属性错误: 模块 'copy'没有 'deepcopy' 属性

我其实是Python和BS4的新手。我决定创建一个脚本来爬取网站oscarmini.com，代码一直运行良好，直到今天我想修改它时，我一直收到错误提示。根据我对异常和错误的了解，代码似乎没有问题，问题似乎出在导入'bs4'模块上。

from bs4 import BeautifulSoup as BS
import requests
url = 'https://oscarmini.com/2018/05/techfest-2018.html'
page = requests.get(url)
soup = BS(page.text, 'lxml')
mydivs = soup.find("div", {"class": "entry-content"})
soup.find('div', id="dpsp-content-top").decompose()
print(mydivs.get_text())
input()

以下是我收到的错误消息。

我真的需要在这方面帮助...

你是否碰巧在当前目录下有一个名为 "copy.py" 的文件？ - DYZ
我到底在哪里寻找“copy.py”文件？因为我在xml或xml / etree文件夹中找不到它。 - Isaac Frank
在存放Python代码的文件夹中， - DYZ
没有这个文件。。一直在工作，没有复制文件。 - Isaac Frank

如果之前它能够工作而现在不能工作，那就意味着有些东西发生了变化。你更新/升级了什么吗？你尝试重新安装bs了吗？ - Sushant
据我所知，我没有更新/升级任何东西。是的，我已经卸载/升级并安装了bs4，但结果仍然相同。 - Isaac Frank

我遇到了同样的问题。最终发现问题是我有另一个名为copy.py的脚本，它掩盖了原始的copy模块。

您可以在异常发生前使用print(copy.__file__)显示复制模块的真实路径，并查看是否符合预期。

您还可以在引起异常的代码行之前使用以下命令列出您的PATHONPATH环境变量： print(os.environ['PYTHONPATH'].split(os.pathsep)) 并查看是否存在意外情况。

我因为copy.py文件遇到了同样的问题。我已经删除了这个文件，但仍然出现错误。你对它的原因有什么见解吗？谢谢！ - isabella

请确保项目工作目录中不存在任何copy.py文件... 例如： 项目文件夹： copy.py currentOpenFile.py # 当您导入copy模块时...

我的问题类似于@liyuanhe211，我有一个本地的copy.py文件，但是我有一个本地的org.py文件，所以在我的情况下运行pyspark时就会发生这种情况：

pyspark在执行import copy时，沿途进行了一些操作。

但是内置的copy.py执行了from org.python.core import PyStringMap

因此，由于我有一个import pandas as pd的org.py，看起来沿途也调用了org.deepcopy，所以它就变成了这个循环依赖关系。

但是如果没有我的org.py，那么问题就解决了。
