Well I am having a really weird problem, I am working on a project of  
another team and they were using ruby 1.8.7. I has installed ruby  
1.8.6 so I’ve got many ruby errors and I couldn’t figures out why.

Finally I found that the reason was the version of the ruby, I have  
installed RVM and I set 1.8.7 version as default and I ran the app but  
I am still getting those errors.

Can I explicitly setup the ruby version which I want my rails app to  
use? My final solution is to delete ruby 1.8.6 version…

Just for the record, one of the errors I got was that:  
select\_tag “hour”, options\_for\_select(24.times.collect {|i| i}

and here I found the answer:

> **[Elctech.com is for sale | HugeDomains](https://www.hugedomains.com/domain_profile.cfm?d=elctech.com)**
>
> Get a new domain name for your startup. Quick and professional service. Seamless domain transfers.

I have many more errors which I assume that it might be the ruby  
version because the app is live and running smoothly.

Thank you

Well the problem was that I ran the command as a root (sudo script/  
server) so the ruby 1.8.6 was used. When I am running for the version  
1.8.7 I am getting the following errors:

Any ideas what it might been wrong?

Thank you for your answer but can you be a little more specific? I  
have ubuntu and I have already installed openssl libraries but it  
doesn’t work. I found some guides which says to go at \gems\ruby-1.8.7-  
p249\ext\openssl but I didn’t have the folder /ext/openssl/ .

Install your missing ruby openssl libraries.
