python - 诗歌安装失败，EnvCommandError : looks for version 2020. 12.21.3-lambda，为什么？

Question

诗歌无法完成任何install或 add不扔EnvCommandError与找不到 setup.py 有关对于 soupsieve .
它查找版本“2020.12.21.3-lambda”，我不明白为什么它不像其他依赖项那样从具有正常版本的远程源加载依赖项。

这个包在一段时间内工作得很好。我不记得更改 pyproject.toml 中的任何内容. 我尝试查看 pyproject.toml 的旧版本看看是否有什么意外发生了变化。 结果相同。
我还尝试删除 .venv/诗歌创造和再创造它。 结果相同。
我不知道在哪里 soupsieve是作为一个依赖来的。它在诗歌创建的环境中使用普通的旧 pip 安装得很好。

cd project/
poetry shell
pip install soupsieve # Installs 2.1 without a problem

Answer 1

快速解决
所以根本问题与 poetry 无关，但我至少能够通过显式添加具有特定版本的子依赖项来解除对这个问题的阻碍。

pip add soupsieve==2.1

根本问题
真正的问题是我们的系统通过一个被错误元数据污染的私有(private)工件存储库代理所有内容:它包含名为 soupsieve 的东西。实际上不是 soupsieve .
一旦我们删除了这些东西， poetry恢复正常工作。
