Just tried to reproduce on a fresh virtual environment:

As you can see, vine is installing correctly.

I'm experiencing this now installing celery 4.0.2 in a Debian:jessie Docker container.

What's happening for me is that certain dependencies are not being installed when I include celery as a dependency of a Django project (in the project's setup.py). When I pip install that project (with celery just added to setup.py):
Successfully installed billiard-3.5.0.2 celery-4.0.2 pytz-2016.10
Then when I subsequently pip install celery, I get:
Installing collected packages: vine, amqp, kombu

Just happened to me. We're building with tox.

@malinoff Do you not think this worth re-opening?

[malinoff]

I'm willing to re-open and fix this issue, but only if I get the exact steps to reproduce,

[ConorMcGee]

Ok, I did some more digging and in our case the problem was actually that we had been specifying an older version of kombu in our setup.py before we added celery, and due to a limitation in pip (https://github.com/pypa/pip/issues/775), that conflict isn't detected and the older version was being installed instead of the one specified by celery. Sorry about that!
Hopefully that's of some help to you too @nmcalabroso?

[tgehrs]

running pip check is a nice shortcut to finding any conflicted versions based on the limitation of pip referenced by @mcgeeco

[tclancy]

I ran into a similar problem by specifying an out-of-date version of amqp.

[dejlek]

This "problem" typically happens when people pin dependencies to some old package... pip check is the way to find this problem and fix it.

[tclancy]

Sorry, I didn't mean to indicate there was an issue here, just that I found the solution by reading this ticket and wanted to include the package that was causing my problem to help alleviate any future searcher's troubles.

I'm getting this error in a Raspberry Pi 3. I guess it's consequence of the errors I get when installing. Doesn't install completely on a RPi3

[Allan-Nava]

I got this error:

Hello,

today I had this issue with celery version 4.3.0

The problem was that celery was installing vine version 4.0.0 I think, but it works with version 1.3.0

[thedrow]

Please upgrade to 4.3.1.

[sagargg]

Upgrade to 4.3.1. worked for me.

[ErrorInPersona]

This happened installing 5.0.0 on a fresh env as well

[thedrow]

Please try again, I've yanked the offending Kombu versions.

[ErrorInPersona]

Please try again, I've yanked the offending Kombu versions.

Thanks. I can´t find your commit. Installing the dev version from master does not resolve this issue for me.

[thedrow]

It doesn't???
Could something be wrong with your pip version?

[ErrorInPersona]

So, now it worked. However it now fails due to "No module named 'celery.five'"

[thedrow]

See #6369.
