缺少脚本：bootstrap/app.php，在我安装作曲家之后

Question

我有一个现有的 laravel 项目并尝试运行它。

但是在我做了composer install之后。我收到此错误：

C:\xampp\htdocs\laravel>php 工匠 PHP 警告：require_once(C:\xampp\htdocs\laravel/bootstrap/app.php): 无法打开流：第 20 行的 C:\xampp\htdocs\laravel\artisan 中没有此类文件或目录

当然，我是先用谷歌搜索的。但我没有看到任何解决方案。

那么我必须改变什么？

谢谢

这是 composer.json 文件：

从here 下载 zip，然后从该 zip 中仅复制 bootstrap 文件夹并放入您的根目录

如我所见

 "psr-4": {
            "Intranet\\": "app/"
        }

注意：-因此，您从 laravel orignal zip 复制的每个文件都将命名空间从 app 更改为 Intranet
