Thank you for filing! Check list:

• [x] Is it a bug? Usage questions should often be asked in the forum instead.
• [x] Concise, focused, friendly issue title & description.

Cannot compile the code. Compiler fails with the following error:

$ npx rescript
Dependency Finished
rescript: [1/3] src/Main.ast
FAILED: src/Main.ast
CreateProcess failed: The system cannot find the file specified.
FAILED: cannot make progress due to previous errors.

Cannot run in watch mode. Compiler fails with the same error.

Tried these options already with ReScript 11.0.0-rc.3 and 10.1.4 versions on Windows 10, Windows 11 and NixOS Unstable (at the time of writing 23.11) on the x86_64 platform:

• Deleting node_modules/ and package-lock.json all-together and re-installing dependencies.
• Deleting the project and re-creating it again.
• Creating the project on my NixOS machine (where the compiler works perfectly) and sending it to Windows 11.

The error occurs only on Windows 11 for unknown reasons and I don't even have the src/Main.ast file at all.

• [x] A minimal, reproducible example.

I'm not sure if I can capture the exact state of that machine and send it to you, so the only option is to try it out on any Windows 11. Here are relevant project/config files:

package.json:

{
	"name": "basics",
	"type": "module",
	"scripts": {
		"res:build": "rescript",
		"res:dev": "rescript build -w"
	},
	"dependencies": {
		"rescript": "^11.0.0-rc.3"
	}
}

bsconfig.json:

{
	"name": "basics",
	"sources": [
		{
			"dir": "src"
		}
	],
	"package-specs": [
		{
			"module": "es6",
			"in-source": true
		}
	],
	"suffix": ".bs.mjs",
	"bs-dependencies": []
}

src/Main.res:

Js.log("hello, world")

• [x] OS and browser versions, if relevant.

OS: Windows 11 x86_64.

• [ ] Is it already fixed in master? Instructions
