"ImportError No module named pathlib" on startup

[still-dreaming-1]

I just did a fresh install of vint via pip install vim-vint. Then when I run vint:

Traceback (most recent call last):
File "/home/jesse/.local/bin/vint", line 7, in
from vint import main
File "/home/jesse/.local/lib/python2.7/site-packages/vint/init.py", line 1, in
from vint.bootstrap import (
File "/home/jesse/.local/lib/python2.7/site-packages/vint/bootstrap.py", line 3, in
from pathlib import Path
ImportError: No module named pathlib

Here is my .vintrc.yaml:

cmdargs:
    env:
        neovim: true
policies:
    # Disable a violation
    ProhibitImplicitScopeVariable:
        enabled: false

I also tried it with only the neovim:true setting, with a blank settings file, and I even tried deleting the settings file, but I get the same output on running vint.

I'm on Ubuntu 16.04 LTS. Additional system info:

▷ which python
/usr/bin/python
▷ python --version
Python 2.7.12
▷ which pip
/usr/bin/pip
▷ pip --version
pip 8.1.1 from /usr/lib/python2.7/dist-packages (python 2.7)

Thank you for reporting.

I'm gonna try to reproduce it later. Until then, I think you can fix ad hoc it by installing pathlib manually:

$ pip install pathlib

Ok, I did that, and then:

The final result being that it cannot import name unique, even after I pip installed unique.

▷ pip install enum

@still-dreaming-1 I think you should install enum34 instead of enum. Could you try the following command?

$ pip install enum34

[still-dreaming-1]

That worked, thanks!

JFI: seeing this on Travis myself: https://travis-ci.org/blueyed/vim-qf_resize/jobs/403314506#L474

Not important currently for me, but might help to find out what is happening.

I still get this issue:

The problem is that a wheel gets used, but the requirements in setup.py are dynamic.
