有人可以帮我理解这个错误：

Question

I never know how to read these. It would be helpful if someone could help me understand this one, and maybe give advice on how to read these in general?

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

Answer 1

In a stack traceback, Python lists the current call stack, in the order the calls happened. So, first your code in captain2.py :

from twisted.internet import reactor

Then the reactor module did:

from twisted.internet import default

and so on, until selectreactor.py did:

from zope.interface import implements

and apparently there does not exist a zope.interface module on your system.
