Laravel PackageManifest.php: Undefined index: name

laravel 错误提示:In PackageManifest.php line 122: Undefined index: name

1、找到对应文件 :

vendor/laravel/framework/src/Illuminate/Foundation/PackageManifest.php

2、找到对应行

$packages = json_decode($this->files->get($path), true);

在这里新增两行代码

$installed = json_decode($this->files->get($path), true);
$packages = $installed['packages'] ?? $installed;
