Why is the "sail up" command not building my laravel docker containers?

I'm trying out Laravel Sail, as I've been successfully using Laradock for a few years and hoping to simplify my dev environment setup. I am on Windows 10 64, Docker Desktop 3.0 installed using WSL 2, and my Laravel app is running Laravel 8.20.1.

In my Laravel project, I've followed the Laravel Sail setup guide: I've run composer require laravel/sail --dev and php artisan sail:install, and I see the docker-compose.yml in my root directory.

But when I run ./vendor/bin/sail up I get this error:

./vendor/bin/sail: line 1: XSym: command not found
./vendor/bin/sail: line 2: 0024: command not found
./vendor/bin/sail: line 3: a81960381c7144e16cd1e768af147de3: command not found
./vendor/bin/sail: line 4: ../laravel/sail/bin/sail: No such file or directory

Update: I fixed the above through Qumber's help: removing /vendor/ and reinstalling. But now I get this error:

In GitBash I get this response:

Unsupported operating system [MINGW64_NT-10.0-19041]. Laravel Sail supports macOS, Linux, and Windows (WSL2).

If I try from Powershell now, I get:

/bin/bash: C:\Users\ssund\Source\steepdb\vendor\bin\/../laravel/sail/bin/sail: No such file or directory

Solution

Ok there were multiple things that I needed to fix here.

@Qumber helped me initially by suggesting I wipe /vendor/ and run composer install/update again. That fixed the missing sail file that wasn't getting added for some reason.
I also had some permission-related issues, possibly due to running compose in WSL and then trying to run sail in Windows/GitBash (or vice versa).
The biggest issue was my misunderstanding about Docker WSL2 integration and that the sail command should be run from within WLS (coming from Laradock, I made some incorrect assumptions). I needed to have a linux distro installed (I chose Ubuntu 20.x) AND make sure it was set as the default, via running wsl -s . You can check which is currently default with wsl -l -v. For more detailed steps about this setup see https://learn.microsoft.com/en-us/windows/wsl/install-win10#step-4---download-the-linux-kernel-update-package.

Once I fixed the above, I was able to open Windows Terminal, create an Ubuntu tab, and run ./vendor/bin/sail up and it executed.
