无法找到满足需求pyyaml>=5.3的版本，但PyYAML是5.3.1版本

Question

我正在使用SetupTools构建一个我自己的包裹。在INSTALL_REQUIRES中的setup.py中，我有以下依赖关系：

...
INSTALL_REQUIRES = [
    'ray>=0.8.7',
    'pyyaml>=5.3',
]

setup(name=PACKAGE_NAME,
      version=VERSION,
      description=DESCRIPTION,
      long_description=LONG_DESCRIPTION,
      long_description_content_type=LONG_DESC_TYPE,
      author=AUTHOR,
      license=LICENSE,
      author_email=AUTHOR_EMAIL,
      url=URL,
      install_requires=INSTALL_REQUIRES,
      packages=find_packages()
      )

当我运行pip3 install -i https://test.pypi.org/simple/ r3po==0.0.6时，会得到以下错误：

ERROR: Could not find a version that satisfies the requirement pyyaml>=5.3 (from r3po==0.0.6) (from versions: 3.11)
ERROR: No matching distribution found for pyyaml>=5.3 (from r3po==0.0.6)

然而，pip3 search pyyaml向我展示了PyYAML确实存在：

PyYAML (5.3.1) - YAML parser and emitter for Python

pip3 install pyyaml (在安装了pyyaml的.venv中)

Requirement already satisfied: pyyaml in /home/lieu/dev/inzura-clustering-project/.venv/lib/python3.8/site-packages (5.3.1)

在你问之前--是的，我试过了PyYAML，pyyaml，5.3.1，5.3等等的所有组合，但是没有什么效果。我甚至试图删除版本要求(所以是INSTALL_REQUIRES=['ray>=0.87','pyyaml'])，但这会导致另一个错误：
