An error occurred while installing pg (1.4.3), and Bundler cannot
continue

.

In Gemfile:
  pg

And on top of that, the repo of the project is created but without an Gemfile.lock
And I have PostgreSQL installed on my computer.
I’m using Ubutu 22.04.1
I have tried a lot of suggestions but still can’t find a way out.
I will really appreciate if somebody could help.

    Run the below commands

    gem install pg -v '1.4.3'
sudo apt-get update
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev postgresql-client-common postgresql-client libpq-dev

    Here’s how I fixed this in my computer.

    First try to install libpq-dev
    sudo apt-get install libpq-dev

    Then the computer would complain about incompatible libpq5 version:

    Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libpq-dev : Depends: libpq5 (= 14.5-0ubuntu0.22.04.1) but 14.5-1.pgdg20.04+1 is to be installed
E: Unable to correct problems, you have held broken packages.

    This means you have newer version of libpq than the one asked by libpq5-dev. Install the correct libpq5 version:

    sudo apt-get install libpq5=14.5-0ubuntu0.22.04.1

    Then try to install libpq-dev again

    sudo apt-get install libpq-dev

    You should be able to do bundle install now
