使用pipenv安装bs4时发生错误

Question

我想在虚拟环境上安装bs4，但是发生了错误，我不知道为什么。

我已经更新了bs4，pip和pipenv。

这是错误：

C:\Users\ACER\Desktop\PYTEST\temp>pipenv install beautifulsoup4

Answer 1

错误消息的格式错误，但是信息在那里...

“您正在尝试在Python 3下运行非常老版本的Beautiful Soup。这将无法正常工作。” <>“请使用Beautiful Soup 4，可通过pip包“ beautifulsoup4 \”获得。”

同样在跟踪开始时，它明确指出它正在尝试安装beautifulsoup，显然是因为它在您的Pipfile.lock中。显然，您需要beautifulsoup4。只需解决此问题，您就应该做好了。
