UGH... I broke my (formerly functioning) Rails setup - under OS X Yosemite. I did so using Homebrew to update my version of Git. After getting Git where I want it, running 'rails c' gives these errors:
/Users/grogers/.rbenv/versions/2.0.0-p353/lib/ruby/gems/2.0.0/gems/pg-0.16.0/lib/pg.rb:4:in `require': dlopen(/Users/grogers/.rbenv/versions/2.0.0-p353/lib/ruby/gems/2.0.0/gems/pg-0.16.0/lib/pg_ext.bundle, 9): Library not loaded: /usr/local/lib/libpq.5.6.dylib (LoadError)

Reason: image not found - /Users/grogers/.rbenv/versions/2.0.0-p353/lib/ruby/gems/2.0.0/gems/pg-0.16.0/lib/pg_ext.bundle
Seeing the reference to pg_ext, I tried to verify pieces of my postgresql installation. If I try 'gem install pg' or try to update the gem with bundler, I get this:
Building native extensions. This could take a while...
ERROR: Error installing pg:

Could not create Makefile due to some reason, probably lack of necessary

I'm probably making my problem worse, but I went back and redid a 'brew install postgres' but still get the same error.
Any help appreciated. Thank you!
Did you also upgrade Postgresql via Homebrew? If not, what version of Postgres are you running, and how do you install it?
If you did upgrade your Postgres you'll need to rebuild the native bindings for the pg gem: gem uninstall pg && gem install pg.

I 'm using new MACBook PRO (chip: Apple M2) and trying to set up rails application but therubyracer gem is not installing. I tried below steps but didn't work
brew install v8#3.15
gem install libv8 -v '3.16.14.19' -- --with-system-v8
gem install therubyracer -- --with-v8-dir=/opt/homebrew/opt/v8#3.15
when i tried with 'brew install v8#3.15' it gives below error
Warning: v8#3.15 has been deprecated because it depends on Python 2 to build!
Error: v8#3.15: no bottle available!
If you're feeling brave, you can try to install from source with:
brew install --build-from-source v8#3.15
It is expected behaviour that most formulae will fail to build from source.
It is expected behaviour that Homebrew will be buggy and slow when building from source.
Do not create any issues about failures building from source on Homebrew's GitHub repositories.
Do not create any issues building from source even if you think this message is unrelated.
Any opened issues will be immediately closed without response.
Do not ask for help building from source from MacHomebrew on Twitter.
You may ask for help building from source in Homebrew's discussions but are unlikely to receive a response.
If building from source fails, try to figure out the problem yourself and submit a fix as a pull request.
We will review it but may or may not accept it.

I was trying to install rmagick gem in rails 2.3.5 . but I could not install as it shows error. Same error comes in both rvm and system.

ERROR: Error installing rmagick:

this was the error.
Already Installed imagemagick,libmagickwand-dev, libxml2-dev, libxslt-dev,libgraphics-magick-perl, libgraphicsmagick++1-dev, libgraphicsmagick++3, libgraphicsmagick1-dev, libgraphicsmagick3 (tried everything got from google)
Seems like v2.13.4 needs some extra stuff installed, simply not only install libs but also:
sudo apt-get install imagemagick
This fixed it for me.
FYI, I got the following error:
checking for ImageMagick version >= 6.4.9... *** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options.
If you don't need the very latest version, you could try:
gem install rmagick -v 2.13.3
And see if the previous one works for you.
I have tried installing the packet libpq-dev, and installing postgresql, but bundle install still fails due to gem pg. This is the error I get:

What is a proper way to clean up the mess?
If you are on Mac, install Homebrew and then install Postgres using the command
brew install postgresql
Or you can download and install Postgres from here depending on which OS you are using.
There isn't any "mess" - it's a standard issue where your system does not have the required libraries to install the gem
Library
As mentioned in the comments, you first need to install PGSQL, which will create the required library files to help the gem install, after that you can use some path references to help the gem install:
gem install pg -- --with-pg-dir="C:/Program Files/installer
I ran bundle update (so that I can install rails), but got this error:

I'm new to Ruby and all this, could anyone tell me what is wrong here?
This is on OSX
Make sure ton install postgres first. I suggest you do so via homebrew, the Mac package manager.
brew install postgresql
Here is one of the many tutorials on how-to install postgres on a Mac.
EDIT
Looks like the gem can't find your postgres config, here's an answer similar to your problem:

I don't know what I've broken but I can't create any rails apps using sqlite any more.
When I try to run gem install sqlite3 or include sqlite3 in the gemfile for a rails app I get the following.

I'm pretty new to ruby/rails etc so this makes very little sense to me.
I also ran a sudo gem update and ran into the same problem when it tried to update nokogiri.

Any idea/suggestions of what to try to get up and running with sqlite3 would be hugely appreciated.
Using ruby 1.9.2, OSX Lion.
Thanks, mark
The sqlite3 gem has to be compiled and link against the native sqlite3 libraries, so you'll need a C/C++ compiler and the sqlite3 development headers/libraries properly installed.
On Mac OS X, you can do this by installing the latest version of XCode. That should provide the C/C++ development tools and headers that the sqlite3 gem requires. It's a big download, but without it, you can't install the sqlite3 gem using the gem command, so make sure it's installed.
After you've installed XCode, reset your terminal and try running the "gem install sqlite3" again. It should work this time.
Try installing the sqlite3 development headers by running: port install sqlite3 +universal
