rdoc and json are incompatible
isuruf opened this issue · 8 comments
rdoc needs json ~> 1.4 (>=1.4, < 2.0) and nmatrix requires >= 2.0.1.
I believe I just put in ~> 2.0.1 because that's the one I got working at the time. Do you want to see what happens in your PR if you change it to 1.4?
I just did, and it fails to install json 1.8.3. json needs to be updated to 2.0.1 to build with the latest ruby version. So, I guess this is an issue with rdoc
Problem is that with ruby 2.4.0-dev, this is checked strictly. Earlier when ruby 2.0.1 was installed it was okay even if rdoc needed < 2.0. Now it is enforced and therefore fails.
Is this the problem?
It looks like we can just drop the json requirement altogether, yes?
Yes, it is. Dropping the json requirement won't help, since rdoc has json as a requirement.
Dropping the requirement will help ruby versions < 2.4
Looks like we need RDoc 5.
Possibly related to #606?
