The problem

In setting up the octopress environment, we need to install dependencies like this:

gem install bundler
bundle install

First line simply installs bundler (a Ruby dependency manager). The second line is where you might face problems:

bundle install

Install the dependencies specified in your Gemfile

Look at the Gemfile in your octopress folder, it looks like this:

source "https://rubygems.org"

group :development do
  gem 'rake', '~> 10.0'
  gem 'jekyll', '~> 2.0'
  gem 'octopress-hooks', '~> 2.2'
  gem 'octopress-date-format', '~> 2.0'
  gem 'jekyll-sitemap'
  gem 'rdiscount', '~> 2.0'
  gem 'RedCloth', '~> 4.2.9'
  gem 'haml', '~> 4.0'
  gem 'compass', '~> 1.0.1'
  gem 'sass-globbing', '~> 1.0.0'
  gem 'rubypants', '~> 0.2.0'
  gem 'rb-fsevent', '~> 0.9'
  gem 'stringex', '~> 1.4.0'
end

gem 'sinatra', '~> 1.4.2'

When I do ‘bundle install’:

$ bundle install
Fetching gem metadata from https://rubygems.org/........
Resolving dependencies...

Gem::RemoteFetcher::FetchError: SSL_connect returned=1 errno=0 state=SSLv3 read
server certificate B: certificate verify failed (https://rubygems.org/gems/rake-
10.4.2.gem)
An error occurred while installing rake (10.4.2), and Bundler cannot continue.
Make sure that `gem install rake -v '10.4.2'` succeeds before bundling.

It shows the gem ‘rake’ is missing. So I did as I was instrcucted to. I type gem install rake -v ‘10.4.2’ into command line, and execute. Again, I was told another gem missing. I kept doing this, until I found this is an endless procedure:

$ bundle install
Fetching gem metadata from https://rubygems.org/.......
Using rake 10.3.2
Using RedCloth 4.2.9
Using blankslate 2.1.2.4

Gem::RemoteFetcher::FetchError: SSL_connect returned=1 errno=0 state=SSLv3 read
server certificate B: certificate verify failed (https://rubygems.org/gems/timer
s-1.1.0.gem)
An error occurred while installing timers (1.1.0), and Bundler cannot continue.
Make sure that `gem install timers -v '1.1.0'` succeeds before bundling.

Something is very wrong with the execution of ‘bundle install’.

The solution

Until I found this post, I was hopelessly searching and learning Ruby gems and related things.

I fact, I just deleted 1 letter by changing source “https://rubygems.org” to source “http://rubygems.org” at line 1 of Gemfile in octopress folder.

Then, everything is fine:

I guess this is because my network security settings, but I do not know. If you are facing the same issue, I hope my solution helped. Or if you know the reason, please tell me by leaving a comment below. Thanks!
