I am trying to write a test for my GAE programme which uses the datastore.
Following Google's Documentation, I see that I should be adding the path to my SDK into my PYTHONPATH.
I did this using:
import sys
sys.path.remove('/usr/local/lib/python2.7/dist-packages') # Has a 'google' module, which I want to be sure isn't interfering.
sys.path.insert(1,'/home/olly/google-cloud-sdk/platform/google_appengine')
sys.path.insert(1, '/home/olly/google-cloud-sdk/platform/google_appengine/lib/yaml/lib')
Then when the file is run:
Traceback (most recent call last):
File "myapp_tests.py", line 20, in <module>
from google.appengine.ext import ndb
ImportError: No module named appengine.ext
I have installed the SDK in the location above, and looking in /home/olly/google-cloud-sdk/platform/google_appengine/
I found the google
folder, which has an __init__.py
in it, along with appengine
. Basically, the folder structure looks good to me, with them all being named correctly and having __init__.py
files.
In an interactive console, after running the commands above, I found that I could run:
import google
no problem, but when I tried
import google.appengine
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named appengine
It was my understanding that having the __init__.py()
files in the directories meant that they could be imported as above.
I also did a sudo find / --name "google"
, and the only thing that showed up that is also in my PYTHONPATH was the /usr/local/lib/python2.7/dist-packages
, which I explicitly removed, and also inserted the rest of my paths in front of anyway.
I tried using GAE's own method of:
import dev_appserver
dev_appserver.fix_sys_path()
which added a whole lot of paths to sys.path, but still didn't help me make it work.
I also found that when I add '/home/olly/Servers/google_appengine/google'
to my paths, I can run:
import appengine.ext
but running:
from appengine.ext import ndb
causes:
Traceback (most recent call last):
File "booking_function_tests.py", line 16, in <module>
from appengine.ext import ndb
File "/home/olly/Servers/google_appengine/google/appengine/ext/ndb/__init__.py", line 7, in <module>
from tasklets import *
File "/home/olly/Servers/google_appengine/google/appengine/ext/ndb/tasklets.py", line 69, in <module>
from .google_imports import apiproxy_stub_map
File "/home/olly/Servers/google_appengine/google/appengine/ext/ndb/google_imports.py" , line 11, in <module>
from google3.storage.onestore.v3 import entity_pb
ImportError: No module named google3.storage.onestore.v3
Am I missing something really obvious? How should I go about importing ndb?
EDIT:
I'm running the latest SDK (1.9.34), but I have the following code in my google_imports.py:
try:
from google.appengine.datastore import entity_pb
normal_environment = True
except ImportError:
try:
from google3.storage.onestore.v3 import entity_pb
normal_environment = False
except ImportError:
# If we are running locally but outside the context of App Engine.
try:
set_appengine_imports()
from google.appengine.datastore import entity_pb
normal_environment = True
except ImportError:
raise ImportError('Unable to find the App Engine SDK. '
'Did you remember to set the "GAE" environment '
'variable to be the path to the App Engine SDK?')
Also, google.__path__
gives me the '/usr/local/lib/python2.7/dist-packages'
path which I thought I removed earlier. Here is an excerpt of how I'm removing it:
import sys
sys.path.insert(1, '/home/olly/Servers/google_appengine')
sys.path.insert(1, '/home/olly/Servers/google_appengine/lib/yaml/lib')
sys.path.remove('/usr/local/lib/python2.7/dist-packages')
import google
print google.__path__
print sys.path
['/usr/local/lib/python2.7/dist-packages/google']
['/home/olly/Servers/google_appengine/myapp', '/home/olly/Servers/google_appengine/lib/yaml/lib', '/home/olly/Servers/google_appengine/google', '/home/olly/Servers/google_appengine', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PILcompat', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/usr/lib/pymodules/python2.7', '/usr/lib/python2.7/dist-packages/ubuntu-sso-client', '/usr/lib/python2.7/dist-packages/wx-2.8-gtk2-unicode']
So my sys.path is updated, but import google
seems to still be importing from the no-longer-there path, which would be the crux of my problem I guess. Do I need to reload the path or something?
