Can't find the PostgreSQL client library (libpq)
(23 answers)
Closed 8 years ago.
I am having trouble install postgres on OSX mavericks. I have tried to follow the numerous guides on Stackoverflow with no luck. I installed the postgres.app and also postgres. I have found my pg_config file and tried this command:
gem install pg -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.3/bin/pg_config
But I am still getting this error

This could take a while...

This also seems to be working:
Can't find the PostgreSQL client library (libpq)
$ sudo su
$ env ARCHFLAGS="-arch x86_64" gem install pg
I had the same problem a couple days ago and this worked for me:
brew install libpqxx
Rails 3 - can't install pg gem

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Figured it out: I had some dependency's in my homebrew that was out of date.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 don't want to have installed postgre via browser app download, i want it via brew package, so there is a way to install the annoying libpq ?
You shouldn't need libpq for postgres to work with ruby on Mac OSX.
If you installed postgres with Postgres.app, you sould be able to remove it by simply moving postgres.app to the trash can and deleting the data directory from ~/Library/Application Support/Postgres (only if you want to delete all existing postgres databases on your machine)
Then, with homebrew, install postgres via brew install postgresql. The pg gem should work directly with the postgres Homebrew install.
I have a rails app that I want to start working on, but I just can't get past this one error. I cannot install the pg -v -0.10.1 gem I have tried reinstalling Postgressql from my entire system and that didn't work. I have tried to run the command below and it works successfully but I still can't run bundle install successfully.
env ARCHFLAGS="-arch x86_64" gem install pg
I followed the instructions of this thread step by step but no cigar.
I just keep getting the error message below.

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 XAMPP as my installation folder for PostgreSQL 9.3.
C:\xampp\pgsql\9.3
And now I'm trying to install PostgreSQL gem using that directory as a reference:

But this command failed with errors listed below:

When I checked inside pgsql, there was actually a file named libpq.dll inside of
C:\xampp\pgsql\9.3\lib
So why did the error say it couldn't find the PostgreSQL client library (libpq)??
Is there any solutions for this error?
FYI, I'm using:
Windows 8.1 64-bit
Ruby 2.0.0 64-bit
Rails 4.1.1
Devkit 4.7.2 64-bit
PostgreSQL 9.3.4 64-bit
And I'm trying to install PG Gem version 0.17.1
As a follow-up to the comments, it looks like you've got to use 32-bit Postgres on Windows.
This is most likely to do with the idea that the pg gem works with mingw32, although I'm not totally sure
