Your $DYLD_LIBRARY_PATH does not contains /usr/local/mysql/lib directory, so there are 2 solution
symlink
add /usr/local/mysql/lib to $DYLD_LIBRARY_PATH in .bashrc or somewhere
Don't know if this answer is helpful or not ... but I ran into the same problem of sorts this week.
When I googled around for an answer, the one that I found helpful was just to put gem 'thin' in Gemfile.
(of course, this is reliant on having installed the thin gem already)
Then run bundle install after that. (this installs the thin gem).
When you run rails server, it'll work with thin automatically.
Hope this helps!
edit: changed bundle to bundle install
edit 2: added the sentence about thin gem
It looks like your mysql2 gem is not properly installed. Take a look at the answer to this question. It should help you set it up. You need to first install mysql (I like using homebrew to do this). Then gem install with the proper path.

I'm trying to start a server on rails but it isn't working, any ideas on why that might be? I haven't edited the proyect, this is my first try at starting it. I've reinstalled gems and used bundle install with some different options, but all to no avail. I'm working on Windows.

Bundle Install
Could be wrong, but certainly seems you have a lack of the mysql2 gem, or the mysql files Rails needs to load your app.
Confirmation of this would come if you performed bundle install on your system - I surmise the mysql gem would fail
MYSQL Gem
Considering you're on Windows, you've probably not got the MYSQL2 gem installed - standard issue which we wrote a tutorial about here:
Install any MYSQL C-Connector Header files on your system
Install the mysql2 gem with the relevant arguments
Copy the libmysql.dll file to your ruby/bin directory
The C-Connector header files are vital for Windows, as they allow your system to "read" the MYSQL commands / requests. These are not installed by default, so you have to install them yourself (it's only to install the gem, then you can get rid of them if you want):
Install this file, then you can use the following install command:
gem install mysql2 --platform=ruby -- '--with-mysql-dir="C:\mysql-connector-path"'
This should install the gem on your system, which you'll then be able to finish by transferring libmysql.dll from your mysql files' bin directory to your ruby/bin directory:
May be, in other way you should try virtual machine with Linux (Ubuntu).
I started first time rails with Windows but it was so hard to operate gems and environment.
Attempting to switch from WEBrick to Unicorn, I've got the Unicorn gem v 4.8.1 installed on my machine [via "gem install unicorn"] and it's also located in my Gemfile ["gem "unicorn", "~> 4.8.1"], for which I've successfully run bundle install.
However, when starting the server locally via "rails s" (worked fine pre-Unicorn), I get the following error:
...../vendor/cache/ruby/1.9.1/gems/unicorn-4.8.1/lib/unicorn/const.rb:44:in `require': cannot load such file -- unicorn/version (LoadError)

I'm thinking this may be due to using RVM? When I type 'which gem "unicorn"' I get:

/Users/johndoe/.rvm/gems/ruby-1.9.3-p392/bin/unicorn

"bundle show unicorn" gives: /Users/johndoe/Sites/my_app/vendor/cache/ruby/1.9.1/gems/unicorn-4.8.1
The application successfully deploys to Heroku, so I believe this issue is isolated to my machine (rather than being an issue with the application). Any ideas on how to solve this?
I seemed to fix the problem by uninstalling the gem via "sudo bundle exec gem uninstall unicorn", then reinstalling it via standard "sudo bundle install"
Still not sure exactly why the issue occurred, but that fix did seem to work.
Can you used this..
$ rails server unicorn
or
bundle exec unicorn -p 3000
Still not sure what caused this problem.
I solved this simply by reinstalling the unicorn gem.
gem uninstall unicorn
bundle install
bundle update
Heyo. I apologize in advance if this question has been answered in another thread. I've searched through the site but I didn't find an answer. However, the closest related issue was Ruby on Rails / PostgreSQL - Library not Loaded error when starting server- libq.5.dylib, but it was never resolved, and the answer doesn't help me.
I'm trying to get PostgreSQL running on my Mac OSX 10.6.8. I already have Ruby 1.9.3p392 and Rails 3.2.13 installed.
Since I've 10.6.8, and PostGresApp requires 10.7+, I tried installing PG using the manual installer (v9.2.3) available here: http://www.enterprisedb.com/products-services-training/pgdownload
I first installed it to its default path at: /Library/PostgreSQL/9.2/. I then installed the pg gem (PATH=$PATH:/Library/PostgreSQL/9.2/bin sudo gem install pg). When I tried rails s to launch my localhost, I got the error below.
After some reading, I guessed it might be a path error, so I removed the pg gem, and then used the postgresql uninstaller. I then reinstalled pg in /users/stewartmccoy/Library/PostgreSQL/9.2/...and then reinstalled the pg gem. But I still get the same error.
Any thoughts on how I might correctly install PostgreSQL and get my rails server running?

The key part of the error is:
Library not loaded: libpq.5.dylib (LoadError)
This suggests that ruby can't find libpq at runtime. To address that you should probably set the DYLD_LIBRARY_PATH environment variable to point to the lib directory of your PostgreSQL install, either globally or in a wrapper script you use to start Rails. See this superuser question for some more info.
The Pg gem can find the library during compilation and installation because the pg_config executable is on the PATH and it uses that to find libpq. It appears that it doesn't store the path for use at runtime so you have to set the runtime dynamic linker up yourself.
A simple wrapper script (in case you don't want to modify your global environment) is something like:
#!/bin/bash
export DYLD_LIBRARY_PATH=/path/to/pg/lib
exec rails "$#"
The "$#" basically means "pass all arguments to this script through as if they were passed here directly". It preserves quoting correctly and essentially means that the rails command can't tell you didn't run it directly.
I wanted to put my two cents here to answers above.
Sometimes it's enough to just reinstall pg gem.
gem uninstall pg && gem install pg
In my case I upgraded postgresql server from 9.6 up to 14.x and dylib paths were changed.
/opt/local/lib/postgresql96/libpq.5.dylib -> /opt/local/lib/postgresql14/libpq.5.dylib
The gem uses pg_config to determine paths to /opt/local/lib/postgresql[version] folder (named PKGLIBDIR). To build native library for the gem rake sets paths to dynamic libs by fetching them from pg_config in compile. Once pg gem is compiled the paths are linked forever. So, the reinstallation recompiles and relinks path to the new libraries.
A similar stackoverflow answer proposed removing Postgres.app from your PATH, uninstalling the pg gem, and installing the pg gem again.
(I'm not taking the time to check carefully if that applies to this problem, but it solved a problem I had and I want to spread that solution around since I had trouble finding it.)
I have tried various installation methods for deploying a WEBrick and mongrel from the terminal. When I enter the rails server command I get the following:

I have installed the gem both locally and at the root level, and I also have navigated to the application folder before issuing the command. Any help would be appreciated!
Webrick will install automatically if you install rails in a correct manner.
Try this link
Here
And if you don't want to install rails again, try to install server using gem command
Dont forget to include the gems in Gemfile and to run "bundle install"
If you are using Rails < 3.1 you need to use version ~> 0.2.7 of the mysql2 gem
Checkout the documentation and search for active record: https://github.com/brianmario/mysql2
I'm not sure if that will help solve this problem directly, but it may solve others that you may encounter.
Just update your bundler, maybe of any-one of the older gem is conflicting with latest one, this type of issues arises.
gem install bundler
and then bundler install
If you find again error, then delete GEM.lock file, then run
bundler install
This may resolve the issue.
Going through the Lynda training for Ruby on Rails and got to the point where I am starting the WEBrick sever via the rails s command. I am in the same directory as the video /Users/myuser/Sites/simple_cms
I get the following error:

I followed the instructions # Unable to start rails server
Still getting the error. I also followed the directions # rails server fails to start with mysql2 using rvm & ruby 1.9.2-p0 on OSX 10.6.5
Any help would be appreciated.
Okay so after further research I found my own answer
sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib
This did it for me. Just incase anyone else can't move past this problem with the original solutions.
