Laravel 8：安装失败，正在恢复。/composer.json 到其原始内容

Question

I'm using Laravel 8, and I want to install Laravel Collective v5.7.

So at the Terminal I said:

composer require "laravelcollective/html":"5.7.1"

But it returns this error:

Your requirements could not be resolved to an installable set of packages.

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

So what's going wrong? How can I install that version of Laravel Collective properly?

Answer 1

This is the crucial information:

laravelcollective/html v5.7.1 requires illuminate/view 5.7.*

v5.7 of that package requires Laravel 5.7, but your are using Laravel v8.

All versions since v6.2 are compatible with Laravel v8.
