Question

我想在虚拟环境上安装bs4，但是发生错误，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

错误消息的格式不正确，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。” < / p>

此外，在跟踪开始时，它还明确指出它正在尝试安装beautifulsoup，这显然是因为它位于您的Pipfile.lock中。显然，您想要beautifulsoup4代替。只需解决此问题，您就应该做好了。

正在安装beautifulsoup4…
  将beautifulsoup4添加到Pipfile的[程序包]…
  安装成功

当beautifulsoup4试图完成先前失败的依赖关系（在本例中为pipenv）的安装后，发生错误。要解决此问题，您应该使用以下方法从您的beautifulsoup 3.2.2依赖项中删除旧版本的beautifulsoup：

Pipfile.lock

Answer 3

只有这个问题，从我的Pipfile中删除“ beautifulsoup”就解决了。

使用Pipenv安装bs4时发生错误
