UnexpectedValueException Unable to parse version constraint while trying to set laravelcollective

Question

I am new to laravel and trying to install laravelcollective. I just follow the documentation here and I use this from my project directory:

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

Unfortunately, right after pressing ente I get the following error:

[UnexpectedValueException] Failed to parse version limit: 5.4.0: invalid version string ": 5.4.0"

I just don’t know how to solve this problem. I have not found much on Google, and this, combined with my lack of experience with Laravel, leaves me at a standstill.

Can anyone help?
