I have installed a GEM called "Ziya" using the terminal in Mac OSx. However, when I open the application using the Netbeans, it says that the GEM cannot be found.
If I install Ziya using the GEM manager, I get the following error and the GEM doesn't get installed,
WARNING: Installing to ~/.gem since /Library/Ruby/Gems/1.8 and
/usr/bin aren't both writable.
WARNING: You don't have /Users/snehal/.gem/ruby/1.8/bin in your PATH,
gem executables will not run.
UPDATE: The GEM is installed in my machine. But Netbeans can't recognize it.
Thanks,
Snehal
do u have the appropriate permission to write to the folders? try to do a
sudo gem install Ziya
and see if it works =)

Being really new to Ruby/Rails, and after attempting to resolve the issue myself this weekend I'm making an attempt to seek advice here.
I have a complete Ruby/Apache/Passenger setup done on FreeBSD, and I'm trying to accomplish the task of using Windows as a Ruby development environment.
So far:
Ruby is installed, v2.0.0p0 (2013-02-24) [x64-ming32]
Rails is installed, v.3.2.12
I have the Ruby dev kit installed and registered.
I have the sqlite3 dll/exe copied to the Ruby "bin" folder (which is also in my path using the "Start Command Prompt with Ruby" console.)
I can start a rails server successfully, and continuing with the http://guides.rubyonrails.org/getting_started.html tutorial to 3.3.
">rake db:create" tells me:
Please install the sqlite3 adapter: gem install activerecord-sqlite3-adapter (
sqlite3 is not part of the bundle. Add it to Gemfile.)
which I have no "understanding" of. Trying to install activerecord-sqlite3-adapter gives me a "Could not find a valid gem..."
">gem install sqlite3" returns:
Building native extensions. This could take a while...
ERROR: Error installing sqlite3:
ERROR: Failed to build gem native extension.
D:/Development/Ruby200-x64/bin/ruby.exe extconf.rb
checking for sqlite3.h... *** extconf.rb failed ***
Right now I'm stuck at the point where I don't even know what state my Ruby on Windows installation is in. I'm trying to follow the main Rails tutorial and it doesn't specify any of these issues (probably because Ruby on Windows seems to be a natural pain for a lot of people.)
What am I missing?!? I'm just trying to install sqlite3 for Ruby on Windows, seems simple right?
If I do ">rais db" the SQLite shell is presented:
SQLite version 3.7.15.2 2013-01-09 11:53:05
Similar questions with steps that do not resolve my issue:
Installing SQLite 3.6 On Windows 7
Even though the question has been answered, I want to post my research to help others. I found a lot of information online, but being a Ruby newbie I had a tough time following all. The basic answer comes from the following post https://github.com/luislavena/sqlite3-ruby/issues/82 with instructions by "paulwis" on how to properly install sqlite3 for ruby 2.0.0-p0 and some comments on https://github.com/rails/rails/issues/10150 . So here it is:
Install the Ruby Devkit for your setup (DevKit-mingw64-64-4.7.2-20130224-1432-sfx.exe for me since I use a x64 machine)
Download and extract the autoconf package from Sqlite.org
Run msys.bat (it is inside the ruby devkit root folder)
cd into the path where you downloaded the sqlite source (for example: "cd /c/dev/sqlite3" for path "c:\dev\sqlite3" if you are new to MSYS/MINGW32)
Run "./configure"
Run "make"
Run "make install"
Get the sqlite3 gem again, this time specifying the platform and the path to the newly compiled binaries:
gem install sqlite3 --platform=ruby -- --with-sqlite3-include=[path\to\sqlite3.h] --with-sqlite3-lib=[path\to\sqlite3.o]
For example:
gem install sqlite3 --platform=ruby -- --with-sqlite3-include=/c:/dev/sqlite3/ --with-sqlite3-lib=/c:/dev/sqlite3/.libs/
(from the paths given in step 4)
Check the Gemfile.lock of your rails app and make sure that it points to the correct sqlite3 version. Mine was "sqlite3 (1.3.7-x86-mingw32)" and manually changed it to "sqlite3 (1.3.7-x64-mingw32)". Removing the platform also works: "sqlite3 (1.3.7)".
This is an old thread, but still relevant.
For us it was as simple as editing the Gemfile and adding a specific version for sqlite.
gem 'sqlite3', '~> 1.3.13'
I was able to install sqlite3 with ruby2.0.0 on win XP32 with following command:
c:\>gem install sqlite3 --platform=ruby -- --with-sqlite3-dir=C:/distr/sqlite --with-sqlite3-include=C:/distr/sqlite
Folder C:/distr/sqlite contains following files
shell.c
sqlite3.c
sqlite3.h
sqlite3ext.h
sqlite3.def
sqlite3.dll
So, basically I've extract sqlite-amalgamation-3071602.zip and sqlite-dll-win32-x86-3071602.zip to C:/distr/sqlite.
HEADS UP
You still need to put copy of sqlite3.dll and sqlite3.def somewhere to PATH. IMHO it's best to keep sqlite3 binaries in ruby's bin folder.
#!/usr/bin/env sh
mkdir c:/sqlite3x86
wget -P c:/sqlite3x86 http://packages.openknapsack.org/sqlite/sqlite-3.7.15.2-x86-windows.tar.lzma
cd c:/sqlite3x86
bsdtar --lzma -xf c:/sqlite3x86/sqlite-3.7.15.2-x86-windows.tar.lzma
gem install sqlite3 --platform=ruby -- --with-opt-dir=c:/sqlite3x86
cd c:/
rm -rf c:/sqlite3x86
For windows,
go to C:/Ruby25-x64/lib/ruby/gems/2.5.0/gems/sqlite3-1.3.13-x64-mingw32/lib/sqlite3.rb
and make sure
require "sqlite3" instead of native
Get the fat binary from here
https://ci.appveyor.com/project/MSP-Greg/sqlite3-ruby/build/3/job/hhk6ie8gdo545svr/artifacts
and
gem install c:\path\to\downloaded_gem.gem
You should follow this procedure:
gem install bundler
(add in Gem file_)
gem 'sqlite3', ' < 1.4'(add in Gem file_)
then run:
install bundler
I figured I'd put in an answer -- from the comments, for posterity's sake. The issue seemed to be that I grabbed a new version of Ruby/Rails (for Windows) that was not compatible "yet" with SQLite3.
I downgraded to 1.9.x and was able to things running.
The easiest way to get set up for Ruby on Rails on a Windows machine is by using the RailsInstaller, which automatically installs and configures sqlite3 for you. One step.
http://railsinstaller.org/en
I want to install ruby on rails in offline mode (i.e. without internet connection). So I downloaded railsinstaller-3.2.0.exe from http://railsinstaller.org/en and installed it. By the end, I had ruby installed but in order to have rails installed I ran
gem install rails
and faced these errors: (meaning command needs internet connection)
ERROR: Loading command: install (ArgumentError)
unknown encoding name - CP720
ERROR: While executing gem ... (NoMethodError)
undefined method 'invoke_with_build_args' for nil:NilClass
I mean is there any solution like downloading gems with another computer connected to internet and then copying files in the proper location in the installed directory of gems.
Please help me if you have any idea.
As said in a comment, it's a gem (lib) dependency issue.
You might want to look into installing the bundler gem library to manage dependencies for you, with bundler you would just have to run, bundle install and it would download all the required gems for you including any gem dependencies.
You can install bundler simply, just run
gem install bundler
Then in your rails project directory, just run bundle install.
Often to run a project (like rails for example) you might have to start it with
bundle exec rails start
To install Gem's on a non-internet connect computer you might want to refer to this answer on just that problem.
This is the website where you can find all available ruby gems. Ruby
gems download. Find the one you are interested and download it.
Then move the gem in a directory of your choice and cd into that from
the command prompt. I am using C:/ruby193/bin/pony-1.4.gem
Let's say that the gem we are interested in is the pony gem (smtp
email).
Just type gem install pony-1.4.gem
and you should get it installed manually unless you have a restricted
acc with not adequate administrative privileges.
You can also refer to the official documentation on the matter.
As the question states - where does the gem install?
Is it installing within the app directory that I'm working in (i.e. user/sites/sample_app)? Or is it being installed on my computer? If the latter where exactly?
Thanks!
gem install process
first download gem and save desktop
1.next step open command prompt and set location that means c:/desktop> gem install --local "gemname"
2.next step com to rails consoler and type $bundle install --local.
3. type the gem name on gem list
I have two questions:
Where do you install your ruby?
Did you use RVM or rbenv?
Now I will explain your question using my situation as an example.
I use RVM to manage rubies on my mac os.
now the ruby install in path
/Users/pin/.rvm/rubies/ruby-2.1.1
and these will be a gems directory under .rvm path. In this directory,
/Users/pin/.rvm/gems
there are many gems group, I have a group named
ruby-2.1.1#global
which is used by the default ruby version.
This is a directory and there will be a gems directory under it.
/Users/pin/.rvm/gems/ruby-2.1.0/gems
In this directory, you will find all of the gems you installed using cmd
bundle install
If you don't use ruby version management tools like rvm or rbenv, you may find the gems
around your ruby path. If you still can't find them, you can post the details of how you
install the rubies and other system configs, so that we can discuss here.
If you are using rvm then its get installed in
/home/user/.rvm/gems/ruby-version#global/ or /home/user/.rvm/gems/ruby-version/
If you are using specific gemset for gems then
/home/user/.rvm/gems/ruby-version#gemset_name/
If you want to know where gem is installed use gem which *gem_name* e.g.:
gem which rails
If you installed your gems with bundle install use bundle show *gem name* e.g.:
bundle show rails
Gems
If you use gem install x, you're adding the gem to the local ruby version on your system. This is a system-wide installation, and will be stored in your rubylib/ruby/gems dir:
The install command downloads and installs the gem and any necessary
dependencies then builds documentation for the installed gems.
Bundler
Using the bundle install command (when you have a Gemfile & use bundler), you basically tell bundler to install the gems relative to your specific applicaiton:
Bundler makes sure that Ruby can find all of the gems in the Gemfile
(and all of their dependencies). If your app is a Rails 3 app, your
default application already has the code necessary to invoke bundler.
If it is a Rails 2.3 app, please see Setting up Bundler in Rails 2.3.
For example, if you have a Rails 3.2 app, and a Rails 4.1 app on your system, using bundler allows you to instal the dependencies (gems) for each app independently
If you use gem install x, it will install the gem for all applications, and should only be used for things like rmagick and the database connection gems

Do i need to make any other changes/ setups to install this gem with my gemfile using bundle install?
Also I actually need an earlier gem '2.5.2' but the win32 specific version of that gem does not seem to available, is there any way to get it?
I need to do this development on windows for the moment so I can switch to any other OS for the moment. Also since this is a legacy app I am working on, I will need to stick with rmagick and can't switch to any other solution.

Please help!
Many thanks.
Hey have you tried installing Devkit, for installing gems with native extensions on windows.
Try the steps in the following link, and check whether the Devkit has been installed in your path variable, try opening a new command shell and install the gems.
http://doelsengupta.blogspot.in/2010/10/unable-to-download-gem-with-native.html
all the best!!
I kept having this problem but was finally able to get around it using the following solution from #Martin Cohen - after modifying the gemspec file as he has suggested and rebuilding it, i was able to successfully install rmagick gem using bundle install...
