[Rock-dev] Growing list of ruby gems - autorespawn?

[Steffen Planthaber]

Hi,

Mostly, these errors occur when gems are updated on rubygems.org.

The last gem affected was "activesupport", the issue is explained in the PR:
https://github.com/rock-core/package_set/pull/71

"autorespawn", indeed requires ruby 2.1
https://rubygems.org/gems/autorespawn

Normally, to solve the issue, you could install the autorespawn gem 
manually in the correct version BEFORE you do the autoproj  update.
But all versions of autorespawn require ruby 2.1 :-(

so
$> gem install autorespawn -v 0.4.1
won't work.

$> autoproj show autorespawn
tells that the only package that requires it is "tools/roby", where it 
is listed as optional, so you can remove the line from 
tools/roby/manifest.xml as a quick fix.


Best, Steffen
