PHP致命错误：未捕获的Symfony \ Component \ Debug \ Exception \ ClassNotFoundException

Question

我尝试在Amazon Web Service的Elastic Beanstalk上使用Symfony 4.0.6发布我的Web应用程序。但是，当应用程序部署时，我遇到了“脚本缓存：清除返回错误代码255 !!（Executor :: NonZeroExitStatus）”的问题

我更新了symfony / flex（v1.0.70 => v1.0.71），我已经检查了以下内容。

$ composer install --no-dev --optimize-autoloader

我认为我们需要检查以下三个捆绑包

class Kernel extends BaseKernel
{
    public function registerBundles()
    {
        $contents = require $this->getProjectDir().'/config/bundles.php';
        foreach ($contents as $class => $envs) {
            if (isset($envs['all']) || isset($envs[$this->environment])) {
                **yield new $class();**
            }
        }
}

cat /config/bundles.php

    Symfony\Bundle\DebugBundle\DebugBundle::class => ['dev' => true, 'test' => true],
    Symfony\Bundle\TwigBundle\TwigBundle::class => ['all' => true],
    Symfony\Bundle\WebProfilerBundle\WebProfilerBundle::class => ['dev' => true, 'test' => true],

你能给我一个建议吗？

我认为问题是你没有传递APP_ENV环境变量，所以脚本cache:clear在开发模式下运行。

你应该运行APP_ENV=prod composer install --no-dev --optimize-autoloader

这也提到了https://symfony.com/doc/current/deployment.html#c-install-update-your-vendors

另一种选择是运行composer install --no-dev --optimize-autoloader --no-scripts，额外的标志不会执行任何脚本，但我不知道你的应用程序是否依赖脚本来运行。
