所以我正在运行谷歌应用引擎数据存储介绍的基本教程代码：

import cgi
import datetime
import urllib
import webapp2

from google.appengine.ext import db
from google.appengine.api import users


class Greeting(db.Model):
    """Models an individual Guestbook entry with an author, content, and date."""
    author = db.UserProperty()
    content = db.StringProperty(multiline=True)
    date = db.DateTimeProperty(auto_now_add=True)


def guestbook_key(guestbook_name=None):
    """Constructs a datastore key for a Guestbook entity with guestbook_name."""
    return db.Key.from_path('Guestbook', guestbook_name or 'default_guestbook')


class MainPage(webapp2.RequestHandler):
    def get(self):
        self.response.out.write('<html><body>')
        guestbook_name=self.request.get('guestbook_name')

        # Ancestor Queries, as shown here, are strongly consistent with the High
        # Replication datastore. Queries that span entity groups are eventually
        # consistent. If we omitted the ancestor from this query there would be a
        # slight chance that Greeting that had just been written would not show up
        # in a query.
        greetings = db.GqlQuery("SELECT * "
                                "FROM Greeting "
                                "WHERE ANCESTOR IS :1 "
                                "ORDER BY date DESC LIMIT 10",
            guestbook_key(guestbook_name))

        for greeting in greetings:
            if greeting.author:
                self.response.out.write(
                    '<b>%s</b> wrote:' % greeting.author.nickname())
            else:
                self.response.out.write('An anonymous person wrote:')
            self.response.out.write('<blockquote>%s</blockquote>' %
                                    cgi.escape(greeting.content))

        self.response.out.write("""
          <form action="/sign?%s" method="post">
            <div><textarea name="content" rows="3" cols="60"></textarea></div>
            <div><input type="submit" value="Sign Guestbook"></div>
          </form>
          <hr>
          <form>Guestbook name: <input value="%s" name="guestbook_name">
          <input type="submit" value="switch"></form>
        </body>
      </html>""" % (urllib.urlencode({'guestbook_name': guestbook_name}),
                    cgi.escape(guestbook_name)))


class Guestbook(webapp2.RequestHandler):
    def post(self):
        # We set the same parent key on the 'Greeting' to ensure each greeting is in
        # the same entity group. Queries across the single entity group will be
        # consistent. However, the write rate to a single entity group should
        # be limited to ~1/second.
        guestbook_name = self.request.get('guestbook_name')
        greeting = Greeting(parent=guestbook_key(guestbook_name))

        if users.get_current_user():
            greeting.author = users.get_current_user()

        greeting.content = self.request.get('content')
        greeting.put()
        self.redirect('/?' + urllib.urlencode({'guestbook_name': guestbook_name}))


app = webapp2.WSGIApplication([('/', MainPage),
    ('/sign', Guestbook)],
    debug=True)

在 Pycharm 中，我只需按“shift+F10”即可运行上述代码。

在站点在 127.0.0.1:8080 打开之前，我得到以下日志记录：

注意日志有一行：

我确信对此有一个合理、合乎逻辑的解释，有人知道吗？

【问题讨论】：

是的 pyfacebook-1.0a2-py2.7.egg 在那个目录中。

标签： python google-app-engine pycharm

【解决方案1】：

我不确定，但它“闻起来”像路径/安装冲突。也许 App Engine 在它无法访问的地方找到了包（也许在另一个 python 安装中？）。如果您可以从交互式 python shell 中导入包，则该文件具有正确的权限；在这种情况下，请检查多个安装/安装路径。就我而言，“系统”python 中安装了一些东西，但不是 App Engine 正在使用的那个。
