`pip wheel` 命令可以创建*通用* 轮子吗？

Question

Is there a way to use the pip wheel command to create universal wheels?

For instance, taking aws_requests_auth as an example, if I execute
pip wheel aws_requests_auth, a Python3 wheel is created: aws_requests_auth-0.4.1-py3-none-any.whl .

Can I change something to create a py2.py3-none-any.whl wheel?

Files used in the above example:

$ ls -R
.:
aws_requests_auth  CHANGELOG.md  dist  LICENSE  MANIFEST  MANIFEST.in  PKG-INFO  README.md  setup.py

./aws_requests_auth:

./aws_requests_auth/tests:

./dist:

$ cat setup.py
