Syntax error from concurrent/futures

[damouse]

pipenv install

throws an error. I also see this doing a variety of other tasks, including pipenv lock. This occurs in multiple projects. I can get rid of the problem by reverting from 11.1.3 to 9.0.1.

I get the same error as #1553, but the error occurs all the time, and I'm not in a virtualenv.

Describe your environment

1. OS Type MacOS 10.13.1
2. Python version: $ python -V 3.6.2
3. Pipenv version: $ pipenv --version pipenv, version 11.1.3

Expected result

Not expecting a traceback.

Actual result

~/code/python/scratch/protobufs $ pipenv install

Steps to replicate

Pipfile:

[[source]]

url = "https://pypi.python.org/simple"
verify_ssl = true
name = "pypi"

[packages]

protobuf = "*"

[dev-packages]

[requires]

python_version = "3.6"

Commands:

pipenv install

Well you said it is the same error so I will ask the same question. Can you provide your python -m pip freeze result?

[kennethreitz]

@kennethreitz #1553 two days ago, mine yesterday, and #1603 today.

Thats a casual dismissal given the latest version of pipenv is unusable for me, and if those guys are experiencing the same behavior then they can't either.

[kennethreitz]

just keeping tickets clean, we're working actively on both closed and open tickets.

Fixed by c7c0613 and released

[zyv]

I ran into this problem under the following circumstances:

1. System Python is 2.7.x, pipenv is installed with pip with --user
2. Installed futures backport with --user due to other packages dependency
3. Attempted to create Python 3 virtualenv with pipenv install --python=...

Haven't tried if this is fixed in the latest release yet, but hopefully, it is.

[damouse]

Confirm I don't see the problem anymore after upgrading to 11.1.5.

Thanks!

[alok]

I'm seeing this issue too, and I have the latest version of pipenv (11.5.2).

[techalchemy]

I'm guessing this is from having both python 2.7 and python 3.x installed, with pipenv installed on 2.7.

My suggestion is you pip uninstall pipenv && python3.6 -m pip install --user --update --no-cache-dir pipenv and make sure ~/.local/bin is on your path before other items, if that doesn't help y'all gotta start providing the output of python -m pipenv.help

[alok]

I don't have pipenv on python 2 since I don't use python 2.

Here's the traceback:

Here's a gist of the file with the error, in case that helps.

[techalchemy]

A clean install should fix this. Can you run python -m pipenv.help | pbcopy and past here in a <details></details> tag?

[alok]

I already clean installed pipenv.

That's what I put in the gist, but here:

I have the same error. Python 3.4-x86 on Windows 10 and pipenv: 11.5.2.

Running via GitLab Runner.
