How can I update Ruby version 2.0.0 to the latest version in Mac OS X v10.10 (Yosemite)?

Use

sudo gem update --system

And simply restart the PC.

Use:

`brew install rbenv ruby-build`

Add *rbenv* to Bash so that it loads every time you open a terminal:

`echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile`

`source ~/.bash_profile`

#### Install Ruby

`rbenv install 2.6.5`

`rbenv global 2.6.5`

`ruby -v`

The simplest way is definitely to enter the following command in the terminal:

```lang-none
sudo gem update --system
```

You can add the flag `--no-document` if you do not want to download the documentation. Here is sample output after running the command:

```lang-none
sudo gem update --system

RubyGems installed the following executables:

Ruby Interactive (ri) documentation was installed. ri is kind of like man
pages for ruby libraries. You may access it like this:
ri Classname
ri Classname.class_method
ri Classname#instance_method

```

For the `rvm` command to work, you need to run:

source ~/.rvm/scripts/rvm

Now, run `rvm list known`

This shows the list of versions of the Ruby interpreter.

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

If you type `ruby -v` in the terminal, you should see `ruby X.X.X`.

If it still shows you `ruby 2.0.`, run `rvm use ruby-X.X.X --default`.
