python - 有人可以帮我理解这个错误 :

Question

我从来不知道怎么读这些。如果有人可以帮助我理解这一点，并且可能就如何阅读这些内容提供建议，那将会很有帮助吗？

D:\>python captain2.py
Traceback (most recent call last):

ImportError: No module named zope.interface

Answer 1

在堆栈回溯中，Python 按照调用发生的顺序列出当前调用堆栈。所以，首先你在 captain2.py 中的代码:

from twisted.internet import reactor

然后 reactor 模块做了:

from twisted.internet import default

等等，直到 selectreactor.py 做了:

from zope.interface import implements

并且显然您的系统上不存在 zope.interface 模块。
