2. Add this to the pyproject.toml:

Expected Result

Same as running npm --version: 10.2.0 on my machine.

Actual Result

On linux it works fine though.

I did a bit of digging and found that the output of shutil.which changes when run through rye:

> where npm
C:\Program Files\nodejs\npm
C:\Program Files\nodejs\npm.cmd

> py -c "import shutil; print(shutil.which('npm'))"
C:\Program Files\nodejs\npm

> rye run print-npm-path
C:\Program Files\nodejs\npm.CMD

But oddly, the PATH doesn't change, except for the addition of .venv\Scripts:

> echo %PATH%

More info: The output of where is unaffected when run through rye:

> rye run where
C:\Program Files\nodejs\npm
C:\Program Files\nodejs\npm.cmd

So apparently the problem is that there is no npm.exe. Turns out that npm is a shell script, so I can execute it in my cygwin terminal, and npm.cmd does the same for cmd.exe/powershell. But since there is no npm.exe, something like subprocess.run('npm') (and whatever the equivalent of that in rust is) fails.

That said, adding shell=True would fix this problem. Is there any way to make a rye script do that? Currently my script is defined like so:

[tool.rye.scripts]
build = "npm run build"
