在 MacBook Pro 上使用 docker 的 Composer DNS 问题

Question

我遇到了一些问题运行我的 docker 在装有 macOS Montery 12.3.1 的 M1 Macbook 上的应用程序。

我第一次启动容器时，安装所有包都没有问题。

然而，当我再次尝试用 composer.lock 构建它时，我收到以下错误：

我已经尝试了一些我在这里看到的解决方案，比如将 DNS 添加到 Docker 配置（这对我不起作用，仍然有同样的问题）：

这是我的Docker文件以获取更多信息：

Answer 1

看起来您使用的是相当过时的 Symfony Flex 版本。几天后，他们的服务器 flex.symfony.com 不再可用。这是 announced some months ago，将软件包 symfony/flex 更新到任何更新的版本（2021 年 10 月发布的 v1.17 之后的任何版本）应该可以解决问题。
