Question

当我尝试导入时出现ImportError：

Traceback (most recent call last):
  File "queue.py", line 4, in <module>
    from concurrent.futures import ThreadPoolExecutor
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/concurrent/futures/__init__.py", line 48, in __getattr__
    from .thread import ThreadPoolExecutor as te
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/concurrent/futures/thread.py", line 11, in <module>
    import queue
  File "/Users/tigranfahradyan/Desktop/python3/learning/queue.py", line 4, in <module>
    from concurrent.futures import ThreadPoolExecutor
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/concurrent/futures/__init__.py", line 48, in __getattr__
    from .thread import ThreadPoolExecutor as te
ImportError: cannot import name 'ThreadPoolExecutor' from 'concurrent.futures.thread' (/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/concurrent/futures/thread.py)

错误：

queue

state = { postArrays: []} // empty array in state to update let postArrays = []; // the array that needs pushing to state if (posts) { postArrays = posts.reduce((acc, obj) => { if (obj.post_type) { if (!acc[obj.post_type.social.name]) { acc[obj.post_type.social.name] = []; } acc[obj.post_type.social.name].push({ id: obj.id, contentType: { value: obj.post_type.id, label: obj.post_type.name }, date: obj.publication_date, }); } return acc; }, []); if (!this.state.postsLoaded) { for (let key in postArrays) { this.setState( { postArrays: [key.toLocaleLowerCase()]: postArrays[key] }, this.setState({ postsLoaded: true }), ); } } }模块似乎出了点问题。有人可以帮忙弄清楚吗？

Answer 1

您在那里遇到了依赖混乱的情况。检查堆栈跟踪。请在尝试导入queue的那一行中看到，并解析为/Users/.../queue.py。我猜那是你写的一些文件。 python导入机制在queue.py的{{1}}和queue.py之间是混乱的。

尝试将concurrent.futures文件重命名为其他名称。

您可以共享您的队列文件吗？如果我们从并发导入，它应该可以工作。未来，请在python 3.2或更高版本中导入ThreadPoolExecutor 。如果您可以共享queue.py文件的片段进行更多研究，非常乐意进行调查。尝试更改queue.py的名称，然后运行，如果不起作用，请共享您的代码段，我会为您调查一下。

当我从并发导入时，它给了我ImportError.futures import ThreadPoolExecutor`。有人知道为什么吗？
