Jason Frey commented on PROTON-1660:
------------------------------------
FYI, on my system where I have json_pure also installed, I am seeing the
following error:
```
Fetching: json-0.4.3.gem (100%)
json's executable "edit_json.rb" conflicts with json_pure
Overwrite the executable? [yN] n
ERROR: Error installing qpid_proton:
"edit_json.rb" from json conflicts with installed executable from
json_pure
```
But that's because it resolves to 0.4.3 instead of the latest 2.1.0
> The gemspec dependency on "json ~> 0" breaks anyone dependning on a recent
> version of json

> https://github.com/apache/qpid-proton/blob/0790bb99fabc4a6d7c1c12fb09c0ff76a3594f5a/proton-c/bindings/ruby/qpid_proton.gemspec.in#L31

> This line was recently changed in qpid-proton master. It causes any project
> that depends on a recent version of json to break when pulling together
> dependencies. The pessimistic style of version constraint means that
> qpid-proton requires a json version of >= 0.0, but < 1.
> For instance, our project has a dependency on json 2.x. And, we see this
> error when bundling with qpid-proton:
> {code:none}
> Bundler could not find compatible versions for gem "json":
> In Gemfile: manageiq-providers-azure was resolved to 0.1.0,
> which depends on azure-armrest (~> 0.9.1) was resolved to 0.9.1, which
> depends on json (~> 2.0.1)
> qpid_proton (~> 0.18) was resolved to 0.18.0, which depends on json (~> 0)
> {code}
