This question seems to imply OS X/macOS comes with the ruby framework rails. Is this correct? (I always thought OS X/macOS comes with ruby, but not rails)
No, macOS does not come with
On a default clean install of macOS Catalinia, if you run the following command in Terminal, you'll see that
rails is not installed by default.
% rails -v Rails is not currently installed on this system. To get the latest version, simply type: $ sudo gem install rails You can then rerun your "rails" command. %
I also tested this on some earlier versions of macOS and the result was the same.
rails -v returns version info, then it's installed, but was done after macOS was originally installed.
