我正在尝试将 Sylius 应用程序部署到 Heroku。构建过程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

但是建议的方法都没有改变内存限制，它保持在 128M，见错误：Allowed memory size of 134217728 bytes exhausted

将内容为 memory_limit = 256M 的 user.init 定位在根文档中。就我而言 /public
将 fpm_costum.conf 与内容 php_value[memory_limit] = 256M 放在根文档和顶级文件夹中，将 Procfile 更改为： web: heroku-php-apache2 /public -F fpm_custom.conf

我没有想法......

标签： php symfony heroku sylius

【解决方案1】：

发生这种情况是因为您的限制没有传播到作为 post 脚本执行的 cache:clear 脚本。尝试改用 COMPOSER_MEMORY_LIMIT 环境变量：

COMPOSER_MEMORY_LIMIT=512M composer install …

确保您没有覆盖 public/index.php 文件中的此限制。这是我前段时间犯的错误……

请注意，如果添加更多软件包，很快您将不得不将此值增加到一个 gig。 Sylius 会占用大量内存。
