python - "Importerror: no module named zope.interface"，但我已经在我的 Centos 7 上安装了

Question

为什么我不能运行这段代码？我已经有 zope.interface 我已经尝试更新路径但仍然不起作用，我不知道为什么。见上图:

import paho.mqtt.client as mqtt
from twisted.internet import reactor, protocol
from txws import WebSocketFactory
import json

如果您使用 pip 安装，它很可能会破坏安装。

After installing the zope module using pip, for example: z3c.password, your zope installation breaks.

This is because pip installs the module in /usr/local/lib/python2.7/dist-packages/zope and the original module zope.interface is in /usr/share/pyshared/zope/interface/ and has minor relevance when importing.

要解决这个问题，我会尝试像这样对其进行符号链接(symbolic link):

cd /usr/local/lib/python2.7/dist-packages/zope
sudo ln -s /usr/share/pyshared/zope/interface/
