as far as i can tell 2 is greater than 1.7, as per the requirement listed in your output, im not sure where the 1.11 and 1.8 are from and without you providing more detail, there is nothing we can do to help you

[pradyunsg]

Hi @itJunky!

[exec] Collecting django==1.11
[exec] Collecting django>=1.7 (from django-notifications-hq)

This looks like another case of #988 to me.

[itJunky]

I think it goes because in ant build.xml i download all wheels before installation. And when resolve depends for django-notifications-hq i doesn't have django-1.11 installed.

[chrahunt]

One approach would be to explicitly define (in the initial wheel download) the versions that you want and then pass --no-index to pip install.

I hope that helps. Since this looks like something that will be resolved by #988 I will close this issue, but please let us know if you have any other trouble.
