I'm trying to install sqlite3-ruby on Cygwin with gem install sqlite3-ruby -v x.x.x and I get the following error:
Building native extensions. This could take a while...
ERROR: Error installing sqlite3-ruby:
ERROR: Failed to build gem native extension.

Does anyone know how to install sqlite3 for Ruby on Rails on Cygwin. As I understand it the SQLite RubyGem isn't actually a *Ruby*Gem, it's a "*C*Gem", IOW it's written in C. This means it has to be compiled and linked to the Ruby interpreter when you install it, so any help?
So this isn't a complete solution as I don't have a windows box and cygwin handy but the error message suggests that the linux utility fdatasync can't be found.
The tools linux man page can be found here
http://linux.die.net/man/2/fdatasync
Maybe find out if you have fdatasync installed correctly and try again.
I ran into this issue just now – the first time I wanted to install a Ruby gem
on my new Cygwin 64-bit system.
As I understand it the SQLite RubyGem isn't actually a RubyGem, it's a
"CGem", IOW it's written in C. This means it has to be compiled and linked
to the Ruby interpreter when you install it.
Cygwin actually provide a pre-compiled package which installs the sqlite3
gem files including the sqlite3_native.so linked library file. The name of
the package is ruby-sqlite3 and you can install it using Cygwin’s Setup.exe.
I personally like to use apt-cyg
when possible (not always) so I installed the package using:
apt-cyg install ruby-sqlite3
This package installs the appropriate gem files as can be seen by running
cygcheck -l ruby-sqlite3:

There are 10's of questions are already tagged on this issue but none resolved.
Kindly help me to identify whats missing and why the error coming.
i386-mingw32 is a mountain of pain that'll never be fully supported, when I spent time on Windows I used to use a VirtualBox VM with ubuntu installed which shares a folder with the Windows host. I would edit the files with netbeans in windows and run the code in putty, the VM would basically be headless.
I actually did a lot of real work that way. If you want to do a "Hello World" rails app - OK - good luck even with that. How about an online development environment such as https://c9.io/ ?
But if you want to work, not just play around, set yourself up with an Ubuntu VM at the very least, or work in Ubuntu/MacOS at the very best.
Try this out:
Why don't you download the json .gem file from rubygems.org and install it directly using command
gem install json-x.x.x.gem
I am trying to setup a ruby on rails environment on my mac in order to start using the RubyMine IDE.
I have used homebrew, rbenv and all other required libraries in order to install ruby/rails - however when I sudo gem install rails the install fails due to :

I really hope somebody can help me as I am quite a noob to RonR and I feel like things have gotten messy directory/permission wise,
Thank you.
Let's take a quick look at a small part of the error that you have provided us.
zlib is missing; necessary for building libxml2
It's trying to tell you that you do not have zlib, so let's get it. Since you said you're using a Mac, I would install a package manager like Homebrew. Try doing brew install zlib to install this package.
Additionally, if you're starting out learning Ruby, regardless of what platform you are using, it might be helpful to use something like rbenv or rvm to manage different versions of Ruby and the gems that go along with those versions. You will run into less permissions issues (e.g. having to run gem install as a privileged user), some of which may be easy to solve, but some of which may send you down a rabbit hole for a few hours.
I cloned my code from git to my Windows machine and when I run bundle install, I am getting this error:

it is showing:

Please help.
I had this same issue myself until I finally stumbled upon the answer on Stackoverflow here and here.
Basically you need to follow these steps:
Install DevKit. Since I used RailsInstaller to install Ruby on Rails on my laptop, it was already included in the default directory ‘C:\Serever\RailsInstaller\DevKit‘. Otherwise, find the .exe at the RubyInstallers downloads.
Install ImageMagick-6.9.5-9-Q16-x86-dll.exe from imagemagick.org. It seems that rmagik2.16 only supports ImageMagick 6, not ImageMagick 7.
Make sure that you install the correct version of ImageMagick x86 or x32. If you are unsure what ruby version you have install try this command: ruby -e "puts 1.size". It print 4 if x86 and 8 if x64. answer from here
Check the following options on the install screen (more info on the redmine website) :
[v] Add application directory to your system path
[v] Install development headers and libraries for C and C++
Setup in windows environment variables the PATH variable to include the path to ImageMagick. In my case: C:\Server\ImageMagick\. Make sure it is the first variable in the variables list, or you may encounter an “Invalid drive specification” error when extconf.rb tries to identify the ImageMagick version.
cd C:\YourRubyProject. Example: C:\Server\htdocs\dev-ruby\redmine.
Set CPATH and LIBRARY_PATH environment variables to point respectively to ImageMagick installation directory include and lib subdirectories (so the DevKit will find them at build time)
Open C:\Serever\RailsInstaller\DevKit\msys.bat. More details here
Run gem install rmagick --platform=ruby -- --with-opt-lib=C:/Server/ImageMagick/lib --with-opt-include=C:/Server/ImageMagick/include. Adjust paths as necessary for your project.
Finally, run bundle install, or if necessary bundle update
Note: for those that are looking to install redmine in xampp follow this tutorial. If you get stuck on installing the rmagick lib, return here to this answer and follow the provided steps.
I am doing a bundle install and all of the gems work fine except JSON when it get to the JSON gem I receive this error.

Any idea on what could be causing this error?
You are working with Windows, so the RubyInstaller Development Kit may help you:
http://rubyinstaller.org/add-ons/devkit/
The devkit installs a C-compiler (and some other stuff) to compile C-written parts.
Install it and try again to install the gem - perhaps with option --platform=ruby.
Details can be found at https://github.com/oneclick/rubyinstaller/wiki/Development-Kit
That's because this gem using a piece of code written on C. For working properly you need c compiler installed on your machine. As a way, try to use json_pure written on pure Ruby
I'm not an expert in ROR, but the JSON installation issue which I got while installing Redmine was resolved by doing the following:
Create a make.bat at D:\LANGS\MinGW\bin
Keep this directory in the PATH
Edit the above make.bat and add a line, D:\LANGS\MinGW\msys\1.0\bin\make.exe
What I realized is, mingw32-make.exe never worked, but 'D:\LANGS\MinGW\msys\1.0\bin\make.exe' worked.
Note: My MinGW installation is under D:\LANGS\ . Please make the changes accordingly in your specific installation.
Yes, install the development kit. Also, You will need to run a few command lines to install it (not just simply download and run).
Download it, run it to extract it somewhere (permanent). Then cd to it, run ruby dk.rb init and ruby dk.rb install to bind it to ruby installations in your path.
A guide for that is here:

I was trying to run an OpenSource project which requires ferret to be installed. While installing it using gem install ferret, it's giving this error ->

So, I tried installing nmake (nmake15.exe), but I couldn't find it. It does not install on Windows 7. How can I install ferret?
Some Ruby gems use native extensions, which means they're partially written in C or C++. These gems need to be compiled during installation, which is easy if you're on Linux. Also, most of these gems provide binaries for Windows. However, some gems, like ferret's, don't and still need to be compiled during installation.
The good news is that a toolkit called DevKit makes it easy to build native extensions on Windows. Follow the installation guide here: https://github.com/oneclick/rubyinstaller/wiki/Development-Kit
nmake is similiar to the make Unix tool used for compiling C and other languages. Some Ruby extensions that use C code need to be compiled.
nmake comes with Visual Studio (C++, C#, and VB). Alternatively, download nmake.exe by itself. Install either and your problem should clear up.
Execute Below command and its works
gem install ferret --platform=mswin32
