Installation failed, reverting ./composer.json to its original content.

I use this guideline for the installation. https://jetstream.laravel.com/1.x/installation.html

I tried to delete the vendor and run composer update doesn’t work tried to cache clear but still doesn’t work.

Answer

Uncache your routes and try again.

---

1. Remove jetstream from composer

   composer remove laravel/jetstream
   

2. Then you should be able to cache your routes using

    php artisan route:cache
   

3. Then install jetstream

    composer require laravel/jetstream
