Can't install vagrant-disksize on fedora 30 with Vagrant 2.2.4 and rubygem-rdoc-6.1.0

[Guigzai]

Hi,

I use fedora 30 :

• Vagrant 2.2.4
• rubygem-rdoc-6.1.0-120.fc30.noarch

When I try to install plugin, an error occur : vagrant plugin install vagrant-disksize Installing the 'vagrant-disksize' plugin. This can take a few minutes... /usr/share/gems/gems/psych-3.1.0/lib/psych.rb:237: warning: already initialized constant Psych::LIBYAML_VERSION /usr/share/ruby/psych.rb:237: warning: previous definition of LIBYAML_VERSION was here /usr/share/gems/gems/psych-3.1.0/lib/psych.rb:239: warning: already initialized constant Psych::NOT_GIVEN /usr/share/ruby/psych.rb:239: warning: previous definition of NOT_GIVEN was here Fetching micromachine-3.0.0.gem Fetching vagrant-vbguest-0.19.0.gem Parsing documentation for dotenv-deployment-0.0.2 Parsing documentation for dotenv-0.11.1 Parsing documentation for vagrant-env-0.0.3 Parsing documentation for vagrant-newdisk-0.0.3 Parsing documentation for vagrant-persistent-storage-0.0.47 Parsing documentation for vagrant-proxyconf-2.0.1 Parsing documentation for vagrant-reload-0.0.1 Parsing documentation for micromachine-3.0.0 Installing ri documentation for micromachine-3.0.0 Parsing documentation for vagrant-vbguest-0.19.0 Installing ri documentation for vagrant-vbguest-0.19.0 Parsing documentation for vagrant-disksize-0.1.3 Before reporting this, could you check that the file you're documenting has proper syntax:

/usr/bin/ruby -c lib/vagrant/disksize.rb

RDoc is not a full Ruby parser and will fail when fed invalid ruby programs.

The internal error was:

I was able to workaround this by uninstalling the Fedora vagrant packages running Hashicorp's vagrant binary. It's not a Fedora problem, btw. Seems there were some vagrant plugins built against old dependencies.

I have also run into this.

As a temporary workaround, just do dnf remove rubygem-rdoc to get it working.
