How can I update Ruby version 2.0.0 to the latest version in Mac OS X v10.10 (Yosemite)?
ruby, version
Solution
Open your terminal and run
curl -sSL https://raw.githubusercontent.com/rvm/rvm/master/binscripts/rvm-installer | bash -s stable
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`.
Prerequisites for Windows 10:
- C compiler. You can use http://www.mingw.org/
- `make` command available otherwise it will complain that "bash: make: command not found". You can install it by running `mingw-get install msys-make`
- Add "C:\MinGW\msys\1.0\bin" and "C:\MinGW\bin" to your path environment variable

I need to update my Ruby version from 2.0.0 to the latest version. I can not use some gems because my version is not updated. I had used Homebrew to install Ruby some time ago. How can I update my Ruby version?
