我正在尝试将我的 Symfony 应用程序部署到 Heroku，但是当我运行命令 git push heroku master 时出现错误：

我的AppKernel::registerBundles()

    public function registerBundles()
    {
        $bundles = [
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
            new Symfony\Bundle\SecurityBundle\SecurityBundle(),

            new Doctrine\Bundle\MigrationsBundle\DoctrineMigrationsBundle(),
            new Stof\DoctrineExtensionsBundle\StofDoctrineExtensionsBundle(),
        ];

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

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

        return $bundles;
    }

composer.json（“需要”块）

    "require": {
        "php": ">=5.5.9",

我需要做什么？

@yivi 是的，非常感谢，它有效。但是现在我收到另一个错误，例如：``` PHP Warning: count(): Parameter must be an array or an object that implement Countable in /tmp/build_c1c44af237acd11b7e49f6c98f7d82b5/vendor/symfony/monolog-bundle/DependencyInjection/Configuration.php on line第654章
这是一个不同的问题，与这个无关。您可能需要提出一个新问题，但如果您花一些时间进行测试和重新研究，这样您的问题就会包含所有必要的细节，这可能会更好。如果我的回答解决了 this 问题，请记住您可以接受它。欢迎使用 Stack Overflow。

【解决方案1】：

你已经安装了“doctrine/doctrine-fixtures-bundle”用于开发：

"require-dev": {
        "doctrine/doctrine-fixtures-bundle": "^3.0",
        "sensio/generator-bundle": "^3.0",
        "symfony/phpunit-bridge": "^3.0"
    },

但正在尝试在生产中使用它。

当您部署应用程序时，heroku 正在使用 --no-dev 标志安装作曲家依赖项，这会跳过在 require-dev 中声明的包。

当应用程序尝试运行AppKernel::registerBundles() 时，它会尝试实例化Doctrine\Bundle\FixturesBundle\DoctrineFixturesBundle，但未安装该包。

您应该删除第 19 行 (new Doctrine\Bundle\FixturesBundle\DoctrineFixturesBundle(),) 并将其添加到以下块中的某处：

if (in_array($this->getEnvironment(), ['dev', 'test'], true)) {
            $bundles[] = new Symfony\Bundle\DebugBundle\DebugBundle();
            $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
            $bundles[] = new Sensio\Bundle\DistributionBundle\SensioDistributionBundle();
            $bundles[] = new Doctrine\Bundle\FixturesBundle\DoctrineFixturesBundle();
           // ^^^^^ this line here

这是检查环境是dev 还是test，并且仅在这些环境中尝试使用这些包。
