Strange skipping of dependencies when python requirement is specified ("Not needed for the current environment") #2187
Description
- 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 (
-vvvoption).

Issue
When I run poetry install I expect all packages to be installed when running python 3.6.8, that doesn't seem to happen and I get the following output. It does work if I remove the python requirement on the dependency.
While this configuration doesn't make much sense in this case, consider the case where multiple python versions need to be supported (ie in my case I'm making the last release for python 2.7 for a package and thus, need to support multiple python versions at least for one more release.
I also know that this bug isn't isolated to seed-isort-config, I tried a few other packages just to be safe and found it produces the same result for flake8, etc... So it seems to be a poetry issue.
$ poetry install -vvv
