Ruby gem 'byebug 5.0.0' 由于出错而安装失败

Question

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.

Answer 1

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.
