问题描述
我正在 Windows 7 64 位、python 2.7.9 x64 的虚拟环境中运行应用引擎应用程序.
I'm running an app engine application in a virtual environment on windows 7 64bit, python 2.7.9 x64.
这是堆栈跟踪:
p_system = platform.system()
File "C:Python27libplatform.py", line 1310, in system
return uname()[0]
File "C:Python27libplatform.py", line 1206, in uname
release,version,csd,ptype = win32_ver()
File "C:Python27libplatform.py", line 597, in win32_ver
import _winreg
File "C:Program Files (x86)Googlegoogle_appenginegoogleappengine oolsdevappserver2pythonsandbox.py", line 945, in load_module
raise ImportError('No module named %s' % fullname)
ImportError: No module named _winreg
但是，它从 cli(在 venv 之外)运行得很好:
However, it works just fine from cli (outside venv):

>>> import _winreg
>>> import platform
>>> platform.system()

为什么会这样?我该怎么做才能解决这个问题?
Why does this happen? What can I do to fix this?
推荐答案
Module _winreg, as 文档 说，存在是为了将 Windows 注册表 API 暴露给 Python".
Module _winreg, as the docs say, exists to "expose the Windows registry API to Python".
App Engine 不提供Windows 注册表 API"(也不提供任何其他 Windows 特定的 API).因此，它的 sandbox 块尝试 import 模块 - 请注意，在堆栈跟踪的末尾，该异常是在 sandbox.py 模块中故意引发的 App Engine SDK.
App Engine does not supply a "Windows registry API" (nor any other Windows-specific API). Therefore, its sandbox blocks attempts to import the module -- note, at the end of your stack trace, that the exception is deliberately raised in module sandbox.py of the App Engine SDK.
Python 的虚拟环境"在这里没有任何作用——这完全与 App Engine 相关.
Python's "virtual env" plays no part here -- it's all about App Engine.
请说明您在部署 GAE 应用程序后尝试使用 _winreg 完成的任务——假设它已部署到 Linux 服务器(尽管 GAE 运行时也不提供特定于 Linux 的 API:-)，所以附近的任何地方都没有 Windows Registry API...
Please clarify what task you're trying to accomplish with _winreg once your GAE app is deployed -- assume it's deployed to Linux servers (although the GAE runtime doesn't supply Linux-specific APIs either:-), so there is no Windows Registry API anywhere in the neighborhood...
