Ruby on Rails Wednesday, January 11, 2017

Hi Cai,

Its advisable to use a version manager to manage ruby and gem versions. You can refer to - it has nice documentation and allows you to install specific versions of ruby that you are interested in.

I myself use MacBook Pro and never had issues with rvm.

So I am trying to download Ruby from this site ---

Managed to download Mac OSX 10.7 and 10.8 , but when I tried to open it, this is the message I got : 

"RailsInstaller-1.0.4-osx-10.7" can't be opened because it is from an unidentified developer. 

Your security preferences allow installation of only apps from the Mac App Store and identified developers. 

Safari downloaded this file today at 10:34 pm 

Any idea how to fix this ?
