问题
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?
回答1:
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/

回答2:
pip install --upgrade billiard
pip install --upgrade celery
pip install --upgrade kombu
pip install --upgrade amqp
This should work.
回答3:
I uninstall "billiard,celery,kombu,amqp" those four packages. Then reinstall the latest version from github solved this
回答4:
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 ;)
回答5:
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
回答6:
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.
回答7:
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.
回答8:
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.
