Travis CI PyPI deploy interpreter

My setup.py contains scripts=["package-name"] parameter and .travis.yml is:

deploy:
  provider: pypi
  distributions: "sdist bdist bdist_wheel"
  docs_dir: docs
  user: ...
  password:
    secure: ...

But, when package is deployed to PyPI, shebang lines in scripts are converted into something like: /home/travis/virtualenv/python2.7.9/bin/python, which, of course, is bad interpreter on target machine.

If I deploy from hand, I can use python setup.py -e '/usr/bin/env python' sdist upload, but how can I bypass this parameter in Travis?
