby without it. See e.g. this guide:
https://www.digitalocean.com/community/articles/how-to-install-ruby-on-rails-on-ubuntu-12-04-lts-precise-pangolin-with-rvm
Any easy way to install ruby is with ruby-install. I had compile errors when building ruby from scratch, but ruby-install encountered no such problems.
edit: I've had problems with rvm in the past, and feel I should actively recommend against this. That's just me personally, though. I've had okay luck with rbenv, but always use it in conjunction with ruby-install.
You have some ppa sources enabled that aren't available for your version of Ubuntu. Comment those out in your /etc/apt/sources.list , run sudo apt-get update , and you'll be fine.
Use rbenv
The first step is to install some dependencies for Ruby.
sudo apt-get update
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties
Installing with rbenv is a simple two step process. First you install rbenv, and then ruby-build:
cd
git clone git://github.com/sstephenson/rbenv.git .rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL
git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL
rbenv install 2.0.0
rbenv global 2.0.0
ruby -v

I put #PravinMishra's source into a Gist and now you can simply use this one liner:
wget -O - https://git.io/vvkI4 | bash
NOTE: Don't trust my Gist blindly, download the file and look into it before you run it!
