python - ping 命令未显示在 Heroku 堆栈中（Ubuntu 20.04）

问题描述

Heroku 默认堆栈中没有 ping 命令（使用 Ubuntu 20.04）。我已经使用 buildpack 安装了包“iputils-ping”，但是它没有显示“找不到命令”。还尝试使用 buildpack 的 Aptfile 中特定 .deb 文件的链接。

显示它已安装的部署日志，但是在完成后，找不到命令。无论如何我可以安装该软件包并使用我的python脚本中的ping命令进行部署。

解决方案

它已安装，但是我无法在我的 Python 程序中使用此命令，因为“ping”命令需要 root 权限才能执行 Heroku 不允许:(

~ $ which ping
/bin/ping
~ $
