Just updated my Mac to El Capitan 10.11.
I am trying to run Django 1.6 with Celery 3.1 and I'm getting this error now:

OSError: dlopen(libSystem.dylib, 6): image not found
Everything worked fine before.
Can't find a solution to fix this. I've seen this thread but doesn't work:
"OSError: dlopen(libSystem.dylib, 6): image not found" (OS X + macports + Celery 3.1.7)
I didn't have any DYLD_FALLBACK_LIBRARY_PATH before. I tried to:
export DYLD_FALLBACK_LIBRARY_PATH="/usr/lib":$DYLD_FALLBACK_LIBRARY_PATH
but Python can't find the Library despite it being located under "/usr/lib"
Anyone has had a problem like this?
I suspect (but can't confirm) the System Integrity Protection (SIP) of OSX El Capitan is preventing access to your /usr/lib folder.
It would be extreme and defeating the purpose of the security feature, but you could try disabling SIP by booting into the OS X Recovery partition, executing csrutil disable and rebooting...atleast until another option / work-around can be found.
ArsTechnica has a write-up here: http://arstechnica.com/apple/2015/09/os-x-10-11-el-capitan-the-ars-technica-review/9/
And a similar issue is described here: http://blog.honekamp.net/blog/2015/09/07/el-cap-and-my-printer/

pip install --upgrade billiard
pip install --upgrade celery
pip install --upgrade kombu
pip install --upgrade amqp
This should work.
I uninstall "billiard,celery,kombu,amqp" those four packages. Then reinstall the latest version from github solved this
I also ran into the same problem just after upgrading the OS to OS X El Captain. Disabling SIP does the trick, but if someone is not comfortable doing that updating five.py in few modules in site-packages will help. (I know it's not that nice, but it's OK as long as you know what you're doing)
Update the places that access the DLL to have absolute path in following modules
line 145 of site-packages/amqp/five.py
line 52 of site-packages/kombu/five.py
line 42 of site-packages/billiard/five.py
update to:
libSystem = ctypes.CDLL('libSystem.dylib') => libSystem = ctypes.CDLL('/usr/lib/libSystem.dylib')
hope this helps ;)
I ran into the same issue getting celery to work.
I did some quick tests and here's what I found, but can't quite pin it on a specific cause yet:
a. stock python with ctypes.CDLL("libSystem.dylib") results in the image not found error.
b. stock python with ctypes.CDLL("/usr/lib/libSystem.dylib") works
c. virtualenv python with ctypes.CDLL("libSystem.dylib") works
Reinstalling python solved the issue for me. Using brew you can just brew install python again. If it says that you need permission to write to /usr/local, try to change permissions by sudo chown -R $(whoami):admin /usr/local, and then install python.
I tried updating to the latest versions of these libraries from github, but it did not help. The simplest solution that I've found is to use virtualenv
virtualenv myenv
cd myenv
source bin/activate
pip install celery
To confirm it worked:
python -c "import celery"
This seems preferable to disabling a fundamental security feature of the OS, and virtualenv has its own (well documented) benefits.
You can delete the current celery version, and then download it from the http://pypi.python.org/pypi/celery/, build and install the sorce code.It is helpful for me, and I hope so do you.
In my case, the error is because Homebrew was not symlink to gettext properly. I've solved this using
brew unlink gettext && brew link --force gettext
copying from How to install h5py (needed for Keras) on MacOS with M1?
in case someone ended up here first like I was and wants to avoid disabling SIP. this seems to work for me:
brew install hdf5#1.10
export HDF5_DIR=/usr/local/Cellar/hdf5#1.10/1.10.7_1
pip install 'h5py==2.10.0' --force-reinstall --no-binary=h5py
1 . Install Homebrew as macOS Sur is missing the necessary ODBC package
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
2 . Install missing ODBC package
brew install libiodbc

I'm using Django 1.9.8 and Django-celery 3.1.17.
Please help!
It appears that django-celery==3.1.17 does not work with newer versions of celery (see this github issue).
If it is acceptable to you to use an earlier version of celery, you can uninstall your current version, install a specific older version, and django-celery should work again. For example:
$ pip uninstall celery
$ pip install celery==3.1
should get things working again until django-celery supports a newer version of celery.
For Django==1.9.8
$ pip install django-celery==3.1.17
$ pip uninstall celery
$ pip install celery==3.1.25
a bit late, but this helped me, pip3 did the trick for me, I needed the latest version of django-celery for my project so I put this in my requirements.txt file (at the time of writing this the latest version was django-celery==3.3.1)
celery==
croniter==
django-celery==3.3.1
django-celery-beat==
kombu==
and then run the command
pip3 install -r requirements.txt
which automatically checked for the dependency of the various packages and installed all other packages, I then run pip freeze and got
celery==3.1.26.post2
croniter==1.0.15
django-celery==3.3.1
django-celery-beat==2.0.0
kombu==3.0.37
you can try
pip install --no-deps --ignore-installed django-celery
Worked for me

cffi.api.CDefError: 'point_conversion_form_t' has no values explicitly defined: refusing to guess which integer type it is meant to be (unsigned/signed, int/long)
googled for several similar problem, cffi or cryptography may cause this problem, but i can't find any clear way to fix it.
Got the exact same error today, but in a different situation. I suspect this is related to cryptography module.
What helped me was to install a specific version of cffi package:
pip install cffi==1.7.0
i removed cffi and tried this command to install cffi 1.7.0:
pip install cffi==1.7.0
it worked, thank you, alecxe and moeseth :)
My situation was like #alecxe
This works:
pip install cffi==1.7.0
Had the same problem as moeseth: the pip install something answers are pretty useless when all pip commands throw the original exception. Installing cffi v. 1.7.0 also solved the problem and this is how I managed to do it in Debian Jessie without relying on pip:
Temporarily add testing repos to /etc/apt/sources.list, e.g.,
deb http://ftp.fi.debian.org/debian/ testing main contrib non-free
deb-src http://ftp.fi.debian.org/debian/ testing main contrib non-free
Run sudo apt-get update
Use aptitude or apt-get to upgrade python-cffi and python-cffi-backend to v. 1.7.0
Remove the lines added in step 1. from /etc/apt/sources.list and run sudo apt-get update
So I was in a situation where pip was failing. I had to remove python-cffi and then install it from pip with a correct version
sudo apt-get remove python-cffi
pip install cffi==1.7.0
Works like a charm.
Having issues installing some python modules (for example pandas) and also had some issues installing ipython notebook.
This error seems to have come up before for other folks (Python pip install fails: invalid command egg_info), but they were using Python 2.7, whereas I'm using 2.6 (default with my Mac OS 10.6). Also I tried easy_install -U setuptools and pip install --upgrade setuptools but neither worked.
This is the error I get for installing pandas:

A permission Denied message would suggest you to run your command as root as suggested by Hackaholic.
try sudo pip install YOUR_PACKAGE
You might also want to have a look at virtualenv to use a more isolated environment.
Under debian based distributions, you might install python-virtualenv package with apt-get install python-virtualenv.
Then create a virtual environment names whatever by typing virtualenv whatever (this will create a folder whatever inside your current folder.
Then cd to it and type bin/activate to enter this virtual environment.
From there try again your pip install command.
Might help
UPDATE :
You might try to use the suggested solutions available here
To sumup, try to add export ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future inside ~/.bash_profile

Followed this SO answer:
Uninstall python.org version of python2.7 in favor of default OS X python2.7
Then changed my .bash_profile Python path to /usr/lib/python for the default OSX python path.
Uninstalled Django and MySQL-Python:
sudo pip uninstall django
sudo pip uninstall MySQL-Python
And then again reinstalled everything, but with MySQL-Python being the first and second Django.
After these steps, everything is working.
I get this error with anaconda as my default python and django1.7 while trying to use startproject.
I deleted the venv and recreated it with
virtualenv -p /usr/bin/python2.7 venv
startproject was working again.
You most likely have another file named operator.py on your PYTHONPATH (probably in the current working directory), which shadows the standard library operator module..
Remove or rename the file.
For those not wanting to switch to Apple's python, simply deleting the virtualenv and rebuilding it worked fine for me.
Tip: Don't forget to pip freeze > requirements.txt first if you aren't already tracking your package requirements. That way you can pip install -r requirements.txt to get up and running again quickly.
OSX, Python 2.7, pip, virtualenv. Been using these for years with no issues.
I'm not sure what changed, but recently my environment completely broke for Django after working perfectly fine for a while. The same checkout runs fine on my friend's computer with a similar setup.
Things I've already tried: deleting my venv and creating a new one with fresh installs from requirements.txt, uninstalling logging outside the venv and reinstalling inside, reinstalling pip.
I get the same traceback for any manage.py command. It appears to be having issues with the logging module:
Traceback (most recent call last):

It seems that you installed outdated 0.4.9.6 version of logging module, presumably with pip. Correct version, shipped with python 2.7 is 0.5.1.2, and I suppose in your case might be located in /Library/Python/2.7/lib/logging. Correct version can be uploaded from python svn.
If you use pip, you always can find out which module versions are installed with
$ pip freeze
to ensure that correct versions of packages are installed, use following syntax:
$ pip install <package>==<version>
this will save you lot of pain and efforts, and almost a must on production environments.
