I am trying to execute bundle install on a rails project, after installing rails and ruby following this guide, but I am getting the following message:
em files will remain installed in /home/home/.rbenv/versions/2.7.1/lib/ruby/gems/2.7.0/gems/pg-1.1.4 for inspection.
Results logged to /home/home/.rbenv/versions/2.7.1/lib/ruby/gems/2.7.0/extensions/x86_64-linux/2.7.0/pg-1.1.4/gem_make.out
An error occurred while installing pg (1.1.4), and Bundler cannot continue.
Make sure that `gem install pg -v '1.1.4' --source 'https://rubygems.org/'` succeeds before bundling.
In Gemfile:
pg
And after executing:
gem install pg -v '1.1.4'
I get
Building native extensions. This could take a while...
ERROR: Error installing pg:

I have checked the file gem_make.out on vim and it seems to contain the same message copied above.
