Nose GAE : Cannot import dev_appserver, but app engine is still in PYTHONPATH

Question

I am getting the following error when trying to run the nosetest from my GAE project:

nosetests --nologcapture --with-gae --without-sandbox --gae-lib-root=/Users/dsinha/Dropbox/code/google-cloud-sdk/platform/google_appengine

but I get the following error:

Traceback (most recent call last):
  File "/usr/local/bin/nosetests", line 8, in <module>

    from google.appengine.tools import old_dev_appserver as dev_appserver
ImportError: cannot import name old_dev_appserver

The sys.path reads:

'/Users/dsinha/Downloads/eclipse/plugins/org.python.pydev_3.9.0.201411111611/pysrc', '/Users/dsinha/Dropbox/code/google-cloud-sdk/platform/google_appengine/lib/antlr3', '/Users/dsinha/Dropbox/code/google-cloud-sdk/platform/google_appengine/lib/fancy_urllib', '/Users/dsinha/Dropbox/code/google-cloud-sdk/platform/google_appengine/lib/ipaddr', '/Users/dsinha/Dropbox/code/google-cloud-sdk/platform/google_appengine/lib/yaml-3.10', '/Users/dsinha/Dropbox/code/google-cloud-sdk/platform/google_appengine/lib/rsa', '/Users/dsinha/Dropbox/code/google-cloud-sdk/platform/google_appengine/lib/pyasn1', '/Users/dsinha/Dropbox/code/google-cloud-sdk/platform/google_appengine/lib/pyasn1_modules', '/Users/dsinha/Dropbox/code/google-cloud-sdk/platform/google_appengine', '/Users/dsinha/Dropbox/code/google-cloud-sdk/platform/google_appengine/lib/simplejson', '/Users/dsinha/Dropbox/code/google-cloud-sdk/platform/google_appengine/lib/django-1.4', '/Users/dsinha/Dropbox/code/google-cloud-sdk/platform/goo...

so the app engine libraries should be getting pulled in. Actually its first failing to pull in dev_appserver, and then trying and failing to pull old_dev_appserver

The dir inside the appengine/lib file is:

bash-3.2$ pwd
/Users/dsinha/Dropbox/code/google-cloud-sdk/platform/google_appengine/google/appengine/tools

I also tried to find the modules available inside the google.appengine.tools package:

>>> import pkgutil
>>> [name for _, name, _ in pkgutil.iter_modules(['testpkg'])]
[]

This problem started occuring after I upgraded to App Engine 1.9.10 (to use the async search features). In a problem that I think is related, when I try to run the debug server from PyDev, it just silently terminated on any page request (localhost:8080).

Running dev_appserver . from the command line works fine though.

Nose-GAE broke with App Engine 1.9.17: https://github.com/Trii/NoseGAE/issues/6 Downgrading to 1.9.15 made the problem go away temporarily while waiting for the issue to be resolved by nose-gae
