you may get this issue while working on Rails 4.0 and above version along with Ruby 2.0 and above.
this is very common issue if you are going ahead with up gradation of Rails environment.
Steps to be follow-
For Windows System-
1.Download the the newest mysql-connector to c:\mysql-connector folder
2. gem install mysql2 -- '--with-mysql-include="C:\mysql-connector\include" --with-mysql-lib="C:\mysql-connector\lib"
Hopefully it will work for you.
For Ubuntu System-
1. open terminal (Ctrl+alt+T)
2. $ sudo apt-get install libmysqld-dev
Run bundle from your project directory
3. $ bundle
This will resolve the issue.We can also see the solution here.

Now rails app is working fine.
I am trying to install pgsql gem, but I have some strange encoding issue when trying to install. Whole app have just been migrated from windows environment to Linux environment, but only default gemfile was used. I have found that way to solve is to change locale in registry.rb, but as I mentioned, my environment is Linux. Gist of gem_make.out can be viewed here: gist
postgresql is installed and runing:
$ service postgresql status
9.3/main (port 5432): online
EDIT: Seems that this issue is only happening with pgsql gem, other gems are installing sucessfuly, for example, running $ gem install A_123 installs specified gem successfully.
According to similar question on SO, to which SO user grenierm5 pointed me,i t seems that installing ruby-dev headers for compiling extension modules did the trick.
sudo apt-get install ruby-dev && sudo gem install pg
I'm having some trouble installing jekyll. Can't quite figure out how to patch the missing link. I think it's an update to Ruby, but RVM is having trouble installing alternate versions of ruby as well.
Heres the full post:
$ sudo gem install jekyll
ERROR: Error installing jekyll:
ERROR: Failed to build gem native extension.
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb
mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/ruby.h
Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/fast-stemmer-1.0.1 for inspection.
Results logged to /Library/Ruby/Gems/1.8/gems/fast-stemmer-1.0.1/ext/gem_make.out
Does this mean I need to update the version of ruby I'm using via rvm?
Ubuntu
sudo apt-get install ruby-dev
gem install jekyll
Your problem is that either you system doesn't know where make is located at or you don't have it installed. The easiest way to fix this (and probably other issues you'll run into trying to get a ruby system up and running) is to install xcode.
You can get it at http://itunes.apple.com/us/app/xcode/id497799835?ls=1&mt=12 for lion. Or it came on a CD with your computer for earlier versions.
If you're using Lion, please see comments below for a link to how to install developer tools on Lion.
I had the same error on Ubuntu and this helped me sort it out.
You must have ruby-dev installed
apt-get install ruby-dev
If you installed XCode and command line tools are still missing go to Terminal and
xcode-select --install
it will prompt you to install these tools. After that just follow SrBlanco´s answer. That solved the problem for me.
Good luck.
Need to install "make".
I am using Ubuntu 12.10.
sudo apt-get install make
Should work on any Debian based distro.
Note: this problem also occurs on newer MacBook Pro models that come with Mavericks pre-installed. I updated another post with my own solution that didn't involve Xcode at all. My system had the Xcode developer tools installed when I got the machine.
ERROR: Error installing jekyll: ERROR: Failed to build gem native extension
Install Xcode as mentioned if you don't have it installed already (https://developer.apple.com/xcode/). Plus you need the command line tools.
Open Xcode. Go to Preferences > Downloads > Install Command Line Tools
Installing command line tools for Xcode solved the problem for me on my Mac
xcode-select --install.
sudo apt-get install ruby-dev
sudo gem install jekyll
hope this will help, it works with me.
I had this same exact error when trying to install Jekyll, and the following steps from this link helped me. Just in case anyone else comes across this!

I was facing the same issue in my Fedora 22 setup. I had ruby installed but didn't have ruby-devel. Installing ruby-devel fixed the issue for me.
dnf install -y ruby-devel
For older systems:
yum install -y ruby-devel
I followed this on Ubuntu/Linux Mint
sudo apt install build-essential
sudo apt install ruby-dev
sudo gem install jekyll
An addendum: You can install XCode now from the App Store on Mountain Lion. The process is transparent and pretty fast.
I had the same problems with you.
I use Mac OS X 10.9 develop preview version, and I had installed gcc and Xcode.
But my Xcode version is 4.6.
Then I install the Xcode 5.0
After that I type sudo gem install jekyll in the terminal again. Then it works.
Wish it could help someone.
Installing Xcode and going to perferencs > downloads > install commandline tools WORKS!
Same problem on Debian, I had forgot to run this command:
~/.rvm/scripts/rvm
All these answers did NOT work for me.
If you're looking for a solution on ubuntu 14.04, do this:
sudo apt-get install ruby1.9.1-dev zlib1g-dev nodejs
sudo gem install jekyll -v 2.5.3
Unfortunately, nodejs is required because of a bug in Jekyll that enforces existence of runtime JS engine even though it doesn't need one.
For Ubuntu, this helped in my case:
apt-get install libffi-dev
A general advice is to just follow what is displayed as the reason for the error and hopefully you'll be provided with a log file in which the first line suggests which package should be installed, in my case:
To see why this extension failed to compile, please check the mkmf.log which can be found here:
/var/lib/gems/2.3.0/extensions/x86_64-linux/2.3.0/ffi-1.9.21/mkmf.log
MacOS
my solution to this problem
install xcode
type xcode-select --install in the command line
type sudo gem install jekyll in the command line
PS: It is the combination of the two answers in this question.
You are missing the ruby-dev file , just go ahead and run this command - sudo apt-get install ruby-dev
Hope this helps!!
I had the same issue on my macOS(10.14.2), the reason may be:
Apparently with OSX el Capitan, there is a new security function that prevents you from modifying system files called Rootless.
My solution is using rvm:
install ruby on Mac OS X with RVM
gem install jekyll
On windows I have this issue
I actually installed the version rubyinstaller-devkit-2.6.3-1-x64 of ruby
I have removed the ruby completely and Installed the rubyinstaller-devkit-2.5.5-1-x64
and issued the following commands on powershell
gem install bundler
gem install jekyll
and this time no errors where found
I had this issue and of all things, the error was occurring because I hadn't agreed to some updated terms of service in xcode. Running the following did the trick for me. Go figure.
sudo xcodebuild -license accept
For me, I had to upgrade homebrew and install rbenv to the latest ruby version. After that, I followed the instruction at jekyll website. My OS is Catalina 2019, I couldn't install Xcode, which is not compatible yet!
You have to set the path in your .bash_profile to make sure that it initializes the rbenv when you restart your terminal.
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
then
$ rbenv version
2.2.3 (set by /Users/mislav/.rbenv/version)
$ rbenv shell
rbenv: no shell-specific version configured
hope that help!
Here is the (only?) reliable and simple way to install Jekyll on macOS
Install UTM
Install Ubuntu Server
Install Jekyll using Ubuntu instructions at https://jekyllrb.com/docs/installation/ubuntu/
Forward port 22 in the VM settings (22->localhost->22)
Use VS Code on the macOS host
Install Remote SSH
Connect to USER#localhost
Drag and drop the folder on Mac into VS Code (this transfers files to remote)
Enable port forwarding for 4000 (bottom bar on VS Code)
Work on your website
Right click on your website on the file explorer and click download
If you have not done these steps, you might be delighted by:
Ubuntu imports your public SSH key from GitHub
VS Code magically handles file transfer in and out
VS Code magically installs your VS Code extensions onto the remote server and allows file search on the remote host
I am new to ruby on rails development. Just started learning. I installed ruby on rails on my windows 8.1 pc with below packages kit from website.

Run bundle install to install missing gems
I tried to use bundle install command , but then i am getting below error
dl is deprecated please use fiddle
Please suggest
After so much research below are the steps you need to perform.
I am new on ruby on rails and faced so many issues during installation i dont want anyone to face this who are beginers to this
First install ssl_certificate into your ssl_certificate directory of railsinstller.
fire the command gem update --system
fire the command bundle install
install node.js os compitable installer
I have been developing rails applications on windows xp. I now need to deploy these apps to a different computer, which has Ubuntu 10.04.1 LTS. To install ruby and rails on my windows machine, I used the RailsInstaller. I now need to get ruby and rails working on my Ubuntu machine. It isn't connected to the internet so pretty much every tutorial I found hasn't worked. Can I just transfer my installed files from my windows machine? In my RailsInstaller directory on my windows machine, there is the following directories: DevKit, Git, Ruby1.9.3, and scripts. It also has unins000.exe and unins000.dat. Will it work to just transfer these files or is there some other way to get ruby on rails working on my Ubuntu machine?
Windows and Ubuntu are two different operating systems. Read about operating systems here
You cannot copy software files from one Operating system to another. You can only move code and documents (images, music etc).
Anyway, since you are using Ubuntu, the tool that allows you to install software is called 'aptitude'. You will install software 'packages' from the terminal. It is similar to the command prompt in windows. You can open it by searching in the dash.
The command to install software is apt-get install package-name. You need to give it root privileges so you will have to prefix the command with sudo.
By default aptitude will fetch package from online repositories. But you can also make it install from a local file.
Another way for offline installation is to get the '.deb' package file of the software and run dpkg -i filename.deb.
Okay. So the idea is to download the software packages needed for ubuntu and use the installation tools provided to install them.
Ok For Ruby we have something called Ruby Version Manager or RVM. It allows you to have multiple versions of Ruby on your computer. I think that wont be necessary for you. But still we will go with RVM because of its ability to let you install ruby offline with ease.
Read more here: http://rvm.io/rvm/offline
As you might know, Rails is a gem of Ruby. In the above link you will find how to install Gems offline. Just download the Rails gem and install it using the local option of bundler. Ok I might have confused you with this paragraph. But you read the RVM documentation and you will understand.
If you do get an internet connection, there is an awesome tutorial (step by step) at DigitalOcean.com to guide you.
https://www.digitalocean.com/community/articles/how-to-install-ruby-on-rails-on-ubuntu-12-04-lts-precise-pangolin-with-rvm
I know its for Ubuntu 12.04. But you wouldnt face much problem.
Good luck. And learn about operating systems.
Installation of Ruby on Rails for Production server is pretty straight forward. Below are the relevant steps.
1.INSTALL THE NEEDED LIBRARIES
sudo apt-get install zlib1g zlib1g-dev build-essential openssl libssl-dev libmysqlclient18 libmysqlclient-dev libyaml-dev
2.DOWNLOAD AND INSTALL RUBY 1.9.3
sudo apt-get update
sudo apt-get install ruby1.9.3
Note you can install latest Ruby too.
3.INSTALL RAILS
sudo apt-get install ruby-dev
sudo apt-get install build-essential g++
sudo gem install railsconfigure rails application with nginx and unicorn
4.INSTALL SQLITE ADAPTER
sudo apt-get install libsqlite3-dev
If you passed all above steps without any ERROR, Now it's time to create a rails demo application OR SCP existing one and test it out.
Below is the steps to create new rails application
rails new demo
cd demo
uncomment therubyracer gem in Gemfile
sudo apt-get install build-essential g++
bundle install
rails g scaffold order name:string
rake db:create
rake db:migrate
Open config/routes file and uncomment root 'welcome/index' and replaced with 'orders/index'
$rm -rf public/index
That's all, Now run your Rails application.
Checkout http://railscasts.com/episodes/335-deploying-to-a-vps and search for "capistrano" to deploy. It's an art.
"It isn't connected to the internet so pretty much every tutorial I found hasn't worked"
You are way off the beaten path here. but if you can get your git repo to a machine that is connected to the internet, you can deploy to Heroku easy, and/or run capistrano from there.
