You have to load vendor/autoload.php, which will autoload that file for you:
您必须加载vendor/autoload.php，它会为您自动加载该文件：
require_once __DIR__ . '/vendor/autoload.php';
This is assuming that your file is located at the same directory level as the vendordirectory.
这是假设您的文件与目录位于同一目录级别vendor。
Otherwise, adjust.
否则，调整。

run composer install
跑 composer install
That will import your packages and create the vendor folder as well as the autoload script. Also, make sure your relative path is correct.
这将导入您的包并创建供应商文件夹以及自动加载脚本。另外，请确保您的相对路径是正确的。
