在 pyproject.toml 中使用带有孵化后端的直接引用

Question

如果我正确理解孵化的文档，在pyproject.toml以孵化作为后端的情况下，我应该能够使用本地直接引用模式在包文件夹中添加本地包<NAME> @ {root:uri}/pkg_inside_project。

\n

这是一个最小的非工作示例，在包中，我将依赖项添加到名为viastackoverflow_demo的包中。my_local_packagemy_local_package @ {root:uri}/my_local_package

\n

当我克隆存储库，进入文件夹并尝试stackoverflow_demo通过运行安装时pip install -e .，我收到一个很长的错误（见下文）。

\n

如何正确使用本地包直接引用？

\n
• 我正在使用-epip 标志，因为我希望能够以可编辑模式安装它。应该支持可编辑和正常两种模式。目前，它在任何一种模式下都不起作用，并且错误（几乎）相同。
\n
• 我使用的是pip22.2.2版本
\n
• 不幸的是，我只能使用pip安装，没有其他包管理器。
\n
• 我无法从某些远程 git 存储库等安装本地包。

从问题跟踪器我收到了答案，我只需将以下两行添加到pyproject.toml. 请参阅文档。

[tool.hatch.metadata]
allow-direct-references = true
