You need to install dev tools

sudo apt-get install libssl-dev

CodePudding user response：

Puma 3.6 is only compatible with the very old (and not supported anymore) version 1.0.2 of OpenSSL. As such, you will only be able to use this version of Puma on very old operating systems who still ship this old version of OpenSSL.

The first version of Puma to support OpenSSL 1.1.0 (which e.g. with Ubuntu 18.04) is Puma 3.7.0.

If you use an even newer operating system shipping only OpenSSL 3.0, you need at least Ruby 3.1 and Puma 5.6.0.

To fix your issue, you should thus update your Puma version.
