I am trying to install gem pg but keep getting an error returned in my terminal. I have pg installed, i installed it with brew. I ran gem install pg and it just tell me that pg is already installed.
Here is the error I get.
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

An error occurred while installing pg (0.18.1), and Bundler cannot continue.
Make sure that `gem install pg -v '0.18.1'` succeeds before bundling.
To tell system to use the gem you have installed on machine
Try
brew install postgresql
or try
ARCHFLAGS="-arch x86_64" bundle install
I think I had similar problem on MacOS. Once you installed PostgreSQL viw brew, you need to install pg gem like:
gem install pg -- --with-pg-config=/usr/local/bin/pg_config
Check details here. This worked for my MacOS machine.
Good luck!
Here's my fix on ubuntu 20.04:
sudo apt install libpq-dev -y
followed by:
gem install pg -v '0.21.0' --source 'https://rubygems.org/'

let me know what I can do or resources I can find, or even if we can zoom to fix it wanted to launch it by need of week.
The key to my initial problem getting pg gem to install on my m1 was that installing postgresql via brew did not install a library that the pg gem needs to run. This fixed it:
brew install libpq
export PATH="/opt/homebrew/opt/libpq/bin:$PATH"
gem install pg
Figured it out: I had some dependency's in my homebrew that was out of date. all I had to do is
homebrew upgrade
I think.
I tried to install pg Gem on Mac El Capitan, but I always get this error:

1 gem installed
But I run bundle install and get the same error posted in the beginning of this post.
I tried reinstall PostgresSQL from brew.
Try this:
brew update
brew install postgresql
sudo gem install pg -v 'VERSION'
This worked for me:
sudo gem install pg -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.4/bin/pg_config
Remember to change 9.4 to your postgres version, if different from 9.4.
For a basic Rails app, you probably already have SQLite installed, but in your Gemfile, it probably has simply:
gem 'sqlite3'
Do you just need PostgreSQL for production? Make sure your Gemfile has it as follows:
group :production do
gem 'pg'
end
Also, make sure your Gemfile has SQLite just for development:
group :development do
gem 'sqlite3'
end
then try running bundle install.
I'm using/I want to use Postgresql as database, but when I type "bundle install" or "bundle update", I get this error, what do I do to fix this? :)

Looks like you are missing pre-requisite libraries.
sudo apt-get install libpq-dev postgresql-devel
Then install pg
gem install pg
For those on OS X, I recommend using home-brew to install:
brew install postgresql
More info at Homebrew's site, if you're not already a user, including how to set it up.
in order to communicate with a PostgreSQL database backend you need the libpq-dev package.
sudo apt-get install libpq-dev
then continue the package installation
gem install pg
I am getting pretty desperate, i have tried every answer on the subject but nothing seems to work.
the error log looks like this:

I hope someone can help me. tnx
If you already install Postgres.app in Mac,
you should copy /Applications/Postgres.app/Contents/Version/9.4/bin/pg_config to another place. For example /home/pg_config
then run
bundle config build.pg --with-pg-config=/home/pg_config
bundle install
You should find your pg_config file and add it to the build command:
bundle config build.pg --with-pg-config=/usr/local/bin/pg_config
Since your pg_config file is located at /usr/local/bin/pg_config Did you try the command(edited) above?
If that doesn't help maybe try:
env ARCHFLAGS="-arch x86_64" gem install pg
I'm using/I want to use Postgresql as database, but when I type "bundle install" or "bundle update", I get this error, what do I do to fix this? :)
