I'm attempting to install the byebug gem v5.0.0 in a ubuntu environment. The v 5.0.0 is a project requirement, I can not use a newer version. These are the current versions that I am using
bundle -v
Bundler version 2.1.4
ruby -v
ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-linux-gnu]
bundle -v
Bundler version 2.1.4
rvm -v
rvm 1.29.10 (manual) by Michal Papis, Piotr Kuczynski, Wayne E. Seguin [https://rvm.io]
rails -v
Rails 5.2.3
When I attempt to install with gem install byebug -v 5.0.0 the following is written to cli.
The install appears to be failing when executing the make file for the gem
Even if i attempt to execute make in the /var/lib/gems/2.7.0/gems/byebug-5.0.0/ext/byebug directory, I get the same error message starting with the context.c file.
This seems to be some install issue with the 5.0.0 version, I did attempt to install the newest version of byebug for testing, and it installed successfully.

That version of byebug is from 2015 when ruby was on v2.2.1
If you can’t use a newer bye bug; use the older ruby.
That older version of ruby is probably going to require you to use older versions of all the gems your project needs. Do you have a Gemfile.lock showing the target versions? If not you might have to use ruby gems to find what version each gen was the latest in early 2015.
https://rubygems.org/gems/byebug/versions Shows the version released dates for byebug.
