Not saying this is work for you, but those are steps that usually fix Laravel, when the problem is not on your source code, of course:
并不是说这对你有用，但这些是通常修复 Laravel 的步骤，当然，当问题不在你的源代码上时：
cd /your/application/dir
rm bootstrap/compiled.php
rm -rf vendor
composer install --no-dev

Yes, it can work as @oli-folkerd 's answer. However, as seen in Laracasts (Laravel 5 Fundamentals series Video 10 "forms" min 16:55), almost in top of your ControllerClass php file, just add the following (or import the class if your php editor allows you do so):
是的，它可以作为@oli-folkerd 的答案。然而，正如在 Laracasts（Laravel 5 Fundamentals series Video 10 "forms" min 16:55）中所见，几乎在您的 ControllerClass php 文件的顶部，只需添加以下内容（如果您的 php 编辑器允许，则导入该类）：
use Carbon\Carbon;
Now you can simply use Carbon
现在你可以简单地使用 Carbon
$input['published_at'] = Carbon::now();
without having to add Carbon\
无需添加 Carbon\
回答by Oli Folkerd
you need to add the line:
您需要添加以下行：
'Carbon' => 'Carbon\Carbon',
to the bottom of the 'aliases'array in app/config/app.php this will make the carbon library available everywhere in laravel.
到'aliases'app/config/app.php 中数组的底部，这将使碳库在 Laravel 中随处可用。

Some times specifying prefer-distprefixed by “--” (aka “bare double dash”) at the end or suffixing at the end of create-projectalso matters while installing...
有时在最后指定prefer-dist前缀“--”（又名“裸双破折号”）或在最后指定后缀在create-project安装时也很重要...
The below command was working fine in laravel 5.5without getting an error

composer create-project laravel/laravel blog --prefer-dist

Whoops\Exception\ErrorException : Class 'Carbon\Carbon' 未找到
After referring to the official Installation Documentation
