Dependency problem when installing dynamic-rest 1.8.0 with django 2.0.7

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Linux Mint 19 Tara
• Poetry version: Poetry 0.12.10
• Link of a Gist with the contents of your pyproject.toml file: https://gist.github.com/gonvaled/914f5fda1b55c22a161741b566e7a555

Issue

I am not sure what is going on, since dynamic-rest 1.8.0 is supposed to be compatible with django 2.0.7:

» poetry add dynamic-rest==1.8.0

[SolverProblemError]                                                  
Because dynamic-rest (1.8.0) depends on Django (>=1.8,<2.0)                        
 and poetry-demo depends on Django (^2.0.7), dynamic-rest is forbidden.            
So, because poetry-demo depends on dynamic-rest (=1.8.0), version solving failed.

I am on python 3.6.5:

» python --version
Python 3.6.5

According to dynamic-rest sources, these are the requirements for python 3:

Django>=1.8,<2.1
djangorestframework>=3.1.0,<3.8
inflection==0.3.1
requests

[gonvaled]

according to this, version 1.8 does not support django 2.0

Yes, and afaik, that is used for python 2 (https://github.com/AltSchool/dynamic-rest/blob/master/setup.py):

    install_requires=open('install_requires.txt'
                          if sys.version_info.major == 2
                          else 'install_requires_python3.txt').readlines(),

The relevant file for python 3 should be the one I linked above, which has:

Django>=1.8,<2.1
djangorestframework>=3.1.0,<3.8
inflection==0.3.1
requests

So, in theory this is compatible with Django 2.0 when using python3.

No idea what is going on.

@sdispater: could it be that poetry is making assumptions and using install_requires.txt if it exists, instead of relying on the execution of setup.py?

I have a related issue open in the other project: https://github.com/AltSchool/dynamic-rest/issues/264
