Php 创建Laravel项目时出错

使用

laravel new project

命令创建项目时出错。 项目已创建，但执行此操作时会输出错误。在完成项目的手工制作之后，您不能使用

php artisan serve

运行它

它在制作应用程序时输出的日志为：

我试图克隆

https://github.com/symfony/http-foundation.git

repo，使用

git-clone就可以很好地工作https://github.com/symfony/http-foundation.git

在同一终端上

我还试图在互联网上查找错误，但到目前为止没有任何帮助。我想为所有未来的项目解决这个问题，尤其是这个项目。

删除供应商目录，然后尝试

composer install

@Quezler您是指我创建的项目中的供应商文件夹还是项目文件夹中的另一个供应商文件夹（

C:\Users\manager\Desktop\project\ventor

）@但这意味着我每次创建新项目时都要这么做，对吗？我正在寻找一个更“确定的解决方案”：\从我所看到的这是一个一次性问题，供应商文件夹中已经存在一个symfony包，因此请尝试上述方法，并让我知道是否失败或成功，而此代码可能会回答问题，提供关于此代码为什么和/或如何回答此问题的附加上下文可提高其长期价值。

php artisan config:cache
composer update
