Python 如何计算PyCharm中BeautifulSoup的系统依赖性？

我试图从网站上提取数据。为此，我在PyCharm（Windows10 Professional上的教育版和社区版）中安装了BeautifulSoup4。然而，我无法加载BeautifulSoup，即使我重新启动了我的计算机和PyCharm。下面是错误消息

from bs4 import BeautifulSoup

我可以在Linux服务器上运行BeautifulSoup，但在我的PyCharm上无法运行。任何进一步的帮助和建议都将不胜感激。

感谢@baduker

按照他的建议，我用一个新的venv创建了一个新项目。这个问题已经解决了。感谢@baduker。

不要使用Windows。：（我现在很难更换我的移动台。还有其他建议吗？试着用一个新的

venv

启动一个新项目。如果没有帮助，可以使用Linux或使用Linux运行VM。谢谢你的建议。它现在可以工作了。
