I just downloaded Ruby 2.0.0 using RubyInstaller, but Ruby -v still says I'm running 1.9.3. What am I doing wrong?

Question

I just downloaded Ruby 2.0.0 using RubyInstaller, but Ruby -v still says I'm running 1.9.3. What am I doing wrong?

I am running Windows 7 (which I know is not ideal, but is what I'm currently stuck with), and I have successfully run Ruby in the past.

Thanks!

Answer 1

I did a combination of several answers here, including:

• Uninstalling old versions of Ruby and reinstalling version 2.0.0
• Update the path Environment variable to the new path
• Restart the computer (I think this is what I was missing the whole time)

Thanks to everyone who helped!

Answer 2

first uninstall all your rubies and then install ruby 2.0, you cannot maintain two versions of ruby without RVM or RBENV.

Answer 3

Checkout the PATH environment variable. Most likely it contains path to ruby1.9.3/bin. Change it to point to ruby2.0/bin
