The dependencies for your project are not installed. Just download composer from GetComposer.organd install it on your Windows Machine. Then navigate to your project root, you will see a composer.json file there. That file specifies all the dependencies of the project. Run composer update in that directory. Composer will then update or install all required dependencies and your application won't show the error then.
未安装项目的依赖项。只需从GetComposer.org下载 composer并将其安装在您的 Windows 机器上。然后导航到您的项目根目录，您将在那里看到一个 composer.json 文件。该文件指定了项目的所有依赖项。在该目录中运行 composer update 。然后 Composer 将更新或安装所有必需的依赖项，然后您的应用程序将不会显示错误。
cd \wamp\www\yourproject
composer update

I figured it out! I was missing a folder called "vendor" and a file inside bootstrap called "compiled.php" Sorry for the inconvenience, and thank you for trying!

"C:\wamp\www>composer create-project laravel/laravel laravel"
"[InvalidArgumentException] Project directory laravel/ is not empty."
"C:\wamp\www>composer create-project laravel/laravel laravel"
“[InvalidArgumentException] 项目目录 laravel/ 不为空。”
This means C:\wamp\www\laravelalready existed when you attempted to run the command. Remove the folder, or change the create-projectcommand to use a different folder name for your new project.
这意味着C:\wamp\www\laravel在您尝试运行命令时已经存在。删除文件夹，或更改create-project命令以对新项目使用不同的文件夹名称。
