∞RVM in offline mode

This is only rough description of the process, not all the steps need to work right away, feel free to propose fixes here: rvm offline source.

∞Installing RVM offline

1. Choose the version of RVM you wish to deploy from: https://github.com/rvm/rvm/tags
2. Download the rvm tarball: curl -sSL https://github.com/rvm/rvm/tarball/stable -o rvm-stable.tar.gz
3. Create and enter rvm directory: mkdir rvm && cd rvm
4. Unpack it: tar --strip-components=1 -xzf ../rvm-stable.tar.gz
5. Install rvm: ./install --auto-dotfiles
   • use --help to get the options
   • sudo password may be required depending on the type of install
6. Load rvm: source ~/.rvm/scripts/rvm
   • if --path was specified when instaling rvm, use the specified path rather than '~/.rvm'

∞Download Ruby, rubygems and yaml

1. Download ruby
   • Find tar.bz2 version at: https://ftp.ruby-lang.org/pub/ruby/ (check sub-directories)
   • Download with curl: : curl -sSL https://ftp.ruby-lang.org/pub/ruby/ruby-2.2.0.tar.bz2 -o ruby-2.2.0.tar.bz2
   • Must use ruby source archive with .tar.bz2 extension! The versions at https://www.ruby-lang.org/en/downloads/ are tar.gz, change it tar.bz2 before downloading.
2. Download rubygems
   • Find version at: https://github.com/rubygems/rubygems/tags
   • Download with curl: curl -sSL http://production.cf.rubygems.org/rubygems/rubygems-2.4.6.tgz -o rubygems-2.4.6.tgz
3. Download yaml (required by rvm)
   • Download from rvm.io with curl: curl -sSL http://pyyaml.org/download/libyaml/yaml-0.1.6.tar.gz -o yaml-0.1.6.tar.gz
4. Save these packages for offline use by storing them in the rvm archive folder $rvm_path/archives/ by default
   • An alternate archive folder can be specified in the .rvmrc file
   • sample usage: echo rvm_archives_path=/path/to/tarballs/ >> ~/.rvmrc

∞Install dependencies

1. Disable automatic dependencies ("requirements") fetching: rvm autolibs read-fail
2. Manually download and install dependencies
   • Get the list of dependencies: rvm requirements
   • Consult your system manual how to manually download and install the required software

∞Installing Ruby

1. Clean default gems: echo "" > ~/.rvm/gemsets/default.gems
2. Clean global gems: echo "" > ~/.rvm/gemsets/global.gems
3. Install Ruby: rvm install 2.2.0 --rubygems 2.4.6 (this may require sudo password for autolibs)
   • Install any other Ruby versions you want similarly
4. Set default Ruby version: rvm use 2.2.0 --default

∞Installing gems

There are multiple ways to install gems, you could download the gem files, but the best way seems to be Bundler: http://bundler.io/bundle_package.html

Example installing rails gem:

∞Online

1. Create a (fake) project directory: mkdir gems; cd gems
2. Install bundler: gem install bundler
3. Create Gemfile: bundle init
4. Add rails to it: echo "gem 'rails'" >> Gemfile
5. Install all gems: bundle install
6. Get gem files: bundle package
7. Package project: tar czf gems.tgz .
8. Download bundler from https://rubygems.org/gems/bundler the Download link

∞Offline

1. Create a (fake) project directory: mkdir gems; cd gems
2. Unpack gems: tar xzf gems.tgz
3. Install bundler: gem install bundler-1.8.3.gem
4. Install gems: bundle install --local
