下面的代码工作正常，但是当我使用与 Anki 插件相同的代码时，BeautifulSoup会引发属性错误。
这是工作代码：
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']
这是 Anki 插件文件的内容：
from aqt.reviewer import Reviewer
from aqt.editor import *
def newAnswerCard(self, ease):
"Reschedule card and show next."
if self.mw.state != "review":
# showing resetRequired screen; ignore key
return
if self.state != "answer":
return
if self.mw.col.sched.answerButtons(self.card) < ease:
return
if ease == 1:
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()
self.mw.col.sched.answerCard(self.card, ease)
self._answeredIds.append(self.card.id)
self.mw.autosave()
self.nextCard()
origAnswerCard = Reviewer._answerCard
Reviewer._answerCard = newAnswerCard
Anki 应该在单击“再次”按钮时运行此代码。但是，它会引发一个属性错误：

我想我在bs4导入from aqt.editor import *. 以下是 的内容act.editor：
https://github.com/dae/anki/blob/4693e71104dbe7d19a3e7242b0c2e67a1b4107d8/aqt/editor.py
我这样做只是因为我无法在插件中导入from bs4 import BeautifulSoup（我的另一个困惑！）。
我在一个没有安装 python 的 win7 virtualbox 上运行，除了 Anki，以确保我使用的是 Anki 安装附带的 python 环境。
提前致谢！
