Issue
When installing a package with an integer at the end of the package name, the solver is not finding the correct package. The specific package I am having trouble with is flask-restful-swagger-2. latest at the time of writing is 0.35
adding unbounded:
$ poetry add flask-restful-swagger-2
Using version ^0.20 for flask-restful-swagger-2
