Composer update says nothing to install or update

Question

• Laravel Version: 5.6.35
• PHP Version: 7.1.20
• Database Driver & Version: MySQL v5.5.61-0ubuntu0.14.04.1

Description:

At the time of this question, the latest version of Laravel is 5.6.37 - released 2 days ago ie, 2nd September, 2018.

I already have a project that I am working on. On running composer update , I always get the following:

Loading composer repositories with package information
Updating dependencies (including require-dev)
Nothing to install or update
Generating optimized autoload files
> Illuminate\Foundation\ComposerScripts::postAutoloadDump
> @php artisan package:discover
Discovered Package: fideloper/proxy
Discovered Package: laravel/tinker
Discovered Package: barryvdh/laravel-debugbar
Discovered Package: nunomaduro/collision
Package manifest generated successfully.

This started only after I updated my laravel project to 5.6.35.

This is not the case when I install a new laravel project. On new installation, the latest version of laravel, ie, 5.6.37 gets downloaded.

Below is my composer.json file

        "optimize-autoloader": true
    },
    "minimum-stability": "dev",
    "prefer-stable": true
}

Steps To Reproduce:

1. Have a Laravel project <= 5.6.35
2. Run composer update

I don't know where and what should be the mistake that I must have committed.

I have tried the following

1. Running composer dump-autoload && composer update
2. Deleting composer.lock file and vendor directory. Then running composer update

But couldn't get my project updated to Laravel version 5.6.37

Answer 1

删除vendor文件夹并运行composer install为我做到了。

Answer 2

If deleting vendor and running composer install doesn't work, it might be a user-related issue. I was running composer install as the wrong user, and I got the same message. Running it as root fixed it.
