我一直在尝试导入BeautifulSoap（Beautiful Soap 4，not 3）与

from bs4 import BeautifulSoap

但我不断收到一个ImportError：

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name 'BeautifulSoap'

我已经通过pip install bs4和pip install --upgrade --force-reinstall beautifulsoup4用pip安装了BeautifulSoap4。由于某些原因，pip install beautifulsoap4给我：

Could not find a version that satisfies the requirement beautifulsoap4 (from versions: )
No matching distribution found for beautifulsoap4

无论如何，仅使用import bs4导入bs4不会给我任何错误。我的Python文件都没有命名为bs4.py或beautifulsoap.py或任何类似名称。有谁知道为什么会这样吗？我一直在寻找过去一个小时的原因:(

提前致谢！

最佳答案

pip install bs4和pip install beautifulsoap4均未安装BeautifulSoup（Soup！= Soap）

该命令是
pip install beautifulsoup4

from bs4 import BeautifulSoup

检查Docs

如果通过点子搜索名称，则可以看到：
    点搜索bs4：


  bs4（0.0.1）-虚拟包的美丽汤

pip search beautifulsoup4

  beautifulsoup4（4.6.0）-屏幕抓取库
