试图加载类“WebProfilerBundle"来自命名空间“Symfony\Bundle\WebProfilerBundle"使用开发依赖项在 Heroku 上部署时 [英] Attempted to load class "WebProfilerBundle" from namespace "Symfony\Bundle\WebProfilerBundle" when deploying on Heroku using development dependencies
问题描述
我们在 Heroku 上托管了一个 Symfony 4.3 Web 应用程序.这是一个新设置，我们从未设法让开发模式正常工作.网上有很多类似的问题，但没有一个能解决我们在这里面临的确切症状.
We have a Symfony 4.3 web application hosted on Heroku. This is a new setup and we never managed to have the dev mode to work correctly. There are plenty of similar issues online but none fixes the exact symptoms we are facing here.
项目是用命令行创建的:
The project was created with a command line:
composer create-project symfony/website-skeleton appName
让我澄清一下:我们不想将从dev"改为prod"
Let me clarify that: we do not want to change from "dev" to "prod"
我们需要能够在开发模式下使用应用程序，以便根据 文章如何为 Symfony 4.3 自定义错误页面"
We need to be able to use the application in dev mode in order to take advantage of error debugging for PHP as per the article "How to Customize Error Pages" for Symfony 4.3 here

如果我们从 'dev' 环境更改为 'prod' 环境，应用程序可以工作，但我们无法以我们希望的方式看到错误.我们可以使用下面的命令(但这不是我们在这里试图解决的问题)来使用Symfony Var Dumper Server".我们不想使用这种方法.
If we change from 'dev' to 'prod' environment the application works but we cannot see the errors the way we wish to. We could use the command below (but this is not the point we are trying to solve here) in order to use "Symfony Var Dumper Server". We do not want to use this method.
./bin/console server:dump
似乎我们可能缺少一个依赖项，但是 composer update 和 composer install 和 composer dump-autoload 没有解决任何问题.
It seems that we might be missing a dependency but composer update and composer install and composer dump-autoload did not solve anything.
另请注意消息您是否忘记了另一个命名空间的使用"语句?在/tmp/build_a45354eb0ee7b20dd7ec870ed4fb1980/src/Kernel.php:23" - WebProfilerBundle 是否可能损坏在主存储库中?
Also note the message "Did you forget a "use" statement for another namespace? in /tmp/build_a45354eb0ee7b20dd7ec870ed4fb1980/src/Kernel.php:23" - Is it possible that the WebProfilerBundle is broken in the master repository?

我们目前不知道如何安装或验证捆绑包确实存在并且适用于 Symfony 4.3 - 这个方向的想法可能会有所帮助，但不仅如此.
We currently do not know how to install or verify that bundles are indeed present and operational for Symfony 4.3 - ideas in this direction might help but not only.

推荐答案
Heroku 不会在您的 dyno 中安装开发依赖项.这在此处记录:构建行为.
Heroku will not install dev dependencies in your dyno. This is documented here: Build behaviour.
具体来说，heroku 将运行:
Specifically, heroku will run:
composer install --no-dev --prefer-dist --optimize-autoloader --no-interaction
理论认为 heroku 像代码一样用于生产，因此开发依赖项不属于那里.通常，这些依赖项只会安装在开发人员的机器上，而不是安装在任何已部署的应用程序实例上.
The theory goes that heroku is for production like code, so development dependencies do not belong there. Usually, these dependencies would only be installed on the developers' machines, not on any deployed application instance.
如果你真的在部署的代码上需要这个，我想你应该承认这不是开发依赖而是常规依赖，并将它们从 require-dev 移到 require.
If you really need this on deployed code, I guess you should admit this are not development dependencies but regular dependencies, and move them from require-dev to require.
