Laravel PackageManifest.php: Undefined index: name
Solution 1:
Try this, it worked for me, in the following file:
vendor/laravel/framework/src/Illuminate/Foundation/PackageManifest.php
Find this line and comment it:
$packages = json_decode($this->files->get($path), true);
Add two new lines after the above commented line:
$installed = json_decode($this->files->get($path), true);
$packages = $installed['packages'] ?? $installed;
Solution 2:
I had the same problem, I just execute the command:
composer update
this will updated the composer.lock file. After that worked like a charm.
