Installation problems - not sure if fatal or not

[samfullman]

I am running a Mac OSX Yosemite with Virtual Box, Vagrant version 1.8.1

I followed instructions on the readme.MD file and got the following error when I ran /var/www/bootstrap-advanced.sh (sorry for size but I wanted to be detailed):

Running composer as root/super user is highly discouraged as packages, plugins and scripts cannot always be trusted
Installing yiisoft/yii2-app-advanced (dev-master a34ba1e1bced7acd4edd7cc20eb9dab0aa725c4e)

• Installing yiisoft/yii2-app-advanced (dev-master master)
  Downloading: 100%

Created project in /var/www/yii2app.dev
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Problem 1
- yiisoft/yii2 2.0.x-dev requires bower-asset/jquery.inputmask ~3.2.2 -> no matching package found.
- yiisoft/yii2 dev-master requires bower-asset/jquery.inputmask ~3.2.2 -> no matching package found.
- yiisoft/yii2 2.0.8 requires bower-asset/jquery 2.2.@stable | 2.1.@stable | 1.11.@stable -> no matching package found.
- yiisoft/yii2 2.0.7 requires bower-asset/jquery 2.2.@stable | 2.1.@stable | 1.11.@stable -> no matching package found.
- yiisoft/yii2 2.0.6 requires bower-asset/jquery 2.1.@stable | 1.11.@stable -> no matching package found.
- Installation request for yiisoft/yii2 >=2.0.6 -> satisfiable by yiisoft/yii2[2.0.6, 2.0.7, 2.0.8, dev-master, 2.0.x-dev].

Potential causes:

• A typo in the package name
• The package is not available in a stable-enough version according to your minimum-stability setting
  see https://getcomposer.org/doc/04-schema.md#minimum-stability for more details.

ERROR: Site yii2app.dev does not exist!

• Reloading web server config apache2 [ OK ]
  PHP Warning: require(/var/www/yii2app.dev/vendor/autoload.php): failed to open stream: No such file or directory in /var/www/yii2app.dev/yii on line 14

All Done!

Now add the ip/domain to your hosts file if you didn't already. A little help:
echo '33.33.33.34 yii2app.dev www.yii2app.dev admin.yii2app.dev' | sudo tee -a /etc/hosts

Access your new sites http://yii2app.dev http://admin.yii2app.dev
