[gentoo-user] Strange problem with Ruby (vagrant)

[Alexey Eschenko]

Hi.

I need to use Vagrant but it doesn't work with strange error message:

I'm calling it's strange because I have rubyzip package in my system (as
said in error message).

I've decided that it's typical dependency problem and installed
rubyzip-1.2.2. Then I've got new error:

> $ vagrant
> Traceback (most recent call last):
> <removed>
> /usr/lib64/ruby/site_ruby/2.6.0/rubygems/specification.rb:2298:in
> `raise_if_conflicts': Unable to activate vagrant_cloud-2.0.3, because

> (Gem::ConflictError)
> <removed>

Then I've checked which packages require rest-client and got these:

> $ equery d rest-client
>  * These packages depend on rest-client:
> app-emulation/vagrant-2.2.6 (ruby_targets_ruby24 ?
> dev-ruby/rest-client:2[ruby_targets_ruby24])

>                              (ruby_targets_ruby26 ?
> >=dev-ruby/rest-client-2.0.2[ruby_targets_ruby26])

So I've removed rest-client-2.1.0 and installed 2.0.2. And then:

So I want to ask if someone at all have working Vagrant installation on
~amd64 or it's just broken?
