Symfony 2.8：ResourceInterface::isFresh() 自 2.8 起已弃用

Question

升级到 Symfony 到 2.8 后，发现很多 deprecation 警告：

“Symfony\Bundle\AsseticBundle\Config\AsseticResource”类是 通过 ResourceInterface::isFresh() 执行资源检查， 自 2.8 起已弃用，将在 3.0 中删除（54 次）

堆栈（来自 Symfony 分析器）

我用过的升级：

composer.phar update symfony/symfony --with-dependencies

这是我的 composer.json

}

如何解决这个弃用警告？

Answer 1

您是否尝试过将资产包版本更新到最新版本？

"symfony/assetic-bundle": "~2.7", 

Answer 2

一些谷歌搜索发现：https://knpuniversity.com/screencast/symfony3-upgrade/fix-deprecations-in-bundles

他们链接到 Assetic GitHub 页面，该页面声称 2.7.1 已为 Symfony 3 做好准备。但显然不是。就这么容易。 Assetic 只是没有为 symfony 3 做好准备，所以它在 2.8 中产生了很多弃用通知。 merge request to fix this 尚未合并。

Answer 3

dev-master 分支已经与 Symfony 3 兼容了几个星期了。更新使用没有错。

composer.json

....
"symfony/assetic-bundle": "dev-master",
....

composer 更新 symfony/assetic-bundle

所有错误都会消失。
