amazon-web-services - 十六进制安装在 aws 实例上失败，无法获取元数据

问题描述

这是在一个 aws lightsail 实例上，试图部署我的 phoenix 应用程序，混合 local.hex 失败，知道如何解决这个问题吗？

可能是 DNS 问题，但不确定。

Could not install Hex because Mix could not download metadata at https://repo.hex.pm/instal
ls/hex-1.x.csv.

 mix local.hex --force

解决方案

阅读完整的错误，我认为问题在于 lightsail 实例上没有安装 OpenSSL。您必须先安装 openssl。你如何做到这一点取决于操作系统。例如，在 linux 上，可以这样做：

sudo apt install openssl
