Re: Bug#734156: how-can-i-help: "no such file to load -- debian_version" after upgrade of ruby-debian package
@ Armin: you install to 'apt-get install ruby'
Hi Debian-Ruby,
The bug report below is interesting. The user has ruby1.8 installed, that
provides ruby-interpreter. As a result, h-c-i-h Depends' line is satisfied:
Depends: ruby | ruby-interpreter, ruby-debian, ruby-json
However, since ruby-debian no longer has support for ruby1.8, h-c-i-h can't use
ruby1.8.
I'm not sure of how to address this situation. For now, I'll just drop
|ruby-interpreter. But the overall handling of dependencies when switching Ruby
versions seems fragile. And there are 578 occurences of "Depends: ruby
| ruby-interpreter" in the archive, which scares me a bit.
Maybe ruby-defaults should provide a symlink to the default ruby version
that we could use in shebangs (#!/usr/bin/ruby-debian-default)? That
would allow to ensure that hcih really runs with ruby1.9.3 even if the
user used update-alternatives to switch to another version.
