I'm attempting to run bundle in my Rails project on OSX 10.9. It fails when getting to the pg gem with this error:

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

Answer 1

Also make sure that you've upgraded Xcode to re-install command line tools on Mavericks. In terminal type:

xcode-select --install

Then follow the prompts.

This doesn't work for me. I get "Can't install the software because it is not currently available from the Software Update server." From the CLI installer. Further research showed that Xcode 5 comes default with CLI tools. Sayanee's answer worked for me. – Bobbette

@JosephJuhnke I had the same issue. You can download and install manually from the Apple website. That worked for me.developer.apple.com/downloads/… – Quartet

Oddly, I recall that I had installed this software recently, but running the installer again as prescribed, fixed my issue. Thanks! – Antiphonal

I had Xcode installed but had not agreed to the license. Running sudo xcodebuild -license solved the problem. – Dumbarton

Answer 2

For me it worked when I did:

brew install postgresql

Adelbert

sometimes you need to gem uninstall pg after you brew install postgresql – Goahead

worked for me! looks like using brew fixes the issue – Quinary

Answer 3

this worked for me with Mavericks and the Postgresapp:

gem install pg -v '0.17.0' -- --with-pg-config=/Applications/Postgres93.app/Contents/MacOS/bin/pg_config

Uretic

worked for me too, for those copying this command pay attention to your Postgres.app name in the path – Urial

Postgres/Contents/Versions/9.3/bin/pg_config for anyone installing with OS X Postgres app – Lucindalucine

Answer 4

Try using the --with-pg-config argument:

bundle config build.pg --with-pg-config=/usr/pgsql-9.1/bin/pg_config

To show the path of the pg_config:

which pg_config

---

For Ubuntu users:

sudo apt-get install postgresql
sudo apt-get install libpq-dev

Then:

bundle install

Answer 5

For me using Mavericks, Rails 3.2.13, Ruby 2.0.0-p247, PostgreSQL 9.1, I needed todo this:

gem install pg -v '0.15.1' -- --with-pg-config=/Library/PostgreSQL/9.1/bin/pg_config

Alialia

thanks, this worked for me to with version 9.3.1 on osx mavericks final – Mealtime

Answer 6

This worked for me on Mac OS X 10.9.3 and Postgres.app version 9.3.4.2:

1) Install Postgres.app

2) bundle config build.pg --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.3/bin/pg_config

3) gem install pg -v '0.17.1'

4) bundle install

Oxbow

What worked for me was gem install pg -v '0.18.1' -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.3/bin/pg_config – Diacid

Answer 7

I've just got it running by doing

ARCHFLAGS="-arch x86_64" gem install pg

after installing posgres using brew

Corby

Answer 8

When i try to install

apt-get install libpq-dev

Failed to install, unmet dependencies problem, to solve

apt-get remove libpq5

then install

apt-get install libpq-dev

Finally solved the gem pg issue.

Jaffe

Answer 9

The following worked for me:

gem install pg -v '0.18.1' -- --with-pg config=/Library/PostgreSQL/9.3/bin/pg_config

Answer 10

You have to configure pg with your current version I used mine 9.4 version on Yosemite. Here is the following command

bundle config build.pg --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.4/bin/pg_config 

You should use your own version

bundle config build.pg --with-pg-config=/Applications/Postgres.app/Contents/Versions/(YOUR POSTGRES VERSION)/bin/pg_config 

then do

bundle install

Answer 11

An error occurred while installing debugger (1.6.5), and Bundler cannot continue. Make sure that `gem install debugger -v '1.6.5'` succeeds before bundling.

I was able to fix this error by rolling back to Ruby v2.0.0. I was running Ruby 2.1.1, which is not supported for this debugger version. Be sure to check your ruby version if you run into this issue as well.
