Is script able to exec different commands on different platforms?

[monchin]

Hello, my scenes is, I use nuitka to package my project, and I have a script dist = "pdm run python -m nuitka --standalone main.py. In order to ensure that I could use correct dependent packages, I want to clear cache and re-sync, and it seems that pre_dist would be appropriate. pre_dist should be

pre_dist = { composite = [
    "pdm cache clear",
    "rm -r .venv/lib" for linux and "rmdir /s /q .venv\\Lib" for windows,
    "pdm sync"
] }

So the issue is the second step, commands to recursively deleting a directory are different on linux and windows. There are two issues here

1. On windows, a PdmUsageError would be raised saying "Command 'rmdir' is not found in your Path.". I read the code and found in pdm, the script command must be in env var. But it seems that rmdir is not in env var. Linux rm is OK because it is in /usr/bin
2. Is there a way to add conditions like pip install/pdm add sys_platform == "win32"

No, make a custom script instead.

FWIW, to achieve what you want, you can use pdm venv create -f to replace the rm command

I tried pdm venv create -f and found that on windows, but it says

77 files are removed
[FileNotFoundError]: [WinError 2] 系统找不到指定的文件。(System can't find specified files)
WARNING: Add '-v' to see the detailed traceback

linux raises simillar error [FileNotFoundError]: [Errno 2] No such file or directory: '/home/mon/Projects/test/pdm_test/.venv/bin/python'

I can't reproduce, what is your setup? How to reproduce it from a clean environment?

only pdm venv create -f would be Okay, I mean use pdm venv create -f to replace the rm command like

pre_dist = { composite = [
    "pdm cache clear",
    "pdm venv create -f",
    "pdm sync"
] }

In this way FileNotFoundError would be raised

[frostming]

pdm init -n
pdm venv create -f

Can't reproduce

Will pdm init -n or pdm venv create -f clear pdm caches？I need to clear caches before.

My pyproject.toml is

[project]
name = "pdm_test"
version = "0.1.0"
description = "Default template for PDM package"
authors = [
    {name = "mon", email = "[email protected]"},
]
dependencies = [
    "python-dotenv>=1.0.1",
    "numpy<2.0.0",
]
requires-python = ">=3.10"
readme = "README.md"
license = {text = "MIT"}


[tool.pdm]
distribution = false

[tool.pdm.scripts]
pre_test = { composite = [
    "pdm cache clear",
    "pdm venv create -f",
    "pdm sync"
]}
test = "python main.py"

The permission error has nothing to do with the caches so clearing caches or not doesn't make difference
