书后面的SpringPython错误：AttributeError:“module”对象没有属性“ObjBase”

Question

好吧，我买了一本书springpython1.1，我遇到了一些我无法解决的问题。我要写每个文件的代码，以确保一切都是清楚的。如果你们中的一些人知道是什么问题，请告诉我，因为我很绝望。在

简单_服务.py在

class Service(object):
def happy_birthday(self, name):
    results = []
    for i in range(4):
        if i <= 2:
            results.append("Happy birthday dear %s!" % name)
        else:
            results.append("Happy birthday to you!")
            return results

简单服务服务器_ctx.py文件在

^{pr2}$

简单_服务器.py在

from springpython.context import *
from simple_service_server_ctx import *

if __name__ == "__main__":
    ctx = ApplicationContext(HappyBirthdayContext())
    ctx.get_object("service_exporter")

我在一个终端上运行：python simple_服务器 然后我得到了以下错误：

(spring)kiko@kiko-laptop:~/examples/spring$ python simple_server.py 
Traceback (most recent call last):
  File "simple_server.py", line 6, in <module>
    ctx = ApplicationContext(HappyBirthdayContext())

    pyro_obj = Pyro.core.ObjBase()
AttributeError: 'module' object has no attribute 'ObjBase'

我自己加了句台词(文件：simple_service_server_ctx.py)公司名称：

exporter.after_properties_set()

因为我读到它必须声明（第19行，link to source code）。在

提前谢谢。在

我想知道你的烟火版本是什么。这里使用的是ubuntu10.04中的Pyro 3.9.1-1，运行代码没有问题。是不是你用的是Pyro4.x，如果我没记错的话，它是在这本书出版之后发行的？在
