为什么我的作曲家依赖项没有在docker容器中找到但是本机在我的mac上？

Question

在我的php应用程序中，我有几个依赖项，通过composer安装。当我在我的mac机器上本地构建这个应用程序时，所有的PHP依赖项都正确安装。运行应用程序时，作者的自动加载器可以找到：名称空间，文件和类。

但是，我希望在docker容器中运行此应用程序，以便我可以将容器推送到ECS。当我在容器内运行相同的应用程序（在我的mac上本地工作）。 Composer的自动加载器无法找到某个类，而是抛出这样的异常：PHP Fatal error: Uncaught Error: Class ... not found in ...。

真正奇怪的部分是正确的命名空间显示在vendor/composer/autoload_psr4.php（没有丢失），并且类文件确实存在于docker容器中的vendor目录中。

我能找到的唯一解决方案（让作曲家找到类）是删除供应商的目录并在docker容器内重新运行composer install。但是我不想这样做。我应该能够将容器发布和部署到ECS，而无需在构建之后再次安装我的作曲家依赖项。我也尝试在入口点运行composer dump-autoloader，但这并没有解决我的问题。

有没有其他人遇到过这样的问题：php，composer和docker？

这是一些有用的文件：
