My rails application does not start, it displays a 404 error. The application log (public_html/user/log/production.log) contains:

"MissingSourceFile (no such file to load -- postgres)"

The error message in the log file contains:
MissingSourcefile (no such file to load)

I installed Ruby Gems via whm > apache update and Ruby Rails manually. What else am I to do to get this working? Postgres was compiled as well and has always been installed.


root@server [~]# which postgres
/usr/bin/postgres



root@server [~]# php -m

It's probably referring to the Ruby gem named "postgres" and not just the database. It's case sensitive as well. Now, go read up on Ruby, it'll probably do you good if you're going to deal with Ruby on Rails web applications.

This should list the gems installed:

And listing your PHP modules is kind of pointless, PHP has nothing to do with Ruby.

Sure pointless, but I listed it to show that postgres was installed, so not so pointless after all.

root@server [~]# gem list | egrep -v "^( |$)"

I don't see postgres in that gem list, so that's most likely the problem. Install the postgres gem and you should be golden. And it's not referring to the database. And it is pointless to list PHP modules when you're dealing with Ruby, again, Ruby is not PHP, they have nothing in common but being a programming language.

Thanks, I installed it. I appreciate your kind help

Ok, still not working after installing postgres module via whm > Module Installers.

However, see screenshot of whm where I installed the module. It shows up there, but not in command line.

Still getting this in error logs

"no such file to load -- postgres"

And page shows 404.

How did you install it? I'd say, trust the command line, not the GUI.

I installed Ruby Gems via command line (cpanel script) and ruby postgres gem via whm interface

Don't trust the cpanel script, install it manually as it might have put it in another location perhaps.
