Build fails due to incompatible versions of "childprocess"

[dvanbrug]

Building fails with the following error.

Bundler could not find compatible versions for gem "childprocess":
In Gemfile:
vagrant was resolved to 2.2.4, which depends on
childprocess (~> 0.6.0)

vagrant-spec was resolved to 0.0.1, which depends on
  childprocess (~> 3.0.0)

It looks like vagrant-spec recently updated to childprocess 3.0.0 (April 2, 2020, ab145fa).

I've worked around this locally by updating my Gemfile on line 30 to look like this:

gem 'vagrant-spec', git: "https://github.com/hashicorp/vagrant-spec.git", :ref => '161128'

The latest version of vagrant master branch has been updated to the same dependency but it does not look like they've released a tagged release with the update yet.

Yeah, vagrant-spec has no gem or tagged releases so it's a bit of a tricky situation, but tests are generally easier with it than without it, as they cover use-cases I'm not usually thinking of (like chef provisioning).

I think it's fair to just leave it at the ref for now, it's only a dev dep anyway.
