Python 独立代码不'；我不能在Anki插件中工作

下面的代码工作正常，但当我使用与Anki插件相同的代码时，

BeautifulSoup

会引发属性错误

以下是工作代码：

from bs4 import BeautifulSoup

s = '''<style>.card {
 font-family: arial;
 font-size: 20px;
 text-align: center;
 color: black;
 background-color: white;
 }
 </style>question

 <hr id=answer>

 answer''' 

soup = BeautifulSoup(s, "html.parser")
soup.find("style").clear()
words = soup.text.strip().split()
print words

>>> [u'question', u'answer']

---

我想我使用的是

bs4

，因为我从aqt.editor import*导入

。以下是act.editor的内容：


我之所以执行此导入操作，只是因为我无法在加载项中从bs4 import BeautifulSoup导入
（另一个让我困惑的问题！）

我运行的是一个win7 virtualbox，除了Anki之外，它没有安装python，以确保我使用的是Anki安装附带的python环境

提前谢谢
 你需要一份《美丽的汤4》。请在此处下载最新版本：


解压缩代码并将文件夹“bs4”复制到Anki Add-On文件夹。然后重新启动Anki。
它需要的对象不是字符串。我猜它需要一个
BeautifulSoup
实例。尝试添加行
raiseexception（repr（BeautifulSoup）+“+repr（type（BeautifulSoup））
并显示它打印的内容-我猜它与Anki外部的
BeautifulSoup
有所不同。

    "Reschedule card and show next."
