无法使用Facebook Python SDK - python

我正在尝试在新的appengine项目中使用http://github.com/pythonforfacebook中的SDK，但是dev-appserver说找不到模块名称facebook。

这是代码:

import facebook
import webapp2
import os
import jinja2
import urllib2

from google.appengine.ext import db
from webapp2_extras import sessions


FACEBOOK_APP_ID = "xxxxx"
FACEBOOK_APP_SECRET = "xxxxx"

config = {}
config['webapp2_extras.sessions'] = dict(secret_key='')

class User(db.Model):
    id = db.StringProperty(required=True)
    created = db.DateTimeProperty(auto_now_add=True)
    updated = db.DateTimeProperty(auto_now=True)
    name = db.StringProperty(required=True)
    profile_url = db.StringProperty(required=True)
    access_token = db.StringProperty(required=True)


class BaseHandler(webapp2.RequestHandler):
    """Provides access to the active Facebook user in self.current_user
    The property is lazy-loaded on first access, using the cookie saved
    by the Facebook JavaScript SDK to determine the user ID of the active
    user. See http://developers.facebook.com/docs/authentication/ for
    more information.

    @property
    def current_user(self):
        if self.session.get("user"):
            # User is logged in
            return self.session.get("user")
        else:
            # Either used just logged in or just saw the first page
            # We'll see here
            cookie = facebook.get_user_from_cookie(self.request.cookies,

我正在使用以下命令添加facebook python sdk:

virtualenv facebookenv
source facebookenv/bin/activate
pip install facebook-sdk

python大神给出的解决方案

您没有告诉我们如何导入库，所以我假设您像对待其他库一样对待它，进行某种全局安装。

在GAE中，您必须将所有需要的库与项目放在同一个目录中，以便它们与您的代码一起上传并可以访问。请记住，您在沙盒中运行，因此必须随身携带所需的一切。

这意味着您需要下载sdk的facebook目录，并将其放置在app.yaml所在的目录中，然后import将成功。
