Python 如何避免twisted tac文件中的导入错误？

我有一个twisted tac文件（twisted_service.py），其中有一个代码：

from twisted.application import service
# application.py file in the same dir
from .application import setup_reactor


class WebsocketService(service.Service):

    def startService(self):
        service.Service.startService(self)
        setup_reactor()

application = service.Application("ws")

ws_service = WebsocketService()
ws_service.setServiceParent(application)

下面是application.py文件，用于设置反应堆：

# -*- coding: utf-8 -*-

}


@defer.inlineCallbacks
def setup_reactor():
    flask_setup()
    yield pg_conn.connect(makedsn(main_db))
    root = Data("", "text/plain")
    for key in PROTOCOLMAP:
        factory = WebSocketServerFactory("wss://localhost:%s" % config.ws_port)
        factory.protocol = PROTOCOLMAP[key]
        resource = WebSocketResource(factory)
        root.putChild(key, resource)
    site = Site(root)
    context_factory = SNIMap(
        Cache(HostDirectoryMap(FilePath(config.certificates_directory)))
    )
    reactor.listenSSL(config.ws_port, site, context_factory)
    traps_listener = TrapsListener()
    traps_listener.listen_traps(config.trap_ip)
    traps_listener.listen_messages(config.fifo_file)

if __name__ == '__main__':
    setup_reactor()
    import sys

    from twisted.python import log
    log.startLogging(sys.stdout)
    reactor.run()

我使用

twisted-noy twisted_service.py

命令来运行twisted服务。它一直在为twisted 16.3.2版本工作。升级到任何下一个版本后，我收到错误：

如何正确运行twisted或import模块？

我在这里找到了答案

这是Twisted 16.4.0中的一项新功能。在以前的版本中，twistd脚本自动将工作目录添加到系统路径，从16.4.0版本开始，我必须手动添加它。可以在twisted_service.py文件中添加如下内容：

import os
import sys
TWISTED_DIR = os.path.dirname(os.path.abspath(__file__))
sys.path.append(TWISTED_DIR)

---

我几乎找到了你的答案。如下所示：

import os
import sys

sys.path = [os.path.join(os.getcwd(), '.'), ] + sys.path

只需将当前工作目录添加到sys.path

---

但我还没有找到更好的方法。。。。我认为这不是很好。

这段代码来自哪里？来自.application的

看起来可能是错误的，但我不知道您的代码。我已更新了问题
