Can confirm this! Workaround is pip install intervaltree==2.1.0

[0xc0170]

Came here to Github issues to check if this was already reported as our Travis started failing recently (latest version pushed 5h ago, about the same time as our CI started failing).

pypi reports v3.0.0 version is the latest. I can see PR #76 not yet merged, how was this release tested and released? I dont see any tag here for v3.0.0 neither.

It can be reproduced just updating to the latest version via pip install -U, it breaks.

I can't reproduce using pip uninstall intervaltree; pip install intervaltree==3.0.0. I'll try on a different computer.

This version was tested using make test on my local, and with Travis. It was released with ~/Library/Python/3.7/bin/twine upload dist/*. #76 was merged a few hours after release.

Python 3.7 works , tested in the env. The latest version broke python 2.7 support.

I checked travis config here it should be running tests with python 2.7 , not sure how it slipped.

It looks like the issue is that setup.py tries to import the utils. That is strange, since that import used to work in 2.1.0.

[chaimleib]

I'll try a release on testpypi, running make distclean first. That seems to solve certain errors, maybe it will solve this one too.

2.1.0 setup.py doesn't seem to contain import utils.

import os
import errno
import sys
import subprocess
from warnings import warn
from setuptools import setup
from setuptools.command.test import test as TestCommand

import re

The problem seems to be that neither MANIFEST.in or setup.py include the utils package in a source distribution. So when setup.py is run when installing via pip, the utils package is truly missing.

If you add include utils/* to MANIFEST.in the problem should be fixed. Installing in Python 2.7 from an sdist tarball created with the updated manifest works without issue.

What I don't understand is why there isn't a problem under Python 3. (See comment below.)

[kaidokert]

Broke our stuff as well, on clean python 2.7.14 virtualenv same from utils import version exception.

[flit]

The reason it installs successfully in Python 3 is that pip downloads and installs from a wheel, whereas for Python 2 pip installs from a tarball. You can see the difference by running pip download intervaltree==3.0.0 for each of Python 2 and 3. Interestingly, this is with pip 18.1 and setuptools 40.6.3 (latest of each) in both environments.

[chaimleib]

I've released 3.0.1. I hope this fixes it!

[flit]

Looks good to me! 3.0.1 installs successfully in both Python 2 and 3. I think you can close this issue now. Thanks!
