{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Packaging fails when having venvs inside the sourctree","articleBody":"If virtual environment is installed inside the canopen code base (which is common practice), building the canopen package will fail. Setuptools seems to incorrectly disover the 3.8 venv as a pacakge and fails. See below. One could argue this is a corner-case, but I think the robustness of the package should be increased.\r\n\r\nThe root cause is that the `pyproject.toml` is not specifying the package it should install. \r\n\r\n```\r\nPS C:\\Work\\canopen-wip2\u003e .\\venv38\\Scripts\\python.exe -m pip install -e .                    \r\nObtaining file:///C:/Work/canopen-wip2\r\n  Installing build dependencies ... done\r\n  Checking if build backend supports build_editable ... done\r\n  Getting requirements to build editable ... error\r\n  error: subprocess-exited-with-error\r\n\r\n  × Getting requirements to build editable did not run successfully.\r\n  │ exit code: 1\r\n  ╰─\u003e [14 lines of output]\r\n      error: Multiple top-level packages discovered in a flat-layout: ['venv38', 'canopen'].\r\n\r\n      To avoid accidental inclusion of unwanted files or directories,\r\n      setuptools will not proceed with this build.\r\n\r\n      If you are trying to create a single distribution with multiple packages\r\n      on purpose, you should not rely on automatic discovery.\r\n      Instead, consider the following options:\r\n\r\n      1. set up custom discovery (`find` directive with `include` or `exclude`)\r\n      2. use a `src-layout`\r\n      3. explicitly set `py_modules` or `packages` with a list of names\r\n\r\n      To find more information, look for \"package discovery\" on setuptools docs.\r\n      [end of output]\r\n\r\n  note: This error originates from a subprocess, and is likely not a problem with pip.\r\nerror: subprocess-exited-with-error\r\n````","author":{"url":"https://github.com/sveinse","@type":"Person","name":"sveinse"},"datePublished":"2024-06-20T13:19:17.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/467/canopen/issues/467"}
