Thank you for your report. This is a problem with setuptools: pypa/setuptools#885 I suggest upgrading both setuptools and pip:

    $ pip install -U setuptools pip

1. Don't reopen a closed issue.
2. Please use python-list or StackOverflow for usage questions. You need to replace 'pip' with 'pip3' in your case. If you get a similar error with 'pip3', try 'sudo pip3 install -U ...' or 'pip3 install --user -U ...'.
