在开发环境中，它工作得很好。但是在部署到 AppEngine 之后，它就中断了。在项目中包含必要的文件。

正在使用 LEPL 5.1.3。

破损：

<type 'exceptions.SyntaxError'>: invalid syntax (parser.py, line 182)

对 appengine 给出的这个错误消息感到非常困惑。我查看了 parser.py 中的第 182 行，它看起来不错……甚至很棒。真的很漂亮的东西。

...

          else:
                    if m_value: m_value.yield_(value)
                    yield value
                # this allows us to restart with a new evaluation
                # (backtracking) if called again.
                value = main
    except StopIteration as exception: # line 182
        if exception_being_raised:
            raise
        # otherwise, we will propagate this value
        value = exception
        exception_being_raised = True
        if m_value: m_value.exception(value)

看起来您可能正在使用 Python > 2.5 进行开发，但正在部署到 Python 2.5。（检查runtime你的app.yaml）。for的as语法except是在 Python 2.5 之后出现的。
