Having rails compatibility issues on my system. how do i wipe rails and start over?

Question

I have rails 3.2.6 on my kubuntu system (13.04). I had rails 3.2.6 and rails 4.0.0 on my system. I uninstalled rails 4.0.0 and then ran into all kinds of issues with rails not working right since then (my job only uses rails 3.2.X).

When I do a gem list, it says rails (3.2.6). However, when I do a rails -v it reports rails 4.0.0.

How can I completely wipe rails and start over fresh??

thanks!!

This might not be the best way, but it could get you close to removing rails 4.

If it rails 4 was installed by apt, you could get apt to remove it.

First comfirm rails 4 was installed by the package manager:

Run which rails and see where the rails command lives. Then run dpkg -L rails which will list all the files installed with apt for the package rails.

You could of course do this in one line

dpkg -L rails | grep `which rails`

Then if your result from which matches, then remove this using apt.

apt-get --purge remove rails

Hope this helps,
