# Installing Ruby on Windows

* The [Chocolatey Package Manager](http://chocolatey.org/) makes installing Ruby a breeze.  Think of it as NuGet for your machine.  To install it, follow the instructions on [their website](http://chocolatey.org/).
* Certain Chocolatey packages might not work with older versions of Powershell so update it to the latest version.

    ```
    $ choco install powershell
    ```

* Install Ruby.

    ```
    $ choco install ruby
    ```

* Restart your shell to refresh the environment variables.
* Install Ruby DevKit.

    ```
    $ choco install ruby2.devkit
    ```

* Check that ruby is installed by running the following. Note that your version may be slightly different:

    ```
    $ ruby --version
    ruby 2.1.5p273 (2014-11-13 revision 48405) [x64-mingw32]
    ```

## Troubleshooting

When installing Ruby DevKit, it should automatically register itself with the
installed ruby version.  However, you may need to configure Ruby DevKit manually
by running the following.

```
$ cd \tools\DevKit2
$ echo "- C:/tools/ruby215" >> config.yml
$ ruby dk.rb install --force
```
