Question

我正在尝试将我的项目从2.7更新到3.0

我已从https://github.com/symfony/symfony-standard/blob/v3.0.0/composer.json更新了composer.json，并添加了我在项目中使用的扩展程序

composer.json

我在更新时遇到下一个错误

这是解决方案吗？

Answer 1

还有一些其他的东西要在composer.json文件的基础上更新。关于控制台，即返回错误的文件，您需要替换

require_once __DIR__.'/../bootstrap.php.cache';

通过

require __DIR__.'/../app/autoload.php';

在app / AppKernel.php和其他文件中有更重要的更改。更多信息：

Answer 2

使用这些命令可以解决您的问题：

rm -rf var/cache/*

rm -rf var/logs/*

然后清除缓存产品和开发。

因为有时在升级或使用composer update时，缓存可能会保留旧引用并使清除缓存变得困难。
