Question

Composer无法在生产环境中安装symfony。一切都在开发中运作良好。所有权限都没问题。

PHP Fatal error:  Uncaught Symfony\Component\Debug\Exception\ClassNotFoundException: Attempted to load class "SensioGeneratorBundle" from namespace "Sensio\Bundle\GeneratorBundle".
Did you forget a "use" statement for another namespace? in /home/ev/app/AppKernel.php:25
Stack trace:

这是AppKernel.php的第25行：

$bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();

欢迎任何建议：）

Answer 1

在Prod environnment中，不会注册SensioGeneratorBundle。应该将此包定义为开发包，如下所示：

if (in_array($this->getEnvironment(), array('dev', 'test'))) {
        $bundles[] = new Symfony\Bundle\DebugBundle\DebugBundle();
        $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
        $bundles[] = new Sensio\Bundle\DistributionBundle\SensioDistributionBundle();
        $bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
    }

在作曲家文件中：

"require-dev": {
    "sensio/generator-bundle": "~2.3"
}

如果你想在Prod env中使用这个包中的生成命令，你应该将声明从dev移到Prod（不推荐！）

Answer 2

这也取决于您的目标：

如果要设置产品环境，请运行composer install --no-dev和SYMFONY_ENV=prod，错误应消失。

Answer 3

这对我有用：

$ cd project_folder
$ composer dump-autoload

这将重新加载文件并加载您的设置。

Answer 4

就我而言，Symfony 4 中不推荐使用 Sensio Generator Bundle，因此您可以评论或删除下面的 2 行。

    if (in_array($this->getEnvironment(), array('dev', 'test'))) {
        $bundles[] = new Symfony\Bundle\DebugBundle\DebugBundle();
        $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
         //$bundles[] = new Sensio\Bundle\DistributionBundle\SensioDistributionBundle();
        //$bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
    }

Answer 5

在 Symfony 3.x 中，您只需在AppKernel.php中对此行进行评论：

if ('dev' === $this->getEnvironment()) {
        //   Comment This line  $bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
            $bundles[] = new Symfony\Bundle\WebServerBundle\WebServerBundle();
        }
