Download all gems dependencies

问题

I want to install compass by downloading any required file and taking them to another machine without internet connection. I have downloaded the source package for compass and when I run gem on it in the non connected machine it complains about missing dependencies. Any solution?

回答1:

Thats exactly the problem I had.
After searching around a while I found a Solution who works using Bundler https://bundler.io/

Getting Gem with Dependencies:

Create a new Folder with a File named Gemfile in it.
Write a Source and the Gem you want to have the dependencys for into the File
Bsp:

source "http://rubygems.org"
gem 'rails', '3.2.1'
Open a Commandline at this Folder an Execute: bundle install
This should download and install all Dependencys
Execute the Command bundle list if you wanna see it
Execute the Command bundle package
This should create the Directory Structure vendor/cache
Inside the cache Directory are now all the Dependencys you need for your gem

Install Gem on Machine without internet connection:

Copy the cache Folder to the Machine
Open a Commandline inside the Cache Folder and execute gem install --local Gemname.gem
Bsp:

gem install --local rails-3.2.1.gem

I did

export GEM_HOME=.
export GEM_PATH=.
gem install --no-ri --no-rdoc --install-dir . <gem>

Hm. That's a little tough. gem dependency will show you dependencies for one gem, but it won't go all the way down the tree.

➔ gem dependency compass
Gem compass-0.10.5
  haml (>= 3.0.4, runtime)

Gem compass-0.10.6
  haml (>= 3.0.4, runtime)

➔ gem dependency haml   
Gem haml-3.0.21
  maruku (>= 0.5.9, development)
  yard (>= 0.5.3, development)

Gem haml-3.0.22
  maruku (>= 0.5.9, development)
  yard (>= 0.5.3, development)

Gem haml-3.0.23
  maruku (>= 0.5.9, development)
  yard (>= 0.5.3, development)

Gem haml-3.0.24
  maruku (>= 0.5.9, development)
  yard (>= 0.5.3, development)

"development" means it's only required if you are developing the gem itself. "runtime" means you need it to use it.

so in this case, the only dependency is haml. if it were a more complicated gem, i don't know a good way to generate the whole tree.
