Question

Now on my localhost I’m starting developing first simple web service using ruby 1.9.2 and rails 3.2.1 versions . But my hoster support only 2.3.14 version of ruby (becouse he is using Cpanel). Will a have problem with this? how to prevent them? Moreover, what difference is between 3.2.1 and 2.3.14, I meen gems etc? O it is better to start now developing using 2.3.14? what gems would not work in 2.3.14? will haml, sass, captcha and other gems work in old version?

Answer 1

Given you must use this host, I would suggest setting up your development environment to match. A nice way to manage having multiple versions of ruby and try different gems is to use rvm. This will allow you to manage multiple combinations of ruby (1.8.7, 1.9.2, ect) and multiple versions of rails and other associated gems.

As for the specific gems, both haml and sass will work with rails 2.3.
I am not sure what captcha gem you wish to use but from the popular recaptcha gem readme:

“Rails apps below 3.0 are no longer supported, but you can install an older release and view it’s README.”

All in all you can make this setup work and you should not disrepair. There is a TON of example code out there on how to write and manage rails 2.3.
Good luck
