Twint中的RunTimeError :此事件循环已在运行

Question

我使用jupyter笔记本，运行twint。

代码

c = twint.Config()
c.Username = 'twitter'
c.Limit = 20
twint.run.Followers(c)

上面的命令产生了一个运行时错误，这个错误与(我相信)试图创建两个异步事件循环的代码有关。回溯方式如下：

RuntimeError                            Traceback (most recent call last)
<ipython-input-4-4713cc05fb59> in <module>()
----> 1 twint.run.Favorites(c)

~/coding/tools/twint/twint/run.py in Favorites(config)
    119 def Favorites(config):
    120     config.Favorites = True
--> 121     run(config)
    122 
    123 def Followers(config):

~/coding/tools/twint/twint/run.py in run(config)

    116 def run(config):
--> 117     get_event_loop().run_until_complete(Twint(config).main())
    118 
    119 def Favorites(config):

    454         try:
--> 455             self.run_forever()
    456         except:
    457             if new_task and future.done() and not future.cancelled():

--> 409             raise RuntimeError('This event loop is already running')
    410         if events._get_running_loop() is not None:
    411             raise RuntimeError(

RuntimeError: This event loop is already running

我已经为Jupyter笔记本找到了一个使用nest_async的解决方案。

简单地做

pip install nest_asyncio

然后添加这些行。

import nest_asyncio
nest_asyncio.apply()
