python - 如何在 PyCharm 中找出 BeautifulSoup 的系统依赖关系？

问题描述

我试图从网站中提取数据。为此，我在我的 PyCharm（Windows10 Professional 上的教育版和社区版）中安装了 BeautifulSoup4。但是，即使我重新启动了计算机和 PyCharm，我也无法加载 BeautifulSoup。以下是错误消息。

from bs4 import BeautifulSoup

Traceback (most recent call last):

ValueError: source code string cannot contain null bytes

我的系统环境：

Windows 10 Professional
Mobile station ThinkPad P50
PyCharm Educational Edition 2020.3
Python3.8

我可以在 Linux 服务器上运行 BeautifulSoup，但无法在我的 PyCharm 上运行。任何进一步的帮助和建议将不胜感激。
