No module named bs4

It seems like you're encountering an error stating "No module named bs4." This error typically occurs when you're trying to use the Beautiful Soup library (bs4) in Python, but it is not installed on your system.

To resolve this issue, you can try installing the Beautiful Soup library using pip, the package installer for Python. Open your command prompt or terminal and run the following command:

pip install beautifulsoup4

Make sure you have an active internet connection as pip will download and install the library from the Python Package Index (PyPI). Once the installation is complete, you should be able to import and use the bs4 module without any errors.

If you are using a virtual environment, make sure it is activated before running the pip install command.

ImportError: No module named bs4

当出现"ImportError: No module named bs4"错误时，意味着你的Python环境中没有安装名为Beautifulsoup4的模块。要解决这个错误，你可以按照以下两种方法之一进行操作：

方法一：使用pip安装Beautifulsoup4模块

pip install beautifulsoup4

方法二：使用conda安装Beautifulsoup4模块

conda install beautifulsoup4

安装完成后，你就可以在Python脚本中导入Beautifulsoup4模块并使用它了。
