Symfony将dev更改为prod

Question

我有以下问题，我把symfony放在服务器上，我在app_dev.php调试中将其更改为false，在app.php中更改为true，现在我应该在信息php-bin/console中获取我有一个prod的设置版本的信息，为什么dev一直向我显示？当然，调试栏不会出现，在进入url app_dev.php_profiler后，我会得到一个错误

Error: Can not redeclare class SymfonyComponentDebugErrorHandler

然而，在输入example.com/_profiler后，我得到了错误：

No route found for "GET /_profiler"

php bin/console关于结果，当我将dev更改为false时，将prod更改为true

如果你想在生产服务器或类似的服务器中调试代码，我认为至少有一条黄金法则：不要修改app_dev.php或app.php。你可以像往常一样保持你的prod-env，同时，你可以用相应的环境(即"dev"，你已经有了"prod")和端口运行webserver捆绑包。正如你所知道的，代码中的任何更改都是在dev中动态编译的，而在prod中，您必须清除缓存(甚至授予适当的web服务器权限)。据我所知，你不希望有任何不同，所以我建议恢复对app*.php脚本的更改，并相应地运行webserver捆绑包。
