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

Question

诗歌无法完成任何install 或add 而不抛出EnvCommandError 与无法为soupsieve 找到setup.py 有关。

它查找版本“2020.12.21.3-lambda”，但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运行良好。我不记得更改 pyproject.toml 中的任何内容。 我尝试检查pyproject.toml 的旧版本，看看是否可能发生意外更改。同样的结果。

我也尝试删除 .venv/ Poetry 创建并重新创建它。同样的结果。

我不知道 soupsieve 作为依赖项来自何处。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

快速修复

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 就会恢复正常工作。

Answer 2

我遇到了同样的错误，因为由于某种原因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
