[SOLVED] UnexpectedValueException Could not parse version constraint when trying to instal laravelcollective

UnexpectedValueException Could not parse version constraint when trying to instal laravelcollective

I am new to Laravel and I am trying to install laravelcollective. I am just following the documentation [here][1] and I am using this from my project directory:

composer require "laravelcollective/html":"^5.4.0"

Unfortunately, immediately after I press enter I get the following error :

[UnexpectedValueException] Could not parse version constraint :5.4.0: Invalid version string ":5.4.0"

I just don't know how to troubleshoot this. I didn't find much on Google and this combined with my lack of experience with Laravel leaves me stuck.

Can someone help? [1]: https://laravelcollective.com/docs/5.4/html

Solution

You can add it manually in composer.json then use composer update.

Just add "laravelcollective/html": "5.4.*", under the row with "laravel/framework":"5.4.*",

Like this :

"require": {
        "php": ">=7.0.0",
        "fideloper/proxy": "~3.3",
        "laravel/framework": "5.4.*",
        "laravelcollective/html": "5.4.*", <-- Add this row
        "laravel/tinker": "~1.0"
    },
