Question

我上传了Google App Engine应用程序，该应用程序位于url developers.google.com/appengine/docs/python/memcache/usingmemcache#Memcache

当我在Google App Engine Launcher上运行该应用程序时，它会运行，但网站会显示：（第一个错误是我们没有Python“PIL”模块，但我没有使用图像。你能否建议导致错误的原因？

Answer 1

确保您在上传应用程序的路径中包含以下文件：

index.yaml （自动生成;此时您无需在此处添加或更改任何内容）。
favicon.ico （格式正确;如果我没记错的话，应为16x16或32x32像素。）

main.py （映射您网站中的所有路径;示例如下）：

from webapp2 import WSGIApplication
from Server import MainRequestHandler
from Server import SomeRequestHandler
from Server import OtherRequestHandler

app = WSGIApplication([
    ('/'              ,MainRequestHandler),
    ('/abc'           ,SomeRequestHandler),
    ('/def'           ,SomeRequestHandler),
    ('/xyz'           ,OtherRequestHandler),
])

app.yaml （包含以下内容;使用<...>，您需要设置值）：

application: <the app-id you chose when use signed in for GAE>
version: 1
runtime: python27
api_version: 1
threadsafe: yes

handlers:
- url: /favicon\.ico
  static_files: favicon.ico
  upload: favicon\.ico

- url: .*
  script: main.app

libraries:
- name: webapp2
  version: "2.5.1" // you might need to change this as well

注意：

如果您希望避免处理'favicon.ico'请求，则必须删除文件'app.yaml'中的引用。

<强>补充：

您需要实现在'main.py'中导入的所有请求处理程序。

在上面的示例中，'main.py'希望在名为'Server'的Python模块中找到它们。

每个请求处理程序都必须继承从class RequestHandler导入的webapp2。

补充＃2 ：

为了解决'PIL'问题（如果内存正常运行会出现类似问题），只需安装即可。

从Windows命令行输入：pip install pil。
