升级到Laravel 7时出现日期错误 [英] Error with date when upgrading to Laravel 7

问题描述

我已成功将Laravel实例升级到版本7.到目前为止，除以下错误外，一切似乎还不错.

I have successfully upgraded my Laravel instance to version 7. So far everything seems fine apart from the following error.

传递给Carbon \ CarbonInterval :: setLocalTranslator()的参数1必须 实现接口Symfony \ Component \ Translation \ TranslatorInterface， 给定的Carbon \ Translator实例，在 /var/www/laravel/vendor/nesbot/carbon/src/Carbon/Traits/Difference.php

Argument 1 passed to Carbon\CarbonInterval::setLocalTranslator() must implement interface Symfony\Component\Translation\TranslatorInterface, instance of Carbon\Translator given, called in /var/www/laravel/vendor/nesbot/carbon/src/Carbon/Traits/Difference.php

我已经遵循了升级文档，并在我的模型中添加了以下内容(但仍然存在相同的问题).

I have followed the upgrade documentation and have added the following to my models (but still having the same problem).

protected function serializeDate(DateTimeInterface $date)
{
    return $date->format('Y-m-d H:i:s');
}

推荐答案

找到了它……迁移似乎并不顺利.

Found it... The migration is not going well it seems.

SO修改composer.json以迁移到laravel 7和symfony 5. 然后删除供应商文件夹并重新安装所有内容

SO modify the composer.json to migrate to laravel 7 and symfony 5. Then remove vendor folder and reinstall everything

composer clearcache
composer install

然后它又可以工作了.
