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;
