找不到满足要求的版本pyyaml>=5.3，但是PyYAML是5.3.1版本

Question

我正在使用 SetupTools 构建 package of my own。在 setup.py 中的 INSTALL_REQUIRES 中，我有以下依赖项：

...
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，出现以下错误：

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)

但是，pip3 search pyyaml 告诉我 PyYAML 肯定存在：

PyYAML (5.3.1) - YAML parser and emitter for Python

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

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，我已经尝试了 PyYAML、pyyaml、5.3.1、5.3 等的所有组合，但是没有任何效果。我什至试图删除版本要求（所以 INSTALL_REQUIRES=['ray>=0.87','pyyaml']）但这会导致另一个错误：

Anthony Sottile 使用 --extra-index-url 的建议对我有用。

找不到满足要求的版本pyyaml>=5.3，但是PyYAML是5.3.1版本
