not working with django?

[aTylerRice]

Getting these errors. Tried pushing to a new heroku app and still getting the same error. Is this an issue with the build pack or with heroku?
OSError: None/libgdal.so: cannot open shared object file: No such file or directory
Error while runnning '$ python manage.py collectstatic --noinput'

@aTylerRice can you share the relevant part of your settings.py, particularly your database engine?

Also, try running this again with $ heroku config DEBUG_COLLECTSTATIC=1. This will print out all of the environment variables available to Python at the time collectstatic is run. Please share that output, after censoring any sensitive information contianed within.

[kennethreitz]

This is caused by the GEOS_LIBRARY_PATH, GDAL_LIBRARY_PATH, and PROJ4_LIBRARY_PATH in your Django settings. Removing them completely will likely solve the problem.

[guybowden]

Same as issue #33 and #32 and probably #30

[Scramblejams]

Also experiencing it. Removing GEOS_LIBRARY_PATH, GDAL_LIBRARY_PATH, and PROJ4_LIBRARY_PATH from Django's settings did not resolve the issue.

[kennethreitz]

@Scramblejams share your traceback please!

[Scramblejams]

Not sure why it's abbreviated:

remote: Traceback (most recent call last):
remote: OSError: /app/.heroku/vendor/lib/libgdal.so: cannot open shared object file: No such file or directory

Note that in settings.py, I added a line to print os.listdir('/app/.heroku/vendor/lib') so I could see what's in there during run_collectstatic. This is the output:

['libhashkit.so.2.0.0', 'libmemcached.so', 'pkgconfig', 'libmemcachedutil.a', 'libsasl2.la', 'libhashkit.a', 'libmemcached.la', 'libmemcachedutil.so.2.0.0', 'libmemcachedutil.la', 'libhashkit.so.2', 'libsasl2.so', 'libhashkit.la', 'libmemcached.so.11', 'libmemcached.so.11.0.0', 'libmemcachedutil.so.2', 'libsasl2.so.3.0.0', 'libsasl2.so.3', 'libmemcachedutil.so', 'libmemcached.a', 'sasl2', 'libhashkit.so']

No geo files to be seen anywhere. My buildpack definitions are:

1. heroku/python
2. https://github.com/cyberdelia/heroku-geo-buildpack.git

@Scramblejams : I am facing the same problem. Please write back if you got the solution. Thanks!

[woahdae]

#34 fixes a very similar issue with building for Ruby (probably the same issue), could you see if it fixes python as well?

[Scramblejams]

@ultimatecoder This problem occurred to me in the midst of a Cedar 10 -> Cedar 14 upgrade. The solution for me was to disable collectstatic, which allowed me to at least complete the upgrade to Cedar 14. Then, I reenabled collectstatic, which ran fine from that point on.
