Installation fails due to conflicting wheel version

[NeolithEra]

Hi, users are unable to run ops due to dependency conflict with wheel package. As shown in the following full dependency graph of ops, billiard==3.5.0.4 requires wheel>=0.29.0，while django-crispy-forms==1.7.2 requires wheel==0.24.0.

According to pip’s “first found wins” installation strategy, wheel==0.33.4 is the actually installed version. However, wheel==0.33.4 does not satisfy wheel==0.24.0.

Solution

1. Fix your direct dependency to be wheel==0.24.0. I have checked this revision will not affect your downstream projects now.

2. Ask your upstream project django-crispy-forms to loose the version range of wheel.

Which solution do you prefer, 1 or 2?
@pythonzm Please let me know your choice. I can submit a PR to solve this issue.
