php - 推送到 Heroku 应用程序失败(安装后 cmd 事件返回错误)- Composer 问题？

Question

去年我在做一个项目，一切都很顺利。从 2015 年 11 月到今天，我都没有碰过它。我做了一些更改，当我尝试推送到 Heroku 时出现以下错误。我用 Composer 尝试了很多东西(composer 更新、composer 安装、删除 composer.lock 和运行 composer install 的 vendor 文件夹)但似乎没有任何帮助。

        ]
    },
    "config": {
        "preferred-install": "dist"
    },
    "minimum-stability": "stable"
}

如果我将 way/generators 更改为 2.* 并将 prologue/alerts 更改为 0.3.0 我可以运行 composer update，但仍然无法推送之后。

有人可以帮忙吗？现在已经坚持了 2 天。

提前致谢!

Answer 1

错误原因如下:

Mcrypt PHP extension required.

启用该扩展以避免错误。
