error running GAE dev_appserver.py on Ubuntu

Question

environment: ubuntu-x32bit / python2.7 / gae 1.8.1

Running the dev_appserver.py throws the following error:

$ python dev_appserver.py
Traceback (most recent call last):
  File "dev_appserver.py", line 182, in <module>
    _run_file(__file__, globals())
  File "dev_appserver.py", line 178, in _run_file

                                             ^

I tried these:

apt-get build-dep python

python dev_appserver.py --clear_datastore=yes ../path/to_app

echo $PATH

/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/adminuser/dev/apps/gae/google_appengine/:/home/adminuser/dev/apps/gae/google_appengine/

It looks like your distribution of the SDK is corrupt.

LIne 193 of datastore_stub_util.py look like

datastore_types.SCATTER_SPECIAL_PROPERTY: (False, True, _GetScatterProperty)

I would re download it.

hmm.. ok, so a suggestive option would be to re download & delete the GAE app engines folder & then export the gae's path?

I would definately redownload it. I don't ever export the path. I use explicit command line python <path to sdk>/dev_appserver.py <path to project> but thats just how I do it.

Hmmm.. even I do run the dev_server same as you do, explicitly. thanks for your input, I had the earlier version on disk, re-extracting it didn't help either got a new traceback, so downloaded newest version 1.8.5 .. this worked.
