I am new to rails and attempting to switch my default DB to Postgres from SQLite3. I have encountered an error. I am using gem install pg and getting this error error: Error installing pg: ERROR: Failed to build gem native extension. I am using Mavericks OSX and Ruby 1.9.3, Rails 3.2.12, and PG 9.3 –The goal is to deploy a sample app to heroku (which doesnt seem to support SQLite.
Steps I have tried:

It's trying to build the gem pg, which has C or C++ code in it, and the compilation phase is not working. Under OS X, you must install XCode or get a compiler by other means, and the shell you're using to run bundle install must have the compiler in its path. I've compiled pg many times under OS X, though I have not upgraded to Mavericks.
If you have XCode installed, the above paragraph doesn't apply. You'll get additional information on what's going wrong if you try gem install pg. Try that and post the results.
The key is "You have to install development tools first." This is a strong hint that you don't have a proper compiler. This page says XCode must be v5.01 or later.
Thanks all for your help. The specific issue was resolved by me running the below command in terminal
brew install apple-gcc42
To clarify, I had the most recent XCode (with command line) and Mavericks, Ruby 1.9.3, Rails 3.2.12, and PG 9.3. I am unsure why that specific command worked when I already had the command line tools installed. The one change of the output of
gcc--version
was that --prefix=/Library/Developer/CommandLineTools/usr
changes to
--prefix=/Applications/Xcode.app/Contents/Developer/usr
Again, this change worked in practice, but I am not sure why this fixed things.

I am trying to deploy Rails to Elastic Beanstalk using a simple 3-step CodePipeline process. Step 1 takes the source from GitHub, gives it to CodeBuild, which then should create the build and pass it to EB.
For some reason, when the CodeBuild process reaches the pg gem, it fails with the following error:

Your PostgreSQL is too old. Either install an older version of this gem or
upgrade your database to at least PostgreSQL-9.3.

I had the same problem you had above too (except without using CodeBuild). The issue is that you're trying to install the pg gem at version 1.3.5.
At the time of writing, Elastic Beanstalk on Amazon Linux 2 (AL2) ships with Postgres version 9.2 by default (incredibly old 😔). Whereas the pg gem dropped support for 9.2 after version 1.2.3. See here.
So your 2 options are either:
Enhance EB to install a more recent version of Postgres during the build & deploy process, for example as described here: https://stackoverflow.com/a/63204453/1852005.
Or you could just use version 1.2.3 of the pg gem by configuring that version in your Gemfile. That version shipped in 2020-03-18.
Either of those options should get you past that error.
Note that your application may also connect to Amazon's RDS which has a more recent Postgres version. However that RDS lives on another server, so don't get the two confused! You can see the difference if you eb ssh to the server and run e.g: this on the shell directly:
[root#ip-XXX-XX-XX-XXX current]# psql --version
psql (PostgreSQL) 9.2.24
compared with running this on a Rails console which shows the RDS version:
irb(main):001:0> ActiveRecord::Base.connection.select_value('SELECT version()')
=> "PostgreSQL 11.13 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 7.3.1 20180712 (Red Hat 7.3.1-12), 64-bit"
I can't install the pg gem when I run bundle, or when I try to install it separately. The error I get is: "could not create Makefile." I'm running Mountain Lion, have Xcode installed, and have command line tools installed. I also have Postregsql installed via homebrew.
I believe the error is because I can't create the makefile, which has surfaced as the error preventing me from doing other things.
The full error I get is below.
This error happens during the bundle. The other gems are installed fine, or are marked as using, then this error terminates the bundle while installing pg (0.14.1) with native extensions

I'm really at a loss for what to do here. I've been working on this for two days.
EDIT:
So when trying to find the path to implement the solution Christian Rapp suggested I found this recommendation: sudo env ARCHFLAGS="-arch x86_64" gem install pg which worked to install pg. Unfortunately I'm getting errors when I try to run rails s, rake db:create:all, or rake db:migrate. I'll create a separate question to trace those problems down ...
I am not using homebrew on MacOS but where does it install libpq? MacPorts is using /opt and your configure script does not know anything about this. The error messages is quite informative just provide the path with something like
gem install pg -- --with-libpqlib=/opt/...
May be you have to use another flag to provide the necessary Informations
The error is this:
Can't find the PostgreSQL client library (libpq)
You'll need to install PostreSQL (I recommend using Homebrew, but there are probably other downloads available) and try to install the gem again.
"Can't find the PostgreSQL client library (libpq)"
This is the reason your makefile can't be created. Your Postgres libraries, specifically libpq can't be found on your path. I see you installed with Homebrew. I don't use homebrew so I don't know if it sets the path for you.
I'm suddenly running into this issue when running 'bundle install'. Everything seems to be installing correctly, but then I run into an issue with 'pg', as so many others seem to do. As the message says, I try running 'gem install pg - '0.12.2'' but it still fails.
I'm on Snow Leopard 10.6 and this is the error I'm getting:

First you need to make sure you have command line tools (package for Xcode) installed. Since you're on old version of OSX - you will have to research how to do that.
Than, using homebrew install postgress
brew install postgres
After that, everything should bundle with no issues.
It appears that you do not have postgres installed properly. I got a similar error when I was trying to install a pg module with npm. It disappeared after installing postgres properly.
Here's a link to download: http://www.postgresql.org/download/macosx/
If you run rails on your machine only in dev mode and use sql lite for that, you need don't need to install the production bundles.
So if your gemfile looke like that:
group :production do
gem 'pg'
end
Try installing the bundles with the following command:
gem install --without production
I've looked all the solutions in the internet for this, reinstalled everything and still nothing... When i do gem install pg i get:

I tried setting the pg_config path, my xcode is installed, my command line tools from xcode is installed, my ruby version is 1.9.3 installed by RVM.
My mac is OS X Mountain Lion
Thanks guys!
You're missing the Postgres client library header files (libpq-fe.h). In Debian the package is called libpq-dev. I don't know Mac packaging at all, but if there's no Mac respository building the PG client libs from source would work.
i would recommend installing rvm https://rvm.io/rvm/install
then run rvm requirements. this will install all required packages, you're probably missing "gcc49" after this install rails and yore good to install postgres. i would suggest postgresapp or postgresql.
I am not sure what happened - I know Postgres was working right after the upgrade to Lion, but it is not working anymore. I have Xcode 4 installed.

EDIT*** I tried installing postgres via homebrew and got the following errors:
Warning: You have no /usr/bin/cc.
This means you probably can't build *anything*. You need to install the Command
Line Tools for Xcode. You can either download this from http://connect.apple.com
or install them from inside Xcode's Download preferences. Homebrew does not
require all of Xcode! You only need the Command Line Tools package!
Warning: Setting DYLD_LIBRARY_PATH can break dynamic linking.
You should probably unset it.
Warning: Your Homebrew is outdated
You haven't updated for at least 24 hours, this is a long time in brewland!
Warning: Unbrewed dylibs were found in /usr/local/lib.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.
Unexpected dylibs:
/usr/local/lib/libruby.1.8.7.dylib
Warning: Unbrewed static libraries were found in /usr/local/lib.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.
Unexpected static libraries:
/usr/local/lib/libruby-static.a
Warning: Your compilers are different from the standard versions for your Xcode.
If you have Xcode 4.3 or newer, you should install the Command Line Tools for
Xcode from within Xcode's Download preferences.
Otherwise, you should reinstall Xcode.
Warning: /usr/bin occurs before /usr/local/bin
This means that system-provided programs will be used instead of those
provided by Homebrew. The following tools exist at both paths:
bundle
edit_json.rb
erb
erubis
gem
irb
prettify_json.rb
rails
rake
rake2thor
rdoc
ri
ruby
testrb
thor
tt
update_rubygems
Consider amending your PATH so that /usr/local/bin
is ahead of /usr/bin in your PATH.
Warning: Your Xcode is configured with an invalid path.
You should change it to the correct path. Please note that there is no correct
path at this time if you have *only* installed the Command Line Tools for Xcode.
If your Xcode is pre-4.3 or you installed the whole of Xcode 4.3 then one of
these is (probably) what you want:
sudo xcode-select -switch /Developer
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
