使用python setup.py报错：Upload failed (403) / Upload failed (400)

当前报错的环境

• Python 3.9.19
• twine==1.15.0

本地~/.pypirc已正确配置了用户名和密码，用在pypi.org注册：

[pypi]
  username = skylerhu
  password = ${password}

执行 python setup.py sdist upload -r pypi 打包上传到仓库报错。

在不久之前同样的环境，执行是成功过的。

错误1

执行 python setup.py sdist upload -r pypi

Submitting dist/py-enum-1.1.0.tar.gz to https://upload.pypi.org/legacy/
Upload failed (403): Username/Password authentication is no longer supported. Migrate to API Tokens or Trusted Publishers instead. See https://pypi.org/help/#apitoken and https://pypi.org/help/#trusted-publishers

提示用户名、密码的鉴权方式已经不在支持，说是需要创建API Tokens上传包。

根据提示，到用户管理页面 https://pypi.org/manage/account/ 找到配置，按照提示新增了API token.

需要注意的是创建Token后记得复制保存Token值，一般都是以pypi-开头，复制值后按照提示配置本机.pypirc如下所示，其中__token__是固定写死的：

[pypi]
  username = __token__
  password = pypi-xxxx

错误2

再次执行报错：

Upload failed (400): Invalid value for blake2_256_digest. Error: Use a valid, hex-encoded, BLAKE2 message digest.

原因是distutils (python setup.py工具)已弃用，不应再使用，请使用twine将软件上传到 PyPI。

错误3

改用twine执行 twine upload -r pypi dist/py-enum-xxx.tar.gz 还是报错：

查找一些资料后，通过pip install -U twine 解决。

执行成功的版本是：twine==5.0.0

解决以上所有错误后，终于成功将包上传到了仓库。
