Question

安装Composer后，它运行良好，Laravel创建了所有文件夹，并正确启动：

php artisan serve

现在，当我尝试：

laravel new mypro

它不会创建vendor文件夹。当我尝试：

php artisan serve

它说：

php artisan serve
PHP Warning:  require(/mnt/PROJECTS/[3]_PROCOM/[6]_PHP_Learning/Laravel_1/blog4/bootstrap/../vendor/autoload.php): failed to open stream: No such file or directory in /mnt/PROJECTS/[3]_PROCOM/[6]_PHP_Learning/Laravel_1/blog4/bootstrap/autoload.php on line 17
PHP Fatal error:  require(): Failed opening required '/mnt/PROJECTS/[3]_PROCOM/[6]_PHP_Learning/Laravel_1/blog4/bootstrap/../vendor/autoload.php' (include_path='.:/usr/share/php') in /mnt/PROJECTS/[3]_PROCOM/[6]_PHP_Learning/Laravel_1/blog4/bootstrap/autoload.php on line 17

我复制文件夹供应商后说：

php artisan serve
PHP Fatal error:  Class 'Illuminate\Notifications\NotificationServiceProvider' not found in /mnt/PROJECTS/[3]_PROCOM/[6]_PHP_Learning/Laravel_1/blog3/vendor/laravel/framework/src/Illuminate/Foundation/ProviderRepository.php on line 146


  [Symfony\Component\Debug\Exception\FatalErrorException]                 
  Class 'Illuminate\Notifications\NotificationServiceProvider' not found

Answer 1

请运行命令

，而不是复制供应商文件夹

composer install

在laravel的项目目录中

Answer 2

尝试了来自不同来源的多种解决方案后，对我而言唯一有效的方法是升级PHP版本。

我遇到了同样的问题。发生这种情况是因为作曲家无法安装composer.json文件中指定的依赖项。尝试运行

如果这不能解决问题，请确保已安装以下PHP模块php-mbstring php-dom

要安装此扩展，请在终端中运行以下命令

composer install

一旦安装完成

尝试在项目根文件夹中再次运行命令

sudo apt-get install php-mbstring php-dom

因此，如果上述方法不起作用，您也可以尝试使用此命令

composer install
