The Mix manifest does not exist

• Laravel Mix Version: 1.6.2
• Node Version : 8.4.0
• NPM Version : 5.3.0
• OS: Ubuntu 16
• Laravel version : 5.4

Description:

I’m trying to install Laravel in a sub-directory, keeping security in mind, my directory structure is as follows

/var/www/laravel/
/var/www/html/demo/

(demo folder is where i prefer to be called as public folder. and things works like a charm except this mix issue.)

After i run npm run dev it creates mix-manifest.json in /var/www/html/demo/ directory along with css and js directories with compiled files.

in my views/auth/layout.blade.php , i have called the versioned asset like this.

<link href="{{ mix('/css/app.css') }}" rel="stylesheet">

And when i reload the page, it says

The Mix manifest does not exist.
in helpers.php (line 548)
at mix('/css/app.css')

in my /var/www/html/demo/ folder, the manifest exists.

{
    "/js/app.js": "/js/app.js?id=62141ada8b6feb788550",
    "/css/app.css": "/css/app.css?id=26d13f158c3bade2b2d3",
}

and here is my webpack.mix.js file contents

let mix = require('laravel-mix');
let path = require('path');
mix.setPublicPath(`..${path.sep}html/demo/`);
mix.js('resources/assets/js/app.js', 'js')
	.sass('resources/assets/sass/app.scss', 'css').version();

• I can call the css file directly, (<link href="{{ asset('css/app.css') }}" rel="stylesheet">). It works, but i prefer to call with mix versioning.
• I can call the css file <link href="{{ asset('css/app.css') }}" rel="stylesheet">. It works too. But not with mix.
• I have tried settings the mix.setResourceRoot('../html/demo/'); and it didnt help.
• I have tried https://stackoverflow.com/a/45154015 but it doesn’t help either (<link rel="stylesheet" href="{{ mix('css/app.css', '../html/demo') }}">)

Steps To Reproduce:

Install Laravel outside root. (/var/www/laravel) Assume example.com as the server. Create sub directory as example.com/demo/ (/var/www/html/demo) Move Files in /var/www/laravel/public folder to /var/www/html/demo

Change paths in demo/index.php

require __DIR__.'../../../laravel/bootstrap/autoload.php';
$app = require_once __DIR__.'../../../laravel/bootstrap/app.php';

Install packages with npm "laravel-mix": "^1.6.2"

Webpack.mix.js content.

let path = require('path');
mix.setPublicPath(`..${path.sep}html/demo/`);
mix.js('resources/assets/js/app.js', 'js')
	.sass('resources/assets/sass/app.scss', 'css').version();	

run npm dev

It should compile files into /var/www/html/demo folder and create mix-manifest.json file with above mentioned content.

Access example.com/demo/

It should produce the error.

Please help fix this. Thank you!

I solved in windows with:

Install php 7 e update older path that point older version

unistall e re-install node.js (not last 9 version that seem have a bug with npm)

Fresh laravel installation 5.5

Php artisan preset react (just this by cli)

Npm install Npm run dev

Now i can compile e use react in my laravel

Even with the package being auto discovered you need still to run. php artisan vendor:publish --provider="Laravel\Horizon\HorizonServiceProvider" Then re-run yarn dev or npm run dev
