Installation

Prerequisites

You must have an active Alibaba Cloud OSS account. You must create an AccessKey ID and an AccessKey Secret.
If you want more information about OSS service and want to activate the OSS service, log on OSS Product Homepage to learn more.
If you have not created an AccessKey ID and an AccessKey Secret, go to Alibaba Cloud Access Key Management to create an AccessKey.

Install SDK with gem directly:

gem install aliyun-sdk

If the website https://rubygems.org is inaccessible, use the image source provided by Taobao.

gem install aliyun-sdk --clear-sources --source https://ruby.taobao.org

You can also install SDK by using Bundler. Initially, add the following content to the Gemfile of your app:

gem 'aliyun-sdk', '~> 0.3.0'

Run the following command:

# (Optional). Use the image source provided by Taobao 
bundle config mirror.https://rubygems.org https://ruby.taobao.org
bundle install

Note: https://ruby.taobao.org is the complete image of rubygems.org and automatically synchronizes with the official source. You can access https://ruby.taobao.org if rubygems.org is inaccessible.

Dependencies

Ruby 1.9.3 and later
Windows, Linux, or OS X system that supports Ruby

Note:

Some gems on which the SDK depends are local extensions, and you must install ruby-dev to compile locally extended gems.
The environment for running the SDK-dependent gem (nokogiri) for processing XML must have the zlib library.

Linux

The following method is used to install the preceding dependencies through Ubuntu in Linux:

sudo apt-get install ruby ruby-dev zlib1g-dev

The installation methods for various Linux releases (each with a package management tool) are similar.

Windows

Access RubyInstaller to download RubyInstaller. Double-click the installer to install the tool. Select “Add Ruby Executables to Your PATH” during the installation process.

Note: Download RubyInstaller 2.1 or an earlier version. RubyInstaller 2.2 cannot be installed due to Issues.
Access RubyInstaller to download the development kit. Make sure you select the right version. The downloaded kit is a compressed package. First create a folder named RubyDev in the C:\ root directory, and decompress the package to the folder.
Press the shortcut key Windows+R, input cmd, and press Enter to open the CLI. Then run the following commands:
```
 cd C:\RubyDev
 ruby dk.rb init
 ruby dk.rb install
```
If “config.yml configuration error” is displayed during the last step “install”, use the text editor to open the C:\RubyDev\config.yml file and modify the file content as follows:
```
 ---
 - C:/Ruby21
```
Save the config.yml file and continue ruby dk.rb install. “Ruby21” is the Ruby installation directory, which must be specified according to the actual name. Close the CLI once the operation is completed.
Press the shortcut key Windows+R, input cmd, and press Enter to open the CLI. Run the following commands:
```
 gem install aliyun-sdk
```
When installation is completed, input irb to open the Ruby interactive CLI, and input require 'aliyun/oss'. The SDK is successfully installed if “true” is displayed.

OS X

OS X has Ruby installed by default. To facilitate proper usage and management, we recommend you to install a development version.
Run xcode-select --install on your terminal to install “Xcode command line tools”. If installation fails, you can manually download and install the tools (see the steps to download).
Download Xcode command line tools from Apple’s Developer Center using your Apple ID. Make sure that your selected version matches your system version. After download, double-click the dmg file to load the file. Double-click the installation program in the dialog box to install the tools. Enter your system password during the installation process.

Run the following command on your terminal to install Brew:

 ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Run the following command on your terminal to install Ruby:
```
 brew install ruby
 exec $SHELL -l
```
Run the following command on your terminal to install SDK:
```
 gem install aliyun-sdk
```
Run the following command on your terminal to check the installation status of SDK.
```
 irb
 > require 'aliyun/oss'
 => true
```
