I'm trying to set up a Rails project with Vagrant. Using Rails 5.2 as well.
In my original bundle install, it told me
Your user account isn't allowed to install to the system RubyGems.
You can cancel this installation and run:
bundle install --path vendor/bundle
to install the gems into ./vendor/bundle/, or you can enter your password
and install the bundled gems to RubyGems using sudo.
...So I tried that and got:
Fetching pg 1.0.0
Installing pg 1.0.0 with native extensions
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.

To see why this extension failed to compile, please check the mkmf.log which can be found here:
/app/vendor/bundle/ruby/2.5.0/extensions/x86_64-linux/2.5.0-static/pg-1.0.0/mkmf.log
extconf failed, exit code 1
Gem files will remain installed in /app/vendor/bundle/ruby/2.5.0/gems/pg-1.0.0 for inspection.
Results logged to /app/vendor/bundle/ruby/2.5.0/extensions/x86_64-linux/2.5.0-static/pg-1.0.0/gem_make.out
An error occurred while installing pg (1.0.0), and Bundler cannot continue.
Make sure that `gem install pg -v '1.0.0'` succeeds before bundling.
Looking at the log file mentioned has this in it:

Unclear how to proceed and get this working. Would love some help or advice. Thanks!
Edit:
I run sudo apt-get install libpq-dev and then get an error related to and old version.

Your PostgreSQL is too old. Either install an older version of this gem or upgrade your database to at least PostgreSQL-9.2.
