最新の Laravel 5.6.7 + PHP 7.1.15で Vueの環境を構築している際に、npm installが出来ずに半日程度費やした際の備忘録。Laravelそのものの問題ではないがこれが解決しないと Vue.jsの開発が出来ないので。

環境:

[root@localhost nginx]# php -v
PHP 7.1.15 (cli) (built: Feb 28 2018 14:06:54) ( NTS )

[root@localhost app]# php artisan –version
Laravel Framework 5.6.7

[root@localhost app]# npm –version
5.6.0

[root@localhost app]# node –version
v8.9.4

Laravel ドキュメントをみながら “npm install”を実行。途中から次のようなエラー（警告）が永久ループ…
“gyp WARN EACCES user “root” does not have permission to access the dev dir “/usr/share/nginx/app/node_modules/node-sass/.node-gyp/8.9.4”.

[root@localhost app]# npm install
npm WARN deprecated gulp-util@3.0.8: gulp-util is deprecated - replace it, following the guidelines at https://medium.com/gulpjs/gulp-util-ca3b1f9f9ac5

ここら を参考に何度か試してみると、いまく行った模様。

[root@localhost app]# rm -rf node_modules/
[root@localhost app]# npm install --unsafe-perm
[root@localhost app]# npm run dev
[root@localhost app]#

こちら を参考に vueのサンプルが動くように welcome.blade.phpを変更

[root@localhost app]# vi resources/views/welcome.blade.php

@extends('layouts.app')

@section('content')
    <example-component></example-component>
@endsection

http://192.168.33.10/ で確認、動いている模様。

ご参考までに😗
