How to install bzip2 for Capistrano-db-tasks on Windows?

How to install bzip2 for Capistrano-db-tasks on Windows? - ruby-on-rails

I had an error with installation of bzip2 on Windows 7 for capistrano-db-tasks. I tried gem bzip2, gem bzip2-ruby and gem bzip2-ruby-rb20.
How to install it properly?

1) You need to install bzip2 libs. Download zipped libs from Bzip2 for Windows, Binaries. Unpack them to directory without spaces, say C:\GnuWin32\bzip2-1.0.5-bin. lib subdir should contain libbz2.a, libbz2.def, libbz2.dll.a. This path (C:\GnuWin32\bzip2-1.0.5-bin\lib) should be provided to --with-bz2-lib.
2) The package bzip2-ruby seems to have a not-fixed error yet according to the author github.com/brianmario (version.h is absent). So you can install bzip2-ruby-rb20 as he suggests.
gem install bzip2-ruby-rb20 -- --with-bz2-include="C:\GnuWin32\bzip2-1.0.5-bin\include" -- --with-bz2-lib="C:\GnuWin32\bzip2-1.0.5-bin\lib"
Should be done.
Now you can use commands as "cap db:pull".

How to install fluentd plugins on No network(offline)

I want to install fluent-plugin-route, but I don't know how.
i can't use gem install fluent-plugin-route because there's no internet.
Any ideas?

Suggestion: Build the package with rake and install it with gem
1) git clone "Your Repository"
2) bundle install
If you don't have bundler "gem install bundler"
3) bundle exec rake build
4) gem install pkg/xxx.gem (Location would be pkg folder)
Copy paste your gem via gem install --local as mentioned by DeeChok on your offline VM via gem produced on your online VM by following step 1-4

Download the gem and its dependencies (also gems)
Put them on the node/instance/vm
Change directory to where the gems are located
Run the below command:
gem install -N --conservative --minimal-deps --no-document --force --local *gem
N.B: You will have to have ruby installed. You can do that install ruby from source by following the steps here. You may need to install gcc, gcc-c++, openssl-dev(OR libel-dev on RHEL7) before hand.
Hope this helps :)

Ruby on rails.. rails server command, strange output? [duplicate]

I'm running a clean install of Ruby 2.2.1 on Windows 8.1 with DevKit. After the installation I run:
gem install rails
rails new testapp
cd testapp
rails server
leaving everything else at default.
The process fails at the last line when, instead of running the server, I get the error message
in 'require': cannot load such file -- 'nokogiri\nokogiri' (LoadError)
It happens every time and I've looked around and tried everything I found to fix it, but nothing so far has worked.
What is the problem here and how do I get a simple test Rails app to work?

Nokogiri doesn't support Ruby 2.2 on Windows yet. The next release will. See https://github.com/sparklemotion/nokogiri/issues/1256
Nokogiri doesn't support native builds (e.g. with devkit) on Windows. Instead it provides gems containing prebuilt DLLs.
There's a discussion which you may want to join or watch on the topic of devkit build support here: https://github.com/sparklemotion/nokogiri/issues/1190

First, uninstall the version of Nokogiri you currently have with:
gem uninstall nokogiri
Download Nokogiri 1.6.6.2 (x64) or Nokogiri 1.6.6.2 (x86)
Install this version locally using:
gem install --local C:\Users\$user$\Downloads\nokogiri-1.6.6.2-x64-mingw32.gem
or if you're running 32bit Ruby:
gem install --local C:\Users\$user$\Downloads\nokogiri-1.6.6.2-x86-mingw32.gem
The path may differ depending on where you downloaded the file to.
Try to start the server again using ruby bin\rails server, and it should work.

I got Nokogiri running with Ruby 2.2 on Windows 10 with a mix of Mike Dalessios and Julios answer:
Look for the latest version of Nokogiri in Nokogiri's github repo.
Run gem uninstall nokogiri.
Add gem "nokogiri", ">= 1.6.7.rc" to your Gemfile.
Run bundle install.
Run bundle update nokogiri if bundle has locked Nokogiri at some version.

Fix
Bundle install (gets Nokogiri files)
Browse to ruby_dir\lib\ruby\gems\2.2.0\gems\nokogiri-1.6.6.2\ext\nokogiri
Open extconf.rb
Add dir_config('iconv').any? or pkg_config('libiconv') to #376
Download MinGW64 & MSYS folders from Mega
Add them to PATH in Windows (remove Devkit path refs - it doesn't work)
Download libxml2,libxslt, iconv libraries (or here)
Run ruby extconf.rb --platform=ruby --n --use-system-libraries referencing downloaded libraries
Run make
Run make install
Steps
Bundle Install
First step is to bundle.
This will put the nokogiri gem on your machine without running the pre-packaged compiler (which mostly doesn't work in Windows).
This will show Nokogiri as installed:
Browse
Browse to the nokogiri folder, to find ext/nokogiri/extconf.rb:
Open extconf.rb
... and add dir_config('iconv').any? or pkg_config('libiconv') to #376
Standard Nokogiri installs "rely" on the libxml2 inclusion of iconv - we need to explicitly define it, otherwise iconv.h is missing errors will occur.
Add Toolchain
Don't use devkit for this - it doesn't work.
You need MinGW:
I have zipped my exact MinGW64 and MSYS64 folders on Mega (key: !FJtcq25l-QMsNltCxllMhc1IGqORvap8xv8gWxSUbDA):
Add to PATH
This gives access to gcc & make (both required):
Remove the devkit ref from your path, and add the following:
MINGW64_PATH/bin
MSYS64_PATH/bin
Download Libs
I have added the libs to Mega:
You will unzip them here:
All the libs are from this source.
Run extconf.rb
Once libs are on your system, you can run ruby extconf.rb to configure the build:
32bit
ruby extconf.rb --platform=ruby -N -- --use-system-libraries --with-xml2-dir=C:/Dev/Dependencies/Ruby/lib/nokogiri/32bit/libxml2-2.9.2-win32-x86 --with-xml2-include=C:/Dev/Dependencies/Ruby/lib/nokogiri/32bit/libxml2-2.9.2-win32-x86/include/libxml2 --with-iconv-dir=C:/Dev/Dependencies/Ruby/lib/nokogiri/32bit/iconv-1.14-win32-x86 --with-xslt-dir=C:/Dev/Dependencies/Ruby/lib/nokogiri/32bit/libxslt-1.1.28-win32-x86
64bit
#64
ruby extconf.rb --platform=ruby -N -- --use-system-libraries --with-xml2-dir=C:/Dev/Dependencies/Ruby/lib/nokogiri/64bit/libxml2-2.9.2-win32-x86_64 --with-xml2-include=C:/Dev/Dependencies/Ruby/lib/nokogiri/64bit/libxml2-2.9.2-win32-x86_64/include/libxml2 --with-iconv-dir=C:/Dev/Dependencies/Ruby/lib/nokogiri/64bit/iconv-1.14-win32-x86_64 --with-xslt-dir=C:/Dev/Dependencies/Ruby/lib/nokogiri/64bit/libxslt-1.1.28-win32-x86_64
make
This may create errors / warnings, as long as it says "Error 1 (ignored)", it should be okay.
Following that, use make install:
Then browse to your Rails installation and run rails s:
Explanation
To give context:
Ruby 2.2+ on Windows doesn't compile the extensions Nokogiri requires.
The extensions of a gem are the extra dependencies (libraries) it uses.
They are built when you install the gem:
Extensions
Lack of extensions is preventing Nokogiri from running.
Extensions exist in the ext folder of a gem (you can read about them here):
Mysql2,RMagick,PGSQL, Nokogiri etc all use extensions/libraries.
This is why - on Windows - you have to use custom switches (--with-opt-dir) when installing the gem. This gives Ruby / the shell / (cmd) the required lib / include directories required to build the gem's files (it's the equivalent of how PATH works).
On Linux/Mac, these directories are managed with the respective package managers (brew/apt-get). Windows does not have this, so you have to install the extensions manually.
Because Windows does not have a standard set of libraries, you have to download them yourself. You also have to build them yourself (which is tricky).
The fix for Nokogiri install is to use the right libraries and build tools to get the gem installed.
Build
The difference with Ruby 2.2+ is the gem will "install" without showing any exceptions. You think it has installed, only to find Rails does not load (hence the nokogiri/nokogiri.so error).
This means you have to make sure you have the files on your system, and run the compiler to install them.
The above documentation should show you how to do that.

Rails 3.1 app can't install sqlite3 gem because libraries are out of date

The latest SQLite3 library available on CentOS 5.6 and which is installed is version 3.3.6. It's my understanding that the sqlite3 gem needs version 3.6 or higher.
How do I get my app to work with SQLite3 without upgrading the library on my server? It's in a work environment and I'm simply not allowed to upgrade it.

You could compile a static library of the version of sqlite you require. Then install the sqlite3 gem with a reference to your new static library.
While I haven't tested this procedure, I could see the process being...
1. Download and extract the SQLite source in a new directory.
mkdir $HOME/sqlite3.7.7.1
cd $HOME/sqlite3.7.7.1
wget http://www.sqlite.org/sqlite-autoconf-3070701.tar.gz
tar -zxvf sqlite-autoconf-3070701.tar.gz
cd sqlite-autoconf-3070701
2. Configure, compile, and install.
./configure --disable-shared --enable-static --prefix=$HOME/sqlite3.7.7.1
make && make install
3.A. (option1) Install the SQLite gem with a reference to your new static lib.
gem install sqlite3 --with-sqlite3-dir=$HOME/sqlite3.7.7.1
3.B. (option2) Install via bundler. *Assuming sqlite3 has already been added to the Gemfile (thanks to Lester)
bundle config build.sqlite3 \
--with-sqlite3-include=$HOME/sqlite3.7.7.1/include \
--with-sqlite3-lib=$HOME/sqlite3.7.7.1/lib \
--with-sqlite3-dir=$HOME/sqlite3.7.7.1/bin
bundle install

The steps worked for me with one minor tweak. With gem 1.3.7 and rails 3.1.0 for step 3.A. I had to do:
gem install sqlite3 -- --with-sqlite3-dir=$HOME/sqlite3.7.7.1 --with-sqlite3-lib=$HOME/sqlite3.7.7.1/lib
the extra "--" in the middle allowed option to not be parsed by the gem file

This worked for me on a MacBook which had some different versions of sqlite3 that had accumulated over the years.
For me, the gem install was:
gem install sqlite3 -- --with-sqlite3-dir=/path/to/sqlite3/directory
In other words, I did only have to list the main sqlite3 development directory, but I did have to use the extra "--".
This allowed the installation of Rails 3.1 under Max OS X Lion

Why can't I install the SQLite gem?

I'm try to install the SQLite gem on a Fedora 9 Linux box with Ruby 1.8.6, Rails 2.2.2, gem 1.3, and sqlite-3.5.9. Here's the command I'm running and its results:
sudo gem install sqlite3-ruby
Building native extensions. This could take a while...
ERROR: Error installing sqlite3-ruby:
ERROR: Failed to build gem native extension.
/usr/bin/ruby extconf.rb install sqlite3-ruby
can't find header files for ruby.
Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2.4 for inspection.
Results logged to /usr/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2.4/ext/sqlite3_api/gem_make.out
gem_make.out just repeats what was already sent to the console. How can I install this gem?

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 and in order to do that it needs the C header files for the Ruby interpreter.
If you compile Ruby yourself, those header files will be installed automatically, however, in RedHat-ish systems, such header files are usually packaged in a seperate package, called <whatever>-dev. So, in this case you will need to install the ruby-dev package and possibly the libsqlite3-dev (Ubuntu) or sqlite-devel (Fedora) package as well.
However, you might be better off just installing your Operating System's pre-packaged libsqlite3-ruby package, that way all the dependencies are automatically satisfied.
(Note: all package names pulled out of thin air, might be different on your system.)

You probably need the ruby dev package. For Ubuntu you have to install ruby1.8-dev which includes the ruby header files. A quick google says that the yum package is ruby-devel. so run this:
sudo yum install ruby-devel

I faced problem installing sqlite3-ruby gem on my fedora 13 box.
It was fixed after sudo yum install sqlite-devel

When I had that problem:
gem install sqlite3 -v '1.3.9'
Building native extensions. This could take a while...
ERROR: Error installing sqlite3:
ERROR: Failed to build gem native extension.
For me worked, installing the "libsqlite3-dev" with:
apt-get install libsqlite3-dev

sudo apt-get install ruby-dev
Fixed it for me.

On Ubuntu 9 and 10 try:
sudo apt-get install ruby-dev
sudo apt-get install sqlite3-dev
Then run
gem install sqlite3

Run the following for Fedora OS:
yum install rubygem-sqlite3

On alpine, you need to install the sqlite-dev package.

I also faced this same issue, the problem is that your Linux installation requires the development libraries for SQLite3 to be installed in order to build the gem.
Here's how I fixed the issue
Open your terminal and run the following commands
sudo apt-get install sqlite3
sudo apt-get install libsqlite3-dev
And then try installing Sqlite3 gem again using this command
gem install sqlite3
That's all.
I hope this helps

Do you have all the source code required to build sqlite3-ruby? Gem is trying to compile some C code and cannot find the headers. You can probably use a fedora rpm for sqlite3-ruby (I don't use fedora, but I'm sure one exists) if you prefer to forgo compiling. Personally for ruby stuff, I prefer to use gem rather than a distro's packaging system.

I'm not really familiar with Fedora, but in Ubuntu when you are installing packages you have apt-get, and you have to install the build-essentials which includes gcc and other compilation tools for C. I would say that could be your issue, and you make look into how that can be install either using RPM or apt-get on Fedora.

I fixed the problem on my OLPC (Fedora 9) by installing 'gcc' oddly enough. It seems like it should have been one of those dev packages, but no.
Also, regarding the other packages, the suffix is "-devel", not "-dev", so make sure you get those ending right: "ruby-devel", "sqlite-devel"...
Once you get that installed, if you get errors about your gems being too old "< 1.3.1" when you try to run various rails scripts, eg: script/server or script/console, google "upgrade_rubygems" to fix that problem...
HTH...

Run "sudo yum install sqlite-devel" and then "gem install sqlite3". Had the same problem on my Fedora 15.

I had this same exact issue...instead of gem'ing the missing pieces I used synaptic on unbuntu.
The key package for me was libsqlite-ruby1.9.1 ... I documented my experience (for reference) with this error at :
Sqlite3-gem-error-during-bundle-install

I encountered this error while running bundle install after generating a react-rails app on Fedora 29. I was able to identify a suitable development package by running dnf search sqlite3, then installed it dnf install libsqlite3x-devel. This fixed it for me.
