Rails vs Ruby Version Clashing-CodePudding

I'm trying to run a Rails app made by a third party. System dependencies as given on the repo are below:

System dependencies

Ruby version- ruby 2.4.2p198

Rbenv version- rbenv 1.1.1

Rails version 5.2.3

Postgresql version- 1.1.4

I was able to install ruby 2.4, but when I try to install rails one of the gems fail to install because my ruby version is too old for it. Below is the screenshot of errors, I tried both installing rails and the specific gem separately.

I'm a total beginner on Ruby, and am currently extremely stuck. Anyone know how to surpass the error?

edit:added gemfile below. it looks like the failing gem racc isn't even used.. but rails doesnt install without it. should i just update ruby to 2.5 and take a chance?

CodePudding user response：

The developers of the racc gem removed support of Ruby 2.4 not so long time ago.

One of the solutions might be to install racc from a specific commit which was made right before the breaking update. Try to add this line to your Gemfile and run bundle install

gem 'racc', git: 'https://github.com/ruby/racc.git', ref: 'd66cd1216669ec8acd05b57a4f0de76cc471938c'

Another solution is to use the previous version of the gem:

gem 'racc','~> 1.5.2'

CodePudding user response：

Can you try to use this line, it will work with you. First update the package index:

$ sudo apt update

Then use this line:

$ sudo apt install ruby-full
