Poethy安装失败，原因是EnvCommandError：查找版本2020.12.21.3lambda，为什么？

Question

诗歌不能完成任何{}或{}而不抛出一个{}与无法找到{}的{}有关

它寻找版本“2020.12.21.3-lambda”，我不明白为什么它没有像其他依赖项一样从远程源加载具有正常版本的依赖项

这个软件包已经运行了一段时间了。我不记得在pyproject.toml中更改了什么我试着检查一下pyproject.toml的旧版本，看看是否有什么意外的变化。同样的结果

我还尝试删除.venv/诗歌创建并重新创建它。同样的结果

我不知道soupsieve作为一种依赖关系将走向何方。它在诗歌创造的环境中使用朴素的老点子安装得恰到好处

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

Answer 1

快速修复

因此，根本问题与poetry无关，但我至少能够通过显式地添加具有特定版本的子依赖项来解除对此问题的阻碍

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坏元数据毒害的私有工件存储库代理所有东西：它包含名为soupsieve的东西，而实际上并不是soupsieve

一旦我们移除了这些东西，poetry又恢复了正常工作

Answer 2

我有同样的错误，因为出于某种原因poetry install总是无法在%APPDATA%中创建虚拟环境路径。解决方案是将venv移动到本地项目根目录

poetry config virtualenvs.in-project true
poetry env remove python
poetry install
