I can't install pg in Slackware

Time:03-22

I need to run a ruby project with gems and specs. When I type bundle install I received:

bash-5.1# bundle install
Don't run Bundler as root. Bundler can ask for sudo if it is needed, and
installing your bundle as root will break this application for all non-root
users on this machine.

An error occurred while installing pg (1.3.4), and Bundler cannot
continue.

In Gemfile:
  pg

I am trying to convince them to switch to Slackware as the main OS but I am having trouble installing and running the skeleton program that uses psql, ruby and soon enough ruby on rails.

I installed libpqxx slackbuild, sqlite3 gem, postgresql (14.2) slackbuild and when I run rnu ./import_db.sh it says: bash-5.1# ./import_db.sh dropdb: error: connection to server on socket "/tmp/.s.PGSQL.5432" failed: No such file or directory Is the server running locally and accepting connections on that socket? createdb: error: connection to server on socket "/tmp/.s.PGSQL.5432" failed: No such file or directory Is the server running locally and accepting connections on that socket? psql: error: connection to server on socket "/tmp/.s.PGSQL.5432" failed: No such file or directory Is the server running locally and accepting connections on that socket? bash-5.1#

CodePudding user response:

I've just realised that Slackware uses slackpkg as package manager. Not quite sure if this is the library you need, but try installing with:

slackpkg install libpqxx
