我正在尝试将Sylius应用程序部署到Heroku。在执行构建过程时失败，并出现以下错误：

我已经尝试了Heroku文档中建议的所有方法来增加内存限制https://devcenter.heroku.com/articles/php-concurrency#tuning-concurrency-using-memory_limit
但建议的方法都不会更改内存限制，内存限制仍为128 M，请参见错误：Allowed memory size of 134217728 bytes exhausted

• 在根文档中找到了内容为memory_limit = 256M的用户.init。在我的示例/public中
• 在根文档和顶级文件夹中找到fpm_costum.conf，内容为php_value[memory_limit] = 256M，将Procfile更改为：web: heroku-php-apache2 /public -F fpm_custom.conf

我没办法了...
