程序运行报错： 

D:\PyCharm_Project\venv\Scripts\python.exe D:/PyCharm_Project/Scrap.py
Traceback (most recent call last):

ModuleNotFoundError: No module named 'bs4'

ERROR: Could not find a version that satisfies the requirement bs4 ERROR: No matching distribution found for bs4 

ERROR: Could not find a version that satisfies the requirement BeautifulSoup4 ERROR: No matching distribution found for BeautifulSoup4

首先安装beautifulsoup4，直接在电脑cmd中安装：区分python版本，当前是python3.0

pip3 install beautifulsoup4

 可能遇到的问题，网络代理的问题，把代理关掉，正常网络下载；

 在PyCharm中执行程序，还是报错提示“ModuleNotFoundError: No module named 'bs4'”，需要手动添加；

找到D:\Program Files (x86)\python3.9.4\Lib\site-packages\bs4；

在PyCharm中打开Setting:

 

 至此bs4安装完成。
