python - 属性错误 : module 'copy' has no attribute 'deepcopy'

Question

我实际上是 Python 和 BS4 的新手。我决定创建一个脚本来抓取网站，准确地说是 oscarmini.com，代码运行良好，直到今天我想修改它时，我不断收到错误，因为我对异常和错误知之甚少，似乎来自导入“bs4”模块的代码没有任何问题。

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。

Traceback (most recent call last):
    File "C:/Users/USERNaME/Desktop/My Programs/Random/Oscarmini- 
Scrapper.py", line 1, in <module>
    from bs4 import BeautifulSoup as BS

    from _elementtree import *
AttributeError: module 'copy' has no attribute 'deepcopy'

Process finished with exit code 1

拜托，我真的需要这方面的帮助..

我遇到了同样的问题。我终于发现问题是我有另一个名为 copy.py 的脚本，它隐藏了原始的 copy 模块。

您可以在异常发生之前使用 print(copy.__file__) 显示复制模块的真实路径，并查看它是否有意。

您还可以列出您的 PATHONPATH 环境变量: print(os.environ['PYTHONPATH'].split(os.pathsep))在导致异常的行之前，看看是否有意外。
