Cannot install barryvdh/laravel-dompdf - php

Question

I could not install barryvdh/laravel-dompdf using composer require barryvdh/laravel-dompdf.
The error I got was:
[Invalid argument exception] Could not find a matching version of barryvdh/laravel-dompdf. Check the package spelling, your version constraint and that the package is available in a stability which matches your minimum-stability (dev).
So in order to fix the error, I included barryvdh/laravel-dompdf: master#dev in composer.json and did a composer update. This time it gave me the error:
The requested package barryvdh/laravel-dompdf could not be found in any version. there may be a typo in the package name
Below is my composer.json:
{
"name": "laravel/laravel",
"description": "The Laravel Framework.",
"keywords": ["framework", "laravel"],
"license": "MIT",
"type": "project",
"require": {

},

What do you think I am missing here?

Answer 1

Usually, it is advisable not to edit composer.json directly when installing third-party packages. You can remove the line "barryvdh/laravel-dompdf": "master#dev" from your file, and run this command from your project root directory instead:
composer require barryvdh/laravel-dompdf
It installs the latest stable third-party package and automatically updates both composer.json and composer.lock files.
UPDATE: To solve the problem with your composer.jsonfile, change the repositories key to this:
"repositories" :
[
{
"type": "composer",
"url": "https://packagist.org"
},
{
"packagist": false
}
]

Answer 2

Use
"barryvdh/laravel-dompdf": "^0.8.4",
instead of
"barryvdh/laravel-dompdf": "master#dev"

Answer 3

The package got installed after removing the repositories section from my composer.json.
Thank you all for the help

Answer 4

Remove this line in your composer.json file
"require": {
"barryvdh/laravel-dompdf": "master#dev"
},
After, run this command in your command prompt
composer require barryvdh/laravel-dompdf
This will download the package and the dompdf + fontlib libraries also. This will generate the latest version for your project
