Hi:) I have manually set Ruby 1.9.1. I have installed it via

./configure --prefix=/opt
make
make install

The target uninstall does not exist in generated Makefile ...
How to do uninstallation correctly?

PS: I also believe that it is necessary to remove all the gems.
For this I use

#!/bin/sh
gem list --local | grep [^*] | cut -d     -f 1 | xargs gem uninstall

Answer 1

I had a similar problem with another software installed in /opt. I solved the issue by

creating an empty directory elsewhere (like /tmp/ruby)
installing exactly the same version you want to remove in this directory
printing a list of all files in the new location, replacing/tmp/ruby with /opt.
erasing the resulting list

On unix, you can first try:

$ find /tmp/ruby | sed "s//tmp/ruby///opt//"

Look carefully at the list, if it seems valid, use:

$ find /tmp/ruby | sed "s//tmp/ruby///opt//" | xargs rm

To really remove the files...
