Could not load OpenSSL.
https安全协议和http普通之间定问题， 修改Gemfile文件， 把https:改为http  搞定

Gem files will remain installed in /tmp/bundler20140620-3966-vx09po/sqlite3-1.3.9/gems/sqlite3-1.3.9 for inspection.
需要安装sqlite3  如下：
sudo apt-get install sqlite3 

An error occurred while installing sqlite3 (1.3.9), and Bundler cannot continue.Make sure that `gem install sqlite3 -v '1.3.9'` succeeds before bundling.

安装sqlite3时少了这一步：
apt-get install libsqlite3-dev 

好了  搞定手工：   进目录运行：bundle install 结果如下：
