如何在 pyproject.toml 文件中配置特定于操作系统的依赖项 [Maturin]

Question

I have a rust and python project that I am building using Maturin( https://github.com/PyO3/maturin ). It says that it requires a pyproject.toml file for the python dependencies.

I have a dependency of uvloop , which is not supported on windows and arm devices. I have added the code that conditionally imports these packages. However, I do not know how to conditionally install these packages. Right now, these packages are getting installed by default on every OS.

Here is the pyproject.toml file.

[project]
name = "robyn"
dependencies = [
  "watchdog>=2.1.3,<3",
  "uvloop>=0.16.0,<0.16.1",
  "multiprocess>=0.70.12.2,<0.70.12.3"
]

And the github link, jic anyone is interested: https://github.com/sansyrox/robyn/pull/94/files#diff-50c86b7ed8ac2cf95bd48334961bf0530cdc77b5a56f852c5c61b89d735fd711R21

If you don't want to install on windows, specify like this:

# assuming you're using poetry
uvloop = {version = "^0.16.0", markers = 'sys_platform != "win32"'}
