Symfony 4 不在生产环境中构建：尝试从命名空间加载类“WebProfilerBundle”

Question

Symfony 4 确实在 Dev 模式下构建，但在产生错误时不要在 Production 模式下：

尝试从命名空间加载类“WebProfilerBundle”。

WebProfilerBundle 确实已安装，但只能在开发环境中使用，而不应在生产版本中使用。

我在 Fedora30 上，不涉及容器化。

• php -v => PHP 7.3.8 (cli)（构建时间：2019 年 7 月 30 日 09:26:16）（NTS）
• npm -v => 6.9.0
• yarn -v => 1.17.3
• composer.phar -V => Composer 版本 1.9.0 2019-08-02 20:55:32
• symfony -V => Symfony CLI 版本 v4.6.4（2019 年 8 月 13 日星期二 16:14:53 CEST）
• 弹性

活动文件版本控制让我猜测使用了生产构建链（不存在开发构建）：

生产版本是用以下方式构建的：

• 做$cp .env.local.prod .env.local这包含..
  • 同.env
  • 除此行APP_ENV=prod
  • 除了缺少的 APP_SECRET 行
• 做$rm -rf var/cache; rm -rf vendor
• 做$../composer.phar install --no-dev --prefer-dist --optimize-autoloader --no-interaction
• 做$yarn build
• 在完成构建时执行 $ rm .env.local

但这似乎不起作用，它会从上面产生错误。

开发构建完成：

• 做$rm .env.local just use .env with APP_SECRET and APP_ENV=dev
• 做$rm -rf var/cache; rm -rf vendor
• 做$../composer.phar install
• 做$yarn encore dev

我想知道的是，也许它的帮助，在 public/index.php 中也是调试“命令”：

use App\Kernel;
use Symfony\Component\Debug\Debug;
use Symfony\Component\HttpFoundation\Request;

require dirname(__DIR__).'/config/bootstrap.php';

if ($_SERVER['APP_DEBUG']) {
    umask(0000);

    Debug::enable();
}

if ($trustedProxies = $_SERVER['TRUSTED_PROXIES'] ?? $_ENV['TRUSTED_PROXIES'] ?? false) {
    Request::setTrustedProxies(explode(',', $trustedProxies), Request::HEADER_X_FORWARDED_ALL ^ Request::HEADER_X_FORWARDED_HOST);
}

if ($trustedHosts = $_SERVER['TRUSTED_HOSTS'] ?? $_ENV['TRUSTED_HOSTS'] ?? false) {
    Request::setTrustedHosts([$trustedHosts]);
}

$kernel = new Kernel($_SERVER['APP_ENV'], (bool) $_SERVER['APP_DEBUG']);
$request = Request::createFromGlobals();
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);

非常感谢@msg 解决了这个问题。我的期望是环境变量只对创建构建很重要，并且它们在某种程度上是静态的。但正如here 已经解释的那样，环境变量在运行时也很重要。所以因为我在构建后删除了我的 .env.local，所以运行时环境立即改回了 dev。
