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

Question

升级Symfony到2.8后，发现了很多弃用警告：

The class "Symfony\Bundle\AsseticBundle\Config\AsseticResource" is performing resource checking through ResourceInterface::isFresh(), which is deprecated since 2.8 and will be removed in 3.0 (54 times)

升级我用过：

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 assetic bundle 版本更新到最新版本？

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

Answer 2

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

他们 link 转到 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。就这么简单。 Assetic 还没有为 symfony 3 做好准备，因此它在 2.8 中生成了很多弃用通知。 merge request to fix this 尚未合并。

Answer 3

dev-master 分支已经与 Symfony 3 兼容几周了。更新使用没问题

composer.json

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

作曲家更新symfony/assetic-bundle

所有错误都会消失。
