Question

此刻我与laravel取得了联系。我试图创建一个扫描qr代码的页面。

我用laravel（composer create-project laravel / laravel testqrinstascan）创建了一个普通的项目，并尝试逐步实施instascan。

我想使用这个库instascan - ＆gt; https://github.com/schmich/instascan

但我每次都会收到错误“Ladenfehlgeschlagenfürdasmit der Quelle”http://localhost:8000/instascan.min.js“。”

但该文件位于同一目录

这意味着用源代码加载脚本....不可能 - ＆gt; https://imgur.com/a/SKang

这是我的welcome.blade.php --------------------------------------- ---------------------------------
