Installed Ruby Using Apt-Get Install Ruby 2.0.0 Succeeded But Not Using Correct Ruby Version

installed ruby using apt-get install ruby 2.0.0 succeeded but not using correct ruby version

If you're new to linux I'd recommend using something like RVM (Ruby Version Manager) to install ruby. It makes it easier to switch ruby versions and manage multiple gemsets.

To install RVM with the latest (stable) ruby:

\curl -L https://get.rvm.io | bash -s stable --ruby

then check which rubies are installed by using

rvm list

you can then switch ruby versions using

rvm use 2.0.0 --default

with the --default flag overriding any system ruby.

Update

If you really don't want to use RVM, then use

sudo apt-get install checkinstall

wget -c http://ftp.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p0.tar.gz
tar -xzf ruby-2.0.0-p0.tar.gz
cd ruby-2.0.0-p0

./configure   
make

sudo checkinstall -y \
  --pkgversion 2.0.0-p0 \
  --provides "ruby-interpreter"

checkinstall will package the source, making it easier to remove in the future

You'll then need to add the Ruby binaries to your path, by editing the env file:

sudo nano /etc/environment

add /usr/local/ruby/bin

PATH="/usr/local/ruby/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

then run

source /etc/environment

to reload the file, and check your ruby version with

ruby -v

How to fix Your Ruby version is 2.3.0, but your Gemfile specified 2.2.5 while server starting

You better install Ruby 2.2.5 for compatibility. The Ruby version in your local machine is different from the one declared in Gemfile.

If you're using rvm:

rvm install 2.2.5
rvm use 2.2.5

else if you're using rbenv:

rbenv install 2.2.5
rbenv local 2.2.5

else if you can not change ruby version by rbenv,

You need to update the Ruby version, you are using an old version of Ruby.

An error occurred while installing ruby-2.0.0

Ruby 2.0.0 is very old, and not supported on Heroku anymore. You need to upgrade to a more recent version.

You can see all the supported ruby versions here: https://devcenter.heroku.com/articles/ruby-support#supported-runtimes

How to change versions of Ruby 1.9 to Ruby 2.0 in the new Windows 10 Bash shell?

Currently, WSL is based on Ubuntu 14.04, so there are no recent Ruby versions available with the official apt repos.

You can install Ruby 2.1, 2.2 and 2.3 via Brightbox/ruby-ng ppa repository if you prefer managing packages with apt.

Quoting from the Brightbox site:

$ sudo apt-get install software-properties-common
$ sudo apt-add-repository ppa:brightbox/ruby-ng
$ sudo apt-get update

And then,

sudo apt-get install ruby2.1

Otherwise, rbenv is an another option to achieve that.

bundle install doesn't succeed

I found the reason of this failure, which was the compatibility of the versions of those gems and ruby version.

I very much knew that could be a problem, but I thought I made sure I set the proper ruby version for the gems versions specified in the Gemfile/Gemfile.lock. What I did miss was the trace of misconfigure of rbenv, which is shown as '2.3.0' in the log. What I thought it should have been was '2.0.0'.

Since I didn't do good rbenv setup, bundler was referring to the ruby not in the project directory. Hence obvious version incompatibilities.
