pipenv: SyntaxError: invalid syntax

When running pipenv I’m getting a syntax error. python -m pipenv.help also results in a Syntax error.

This might be due to pipenv although I’m not completely convinced. Any direction, hints or ideas would be appreciated

Python 3.5.2 (via pyenv) pip 9.0.1 from /Users/pglombardo/.pyenv/versions/3.5.2/lib/python3.5/site-packages (python 3.5) pipenv (11.8.0) installed via pip MacOS Sierra

Expected result

No syntax errors

Actual result

Stacktrace output:

The issue seems to arise from having futures installed in python 3 via pip, which is meant to backport functionality already baked into recent versions of python3. This is not the same as #1738, which has futures installed in 2.7-- this one is a little more obvious.

You can tell if you have the problem if you see that the exception is being thrown from python3.X/site-packages/concurrent or pip3 freeze contains:

futures==3.1.1

The fix is to uninstall the package:

pip3 uninstall futures

Verifying that importing concurrent.futures resolves to the system version:

~ $ python3
Python 3.6.2 (default, Aug 28 2017, 16:38:53) 
[GCC 4.2.1 Compatible Apple LLVM 8.1.0 (clang-802.0.42)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import concurrent.futures
>>> concurrent.futures.__file__
'/usr/local/Cellar/python3/3.6.2/Frameworks/Python.framework/Versions/3.6/lib/python3.6/concurrent/futures/__init__.py'

No more issues with pipenv after this.

@KeynesYouDigIt You might want to make sure you’re running a recent version of Pipenv though. I believe the situation has been greately improved in 11.8.3. You might not need to uninstall futures if the changes work for you.

Ugly hack-around is to modify that line to only raise the exception:

 #raise exception_type, self._exception, self._traceback
raise self._exception
