找不到满足 html-form-to-dict 要求的版本（来自版本：none）
Could not find a version that satisfies the requirement html-form-to-dict (from versions: none)
我刚刚将我的库移植到 Python 2.7
通过 pip install -e git+ssh://git@github.com/guettli/html_form_to_dict#egg=html_form_to_dict 安装适用于 Python 2.7.
但是如果我通过pip安装它会失败：
pip install -v html-form-to-dict
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.

我能做些什么，让它可以安装到 Python 2.7？
顺便说一句，我在 setup.cfg 中使用了这个（所以这不是问题所在）：
[options]
python_requires = >=2.7
我找到了答案。
如果您的版本转到“下载文件”，那么您可以看到哪些文件可用。
对我来说是这样的：https://pypi.org/project/html-form-to-dict/2022.3.1/#files
只有html_form_to_dict-2022.3.1-py3-none-any.whl
由于py3在这个文件名中，py2似乎无法安装它。
通过 twine 上传 tar.gz 后它起作用了：
python -m twine upload dist/html_form_to_dict-2022.3.2.tar.gz
更好的解决方案是构建一个万向轮，这样 py2 用户也可以从 .whl 安装而不是回退到 .tar.gz 版本。
为此，请在您的设置调用中添加：
# in setup.py
from setuptools import setup
setup(
...
options={"bdist_wheel": {"universal": True}},
)
现在您的 wheel 文件将被命名为 html_form_to_dict-2022.3.1-py2.py3-none-any.whl，Python 2.7 用户也可以使用它。如果需要，您仍然可以同时上传 sdist (.tar.gz)。
