Unable to locate Mix fileのエラーが解決できない

お手上げ状態のため、どうかご教授ください。
Vuerouterを試して見たくて色々いじっていたらハマってしまいました。
このエラーがどうしても解決できません。
Unable to locate Mix file: /css/app.css. (View: /work/resources/views/welcome.blade.php)
locate Mix関係でインストールもれや記述がないものがあるのでしょうか？

$ npm installでインストールした後に、package.jsonを以下のようにいじりました。
package.json

package.json
1    "private": true,
2    "scripts": {
3        "dev": "npm run development",
4        "development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
5        "watch": "npm run development -- --watch",
6        "watch-poll": "npm run watch -- --watch-poll",
7        "hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
8        "prod": "npm run production",
9        "production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
10    },
11    "devDependencies": {
12        "axios": "^0.18",
13        "browser-sync": "^2.26.3",
14        "browser-sync-webpack-plugin": "2.0.1",
15        "cross-env": "^5.1",
16        "laravel-mix": "^4.0.7",
17        "resolve-url-loader": "^2.3.1",
18        "sass": "^1.15.2",
19        "sass-loader": "^7.1.0",
20        "vue": "^2.5.17",
21        "vue-router": "^2.8.1",
22        "vue-template-compiler": "^2.5.21"
23    }
24}

その後、welcome.blade.php、HelloWorldComponent.vueを用意しました。
ここのmix('css/app.css')で怒られているようです。

/src/resources/views/welcome.blade.php

<!doctype html>
<html lang="{{ app()->getLocale() }}">
    <head>
        <meta charset="utf-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <meta name="viewport" content="width=device-width, initial-scale=1">

        <title>Laravel</title>
        
        <link href="{{ mix('css/app.css') }}" rel="stylesheet" type="text/css">
    </head>
    <body>
        <div id="app">
            <example-component></example-component>
        </div>
    <script src="{{ mix('js/app.js') }}"></script>
    </body>
</html>

/src/resources/assets/js/components/HelloWorldComponent.vue

<template>
    <div class="container">
        <div class="row">
                Hello World!
        </div>
    </div>
</template>

<script>
    export default {
        mounted() {
            console.log('Component mounted.')
        }
    }
</script>

お手数お掛け致しますが、どなたかご教授のほどよろしくお願いいたします。
