Answer 1

Hello,

Try this, it is worked for me, in 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 above commented line

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

Yes, It worked for me. 

Senario: I have Downloaded a codebase from another computer, and tried to setup in my laptop. There I found project has laravel 5.8 version, so I upgraded it to 6.0.4.

Steps:-

1. Upgraded Composer.json

"license": "MIT",
    "require": {
        "php": "^7.1.3",
        "fideloper/proxy": "^4.0",
        "laravel/framework": "5.8.*",
        "laravel/tinker": "^1.0"
    },

===>>>

"license": "MIT",
    "require": {
        "php": "^7.1.3",
        "fideloper/proxy": "^4.0",
        "laravel/framework": "6.0.*",
        "laravel/tinker": "^1.0"
    },

2.  Run "Composer update" in bash

~~~~~ Then I got the error

Solution: 

1. Removed "composer.lock" from root => not worked

2.  added bellow lines in  "PackageManifest.php" after " $packages = json_decode($this->files->get($path), true);" => now the issue is resolved.

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