Unit tests do not run locally

[modohash]

When trying to run the unit tests for the project locally, no matter how many versions I go back, they always fail with the error:

`An error occurred while loading spec_helper.
Failure/Error: require 'webmock/rspec'

NameError:
uninitialized constant CookieJar::CookieValidation::PATTERN::IPV4ADDR

`

Looking at the automated build for the project it also fails with the same error. Is there some other way to run the tests locally or some fix that can be applied? Not having the unit tests running seems like it would inhibit contributions.

Any help would be appreciated.

This is from this issue: ruby/uri#131

A workaround is to limit the uri gem version in your app.
E.g. in a Gemfile:

gem "uri", "~> 0.13"
