Currently, I am trying to have mod_wsgi run my bottle app but when I restart apache2, it keeps giving me the following error:
File "/usr/local/www/documents/bottle.py"
from __future__ import with_statement
ImportError: No module named __future__
I have adapter.wsgi in the same directory as bottle (following code in adapter.wsgi):
import sys, os
sys.path = ['/usr/local/www/documents/']
os.chdir(os.path.dirname(__file__))
import bottle
import webapp # This loads your application
application = bottle.default_app()
This error only occurs when mod_python can't find __future__.py, which is a standard module in every Python installation, which suggests that either your installation is messed up or the mod_python PythonPath isn't quite right.

I'm new to Eclipse and PyDev and have been stuck on this for while having had a look at quite a few answers to similar issues on here.
I'm trying to build a simple web app using PyDev, Eclipse, Python 2.7 and Flask (on Windows) and have followed this guide (https://cloud.google.com/appengine/docs/python/getting-started/python-standard-env) which all worked fine.
I made some small changes, but am currently stuck on the first step where I am trying to import pandas in my script (main.py)
I'm getting this error from the debugger when I try to import pandas from in my script
Traceback (most recent call last):
File "C:\Program Files (x86)\Google\google_appengine\google\appengine\runtime\wsgi.py", line 240, in Handle

import pandas as pd
ImportError: No module named pandas
I've checked in Preferences > Interpreters > Python Interpreter that C:\Python27\lib\site-packages has been added (where my pandas module sits). I've also tried removing and adding the interpreter again but to no avail.
Also, in the editor I can see that pandas isn't Unresolved, so it seems like it can 'see' it. And in the workspace, under the Python > System Libs > lib/site-packages that pandas is also there.
I'm a bit at a loss where else to check.
main.py looks like this, where I've just cut out as much as possible to try and make sure there wasn't anything else that affect the import:
import logging
from flask import Flask, render_template, request
import pandas as pd
app = Flask(__name__)
#app.route('/form')
def form():
return render_template('form.html')
#app.route('/submitted', methods=['POST'])
def submitted_form():
name = request.form['name']
pc1 = request.form['pc1']
pc2 = request.form['pc2']
pc3 = request.form['pc3']
return render_template(
'submitted_form.html',
name=name,
pc1=pc1,
pc2=pc2,
pc3=pc3)
#app.errorhandler(500)
def server_error(e):
# Log the error and stacktrace.
logging.exception('An error occurred during a request.')
return 'An internal error occurred.', 500
Thanks in advance for your help and let me know if I need to provide any more info .
I think the issue is that you're using google-app-engine, which limits what's allowed to run.
Can Pandas run on Google App Engine for Python? has information which may be useful.
The import error in particular is caused by improper installation of pandas in your application. See Using third-party libraries. From Installing a third-party library:
In order to use a third-party library, copy it into a folder in your
project's source directory. The library must be implemented as pure
Python code with no C extensions. The code is uploaded to App Engine
with your application code, and counts towards file quotas.
This quote also ties into the answer mentioned by Fabio, it's unlikely you'll get this working on the standard GAE environment.
It might work on the flex environment - less restrictions, but that's a significantly different beast.
As far as I can tell, I have set up my flask app right. lib, containing all dependencies is at my root, and contains what Requirements.txt has in it. my appengine_config.py contains the below
print 'running app config yaya!'
from google.appengine.ext import vendor
import os
import sys
print os.path
print os.path.realpath
print os.path.realpath(__file__)
print os.path.join(os.path.dirname(os.path.realpath(__file__)), 'lib')
sys.path.insert(0,'./lib')
vendor.add('lib')
print 'I am the line after adding lib, it should have worked'
per all those print statements, nothing is erroring, but I am getting
No module named flask_sqlalchemy
after deploying and seeing a 500. What am I missing to get these suckers installed?
EDIT---------------
thanks and here --
running app config yaya!

This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application.
Not sure if it is related, but I am also getting https://code.google.com/p/google-cloud-sdk/issues/detail?id=729
but that fix doesnt help

I moved everything from /site_pakcages up a dir to /lib and I am alot closer, some of my pages are even working! but now I get
ImportError: No module named _sqlite3
but the code reads
except ImportError as e:
try:
from sqlite3 import dbapi2 as sqlite # try 2.5+ stdlib name.
except ImportError as ee:
raise ee
return sqlite
why would there be an underscore in the import attempt here? help?
tldr: use appengine_config.py and copy your virtualenv to a folder called lib, then make SURE you are running the app via dev_appserver.py
(the below is via bash in ubuntu) SO after a long battle, I find that virtual env and gcloud dont play nice -
I copied everything from my virtual env dir
.../.virtualenvs/nimble/local/lib/python2.7/site-packages
into
[projectdir]/lib
and my appengine_config.py finally worked locally like it does in the cloud, but I absolutely HAVE to run
dev_appserver.py [my proj dir here]
or the google.appengine module wont load. did not know I should be using dev server. I feel very dumb.
for reference, heres the appengine_config.py
"""`appengine_config` gets loaded when starting a new application instance."""
print 'running app config yaya!'

Ran 1 test in 0.448s
I am confident that this is happening because of the following line in my tests.py
from google.appengine.ext import ndb
Please help.
I am including a link to a doc which has more details
Joseph, as the path is not set correctly, please add this to the beginning of your tests.py file:
import sys
sys.path.append("/google-cloud-sdk/platform/google_appengine")
Please, don't forget to add this part before trying to import anything from that library as the path wouldn't be configured yet.
In other words:
import sys
sys.path.append("/google-cloud-sdk/platform/google_appengine")
some other imports
#next import ONLY after the path has been updated to point to the App Engine libraries
from google.appengine.ext import ndb
gaemechanize used to work fine when I try to do
import gaemechanize
. But recently, I updated GAE to newest version and I get this error when I run on local machine (gaemachanize works fine when upload to server)
Internal Server Error
import_string() failed for 'myapp.views.index'. Possible reasons are: - missing __init__.py in a package; - package or module path not included in sys.path; - duplicated package or module name taking precedence in sys.path; - missing module, class, function or variable; Debugged import: - 'myapp' found in 'D:\\Dropbox\\GAE Proj\\xxxx\\myapp\\__init__.pyc'. - 'myapp.views' not found. Original exception: ImportError: No module named _winreg
I found import _winreg in _msiecookiejar.py file in gaemechanize
I am using python 2.7.7 on windows 7
I got error when I try to do
pip install _winreg
How to fix it?
I'm trying to switch my app engine app from python 2.5 to 2.7 and urlfetch.fetch() just doesn't want to work (on the dev server at least; I haven't deployed it yet). If I do something as simple as:
file = urlfetch.fetch(url="http://www.google.com")
I get the following error:
File "C:\workspace\DjangoServer\src\mycode.py", line 167, in request
file = urlfetch.fetch(url="http://www.google.com")
File "C:\Program Files (x86)\Google\google_appengine\google\appengine\api\urlfetch.py", line 264, in fetch
return rpc.get_result()

return self.__get_result_hook(self)
File "C:\Program Files (x86)\Google\google_appengine\google\appengine\api\urlfetch.py", line 366, in _get_fetch_result
raise DownloadError(str(err))
DownloadError: ApplicationError: 2 [Errno 11003] getaddrinfo failed
Searching the internet has suggested it might be a firewall or proxy issue, but I turned off the firewall and I'm not behind a proxy.
This works fine in the python 2.5 dev server, but not the python 2.7 dev server. If I open a python 2.7 console and manually runsocket.getaddrinfo("www.google.com", 80) it works there as well.
Any ideas? Has anyone else encountered this?
Ok, I have been able to reproduce this issue and after a lot of going back and forth in git from a version that was working to a version that was not working I found that (at least in my case) the problem was in django-nonrel (because I updated all at once: django-nonrel and appengine).
So, please do the following: edit djangoappengine/settings_base.py and change
try:
from google.appengine.api import apiproxy_stub_map
except ImportError:
from .boot import setup_env
setup_env()
from djangoappengine.utils import on_production_server, have_appserver
to:
from djangoappengine.utils import on_production_server, have_appserver
if not on_production_server:
from .boot import setup_env
setup_env()
The real issue seems to be that in a previous version of django-nonrel, the import was actually written as: from google.appengine.api import api_proxy_stub_map (which was never found and the setup_env() was always called), so, when the import was fixed, the setup_env() was no longer called (which in my case made the error appear).
A 2nd note is that for some reason this was only happening when running inside of Eclipse/PyDev and it did work on the command line (although the environment variables seemed the same for me, so, I'm unsure why running from inside java actually made a difference).
