PyPi 拒绝版本值

Question

我正在尝试将包上传到 pypi 并出现错误：

'4.5.1-2021.2-0' is an invalid value for Version. Error: Start and end with a letter or numeral containing only ASCII numeric and '.', '_' and '-'. See https://packaging.python.org/specifications/core-metadata for more information.

我知道我的名字不符合 PEP440 标准，但它符合 PyPi 值格式。奇怪，它将 _ 替换为 -

来自setup.py：

setuptools.setup(
    name="opencv-python-inference-engine",
    version="4.5.1_2021.2_0",
...

包文件名：opencv_python_inference_engine-4.5.1_2021.2_0-py3-none-manylinux1_x86_64.whl

除了 PRP440 合规性，我做错了什么？

UPD: '4.5.1-2021.2' 也会产生错误，但它看起来符合 PEP440（预发布分隔符）。

Answer 1

您的版本不符合 PEP440 标准。预发行版本必须包括预发行“阶段”（alpha、beta、候选发布版）。

The pre-release segment consists of an alphabetical identifier for the pre-release phase, along with a non-negative integer value. Pre-releases for a given release are ordered first by phase (alpha, beta, release candidate) and then by the numerical component within that phase.

X.YaN   # Alpha release
X.YbN   # Beta release
X.YrcN  # Release Candidate
X.Y     # Final release

对于 alpha，这意味着字母 a，对于 beta，这意味着字母 b，对于 Release Candidate，您需要 rc。将破折号更改为 a 或 b，我认为它会起作用。
