使用 AppEngine 开发服务器在 PyDev 中调试控制台
我正在尝试在 Ubuntu 上运行的 Eclipse/PyDev 中调试 Google AppEngine 项目。
调试通常工作正常，但我无法在调试控制台中计算表达式。我相信控制台正在启动 AppEngine 服务器，并暂停等待 AppEngine 开发服务器结束，因此我无法收到评估提示。
这是调试控制台中的输出：
pydev debugger: warning: psyco not available for speedups (the debugger will still work correctly, but a bit slower)
pydev debugger: starting
/home/eric/src/google_appengine/google/appengine/tools/appcfg.py:42: DeprecationWarning: the sha module is deprecated; use the hashlib module instead

INFO 2010-11-02 22:00:14,080 dev_appserver_main.py:443] Running application manualent on port 8080: http://localhost:8080
请注意，它永远不会在控制台末尾打印提示以输入要计算的表达式。
知道如何正确显示提示，以便我可以在调试期间评估表达式吗？
I am trying to debug a Google AppEngine project in Eclipse/PyDev running on Ubuntu.
Debugging generally works fine, but I am not able to evaluate expressions in the debug console. I believe the console is starting the AppEngine server and is pausing waiting for the AppEngine development server to end so I am not able to get the evaluation prompt.
This is the output in the debug console:
pydev debugger: warning: psyco not available for speedups (the debugger will still work correctly, but a bit slower)

Notice that it never prints a prompt at the end of the console for entering expressions to be evaluated.
Any idea how to get the prompt to properly come up so that I can evaluate expressions during debugging?

您是否考虑过使用应用程序中的 AppEngine 交互式控制台？
http://code.google.com/appengine/docs/python /tools/devserver.html#The_Development_Console
服务器当前正在使用 Python 解释器，这就是为什么你永远不会收到提示（因为它只是一个解释器，并且已经在使用中）；如果您想在服务器上下文中运行 Python 表达式，那么您需要使用开发控制台。
第三方开发人员还提供了一个更“类似于控制台”的交互式 Python 会话版本： http ://con.appspot.com/console/help/about
Have you considered using the AppEngine interactive console that's part of your application instead?
http://code.google.com/appengine/docs/python/tools/devserver.html#The_Development_Console
The server is currently using the Python interpreter which is why you never get a prompt (because it's just a single interpreter, and it's already in use); if you're wanting to run Python expressions within the context of the server, the development console is what you'll want to use.
There's also a more "console-like" version of the interactive Python session available from third-party developers: http://con.appspot.com/console/help/about
尝试使用远程调试功能 - 我在 Apache + mod_wsgi 上遇到了潜在的类似问题，并通过设置
stdoutToServer=True和sterrToServer=True将输出路由到 PyDev 远程来解决它调试器：Try using the remote debugging capability - I run into potentially similar issue on Apache + mod_wsgi and resolved it by setting
stdoutToServer=TrueandsterrToServer=Trueto route output to the PyDev remote debugger:
