How to update ruby in windows

The easiest way for you might be to use RubyInstaller, which its version 2.0.0-p0 is now available for download as installers. Follow the link http://rubyinstaller.org/ for more information.

How to update Ruby 2.2.4 to 2.2..5

Because you used Rails Installer to get Ruby set up initially, you will need to download an updated version of RailsInstaller. Unfortunately, it's current 2.2 installer includes 2.2.4.

One suggestion would be to remove RailsInstaller and use RubyInstaller instead. Unfortunately, then you would also need to set up other tools, such as Git, a database, etc.

The other thing you could try is going to an older version of ruby_dep, it appears that 1.3.1 would be suitable for you. This is dependent upon the rest of your project, since it's possible you need the current version of ruby_dep.

How to update Ruby Version 2.0.0 to the latest version in Mac OSX Yosemite?

When this is complete, you need to restart your terminal for the rvm command to work.

Now, run rvm list known

This shows the list of versions of the ruby.

Now, run rvm install ruby@latest to get the latest ruby version.

How to install ruby 2.4.0 in Windows 10

Windows 10 comes with a new feature called Windows Subsystem for Linux (WSL) that allows you to use Bash with the most common Linux tools included the ones you need to install a Ruby Manager Version.

For this tutorial we'll set up Ubuntu on Windows, Ruby 2.4.0, Rails 5.0.1 and PostgreSQL.

Installing Bash On Windows

First enable developer mode on your machine
https://www.youtube.com/watch?v=S6NvjvL3xaI
Next install Windows Subsystem for Linux
https://www.youtube.com/watch?v=g_5hxfFKDL8
And restart your computer.
After the computer reboot open a Command Prompt (CMD) and type
```
> bash
```

You will see the next message

This will install Ubuntu on Windows, distributed by Canonical
and licensed under its terms available here:
https://aka.ms/uowterms
Press "y" to continue: y

Press "Y" to continue

Downloading from the Windows Store... 100%
Extracting filesystem, this will take a few minutes….

Bash will ask you for a user, please remember this user because bash will ask you every time you need root permissions in Bash. Also when you time your password you won’t see the keystrokes, it’s normal, only keep typing and press ENTER when you finish.
```
Please create a default UNIX user account. The username does not need to match your Windows username.
For more information visit: https://aka.ms.wslusers
Enter new UNIX username:
Enter new UNIX password:
```
And your Bash is ready when you see the CMD its in the
mnt/c/Users/your_username directory.

your_username@yourmachine:/mnt/c/Users/your_username$

Installing RVM and Ruby

In your bash copy this line:

$ gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB

Then install gnup2
```
$ sudo apt-get install gnupg2
```

Remember your UNIX password because every time you saw a sudo in the command you will be asked for your password.

Install RVM
$ \curl -sSL https://get.rvm.io -o rvm.sh

$ cat rvm.sh | bash -s stable

$ source ~/.rvm/scripts/rvm

Install Ruby
```
$ rvm install ruby-2.4.0
```

If you need to install other version of ruby run this same command like this

$ rvm install ruby-2.3.5

And select the ruby version you want to use

$ rvm --default use 2.3.5

To check if it works

$ ruby -v

Installing RubyOnRails

Install the Ruby’s package manager Bundler
```
$ gem install bundler 
```

Add NodeJS

$ curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -

$ sudo apt-get install -y nodejs

Install Rails
```
$ gem install rails
```

Installing PostgreSQL

Download PostgreSQL installer and follow the instructions of the installation
https://www.openscg.com/bigsql/postgresql/installers.jsp/
The installer will ask you for a user and a password, also keep them in a safe place because you will use it to access to PostgreSQL command line and in database.ymlin your ROR project.
When the installation finish, return to bash and type the next command
```
$psql -p 5432 -h localhost -U your_postgresql_username
```

Bash will ask you the PostgreSQL password and if everything works you will have access to the Postgres shell prompt

psql (9.5.6, server 9.6.2)
WARNING: psql major version 9.5, server major version 9.6.
Some psql features might not work.
Type "help" for help.
postgres=#

Type \q to exit the Postgres shell.

Running your Rails app

Open the project in your favorite editor and update the database.yml with the PostgreSQL username and password.

development:
  database: your_app_name_development
  username: your_postgres_user
  password: your_postgres_password
  host: localhost
  port: 5432

test:
  database: your_app_name_test
  username: your_postgres_user
  password: your_postgres_password
  host: localhost
  port: 5432

In Bash go to the directory where is your rails project, for example:
```
$ cd Projects/my_app
```

To learn more about Bash navigation visit
https://www.pluralsight.com/guides/beginner-linux-navigation-manual

Create your database
```
$ rake db:create
```
Run the rails server to make sure everything is working
```
$ rails s
```
And go to your browser and visit
```
$ localhost:3000
```

Every time you need a Bash, open a Command Prompt and type

>bash -l

Why is Ruby not updating after updating with Ruby Installer?

You need to update your PATH environment variable, it is still pointing to the old installation. If I remember correctly, the installer does have a box to check off to set the PATH variable. Only one installation at a time can be in your PATH.

See this answer for a quick way to change the variable. It will follow the same syntax as the following.

Open cmd.exe and type:

set PATH=%PATH%;C:\Ruby250\bin

Your installation location may be different, confirm before entering. You can also do it through the properties window of MyComputer or whatever they call it now. I find the terminal to be simpler, as it take abouts 6 windows deep to change through the GUI.

Step By Step:

Find the directory where ruby is installed to, usually
C:\Ruby250\bin (version may vary)
Open a command prompt, terminal, cmd.exe, or whatever name you
prefer to call it.
Type set PATH=%PATH%;C:\Ruby250\bin (change folder name if yours
is different)
Press Enter button
In a new cmd.exe, type ruby -v
Enjoy

ANOTHER EDIT

Click on the "Start" button (probably bottom-left of your screen)
Start typing the word "environment" until you see the option Edit the system environment variables appear
Click on that
A small window will open, towards the bottom left is a button that
reads Environment Variables
Click on that button
There will be two sections, one for the user (that is current account
only) and the other is the "system", which is the default and
system-wide variables
In each of these (just to be sure), highlight the line that has
"Path" for the name of the variable
Find the button under the list that you just clicked in that reads
Edit...
Click on it
Look through list, it is different for everyone, can't read it for
you. Find the one that it is the location of a Ruby installation,
mine reads C:\Ruby24\bin because I am using Ruby 2.4.4
YOU NEED TO MAKE SURE THAT THE FOLDER PATH IS WHERE YOU INSTALLED
RUBY. This cannot be done for you, only you know. It is by default
C:\RUBY***\bin, where the *** is your version number. You have to
open explorer and simply look.
If the variable is where is where Ruby 2.5 is installed, good, it
doesn't need changed, but look through the list to make sure there
are no other paths to other versions of Ruby. If there are, highlight
them and click the delete the button to remove.
Click OK on each window that you may have made an edit, not
Cancel, and not X out the window.
To confirm it works, open a new command window, if one was already
open, the changes will not be updated in it.
