I tried to run this "composer require mckenziearts/laravel-notify" in my laravel 6 project but I get this error - composer-php

Question

Problem 1
- Root composer.json requires laravel/tinker ^2.0, found laravel/tinker[v2.0.0, ..., 2.x-dev] but the package is fixed to v1.0.10 (lock file version) by
a partial update and that version does not match. Make sure you list it as an argument for the update command.
Problem 2
- mckenziearts/laravel-notify 2.x-dev requires illuminate/support ~7.0 -> found illuminate/support[v7.0.0, ..., 7.x-dev] but these were not loaded, likely because it conflicts with another require.
- mckenziearts/laravel-notify v2.1 requires illuminate/support ^7.0|^8.0 -> found illuminate/support[v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev] but these were not loaded, likely because it conflicts with another require.
- Root composer.json requires mckenziearts/laravel-notify ^2.1 -> satisfiable by mckenziearts/laravel-notify[v2.1, 2.x-dev].
Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
Installation failed, reverting ./composer.json and ./composer.lock to their original content.
This is the composer.json file. laravel 6.
I think there's an update for me to do but I don't know where to do that.

Answer 1

You are using Laravel v6 and try to install mckenziearts/laravel-notify in the most recent version, which is only compatible with Laravel v7 and v8.
You should either upgrade Laravel, or install mckenziearts/laravel-notify in v1 through composer require mckenziearts/laravel-notify "^1.0"
