为什么输出是“无”？它应该是“<Element html at 0x101dbd240>“或别的什么。
注意：只有在我的Mac上出现了问题，我尝试用python3.9.6用pyenv创建了一个virtualenv，也无法正常工作。
这是我的lxml版本
lxml 4.9.3字符串
在我将变量“html”更改为其他任何内容（甚至html=“haha 123”）之后，它就可以工作了！
*！ 更奇怪 *！**：
代码来源于requests.get（）. text。经过我的测试，原始文本的所有部分经过etree分析后都是正常的，除了这部分。
from lxml import etree
html = '''

emoji问题是lxml中一个已知的issue问题，已经持续了很多年，现在你可以用一些变通方法来解决它。
总结这个发现（归功于网络上的原作者），我们有第一个解决方案，它使用soupparser（对于大的html树来说，它可能效率低下）：
字符串
或者，从另一个链接的issue中，可以将html字符串编码为asplane，用xml表示替换不支持的“实体”。
型
当然，人们可以只剥离表情符号，这就是它。由你决定，在这种情况下，emoji包可能有助于找到他们所有。
