Question

我尝试安装包HTML

python -m pip install HTML

Collecting HTML
  Using cached html-1.16.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "C:\Users\836D~1\AppData\Local\Temp\pip-build-xorbgx2e\HTML\setup.py", line 12, in <module>
        long_description = __doc__.decode('utf8'),
    AttributeError: 'str' object has no attribute 'decode'

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\836D~1\AppData\Local\Temp\pip-build-xorbgx2e\HTML\

关于这个主题有很多问题AttributeError：'str'对象没有属性'decode'，但是所有这些都是代码如何通过安装来修复探针？

将 html 添加到我的诗歌依赖文件然后运行 poetry install 时，我遇到了同样的问题：

Installing html (1.16): Failed

  EnvCommandError

同样，尝试使用 pip 安装 html 并得到 ModuleNotFoundError 错误：

ERROR: Command errored out with exit status 1:
     command: /usr/bin/python -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'/tmp/pip-install-p5pkr50r/html/setup.py'"'"'; __file__='"'"'/tmp/pip-install-p5pkr50r/html/setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' egg_info --egg-base /tmp/pip-install-p5pkr50r/html/pip-egg-info

然后我意识到，我不需要在 Python 3 中显式安装 html。它已包含在内。

此代码默认对我有效：

import html

print(html.unescape("Hello&lt"))  # prints 'Hello<'

安装HTML：AttributeError：'str'对象没有属性'decode'
