python - 诗歌安装失败并出现 EnvCommandError：查找版本 2020.12.21.3-lambda，为什么？

问题描述

诗歌无法完成任何install或add没有EnvCommandError与无法找到一个setup.py有关的问题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。我不记得在pyproject.toml. 我尝试检查旧版本的pyproject.toml，看看是否可能发生了意外更改。结果相同。

我还尝试删除.venv/诗歌创建并重新创建它。结果相同。

我不知道soupsieve作为依赖项会在哪里出现。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

解决方案

快速解决

所以根本问题与 . 无关poetry，但我至少能够通过显式添加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毒化的私有工件存储库代理所有内容：它包含命名soupsieve为实际上不是soupsieve.

一旦我们删除了这些东西，poetry就可以恢复正常工作。
