我跟随RailsCast＃347（http://railscasts.com/episodes/347-rubber-and-amazon-ec2）在Amazon EC2上部署我的应用程序。
完成所有步骤后，当我尝试执行命令cap rubber:create_staging时，向我显示此错误/Users/juampi/.rvm/gems/ruby-2.2.1/gems/rubber-3.2.0/lib/rubber/cloud/aws/base.rb:75:in before_create_instance＆＃39 ;: undefined method instance_alias' for #<Rubber::Configuration::InstanceItem:0x007f9fce9704f8> (NoMethodError)

# REQUIRED All known cloud providers with the settings needed to configure them
# There's only one working cloud provider right now - Amazon Web Services
# To implement another, clone lib/rubber/cloud/aws.rb or make the fog provider
# work in a generic fashion
#
cloud_providers:
aws:
# REQUIRED The AWS region that you want to use.
#
# Options include
# ap-northeast-1 # Asia Pacific (Tokyo) Region
# ap-southeast-1 # Asia Pacific (Singapore) Region
# ap-southeast-2 # Asia Pacific (Sydney) Region
# eu-west-1 # EU (Ireland) Region
# sa-east-1 # South America (Sao Paulo) Region

# REQUIRED The amazon keys and account ID (digits only, no dashes) used to access the AWS API
#
access_key: #myaccesskey
secret_access_key: #Mysecretaccesskey
account: #myaccount
# REQUIRED: The name of the amazon keypair and location of its private key
#
# NOTE: for some reason Capistrano requires you to have both the public and
# the private key in the same folder, the public key should have the
# extension ".pub". The easiest way to get your hand on this is to create the
# public key from the private key: ssh-keygen -y -f gsg-keypair > gsg-keypair.pub
#
key_name: gsg-keypair
key_file: "#{Dir[(File.expand_path('~') rescue '/root') + '/.ec2/*' + cloud_providers.aws.key_name].first}"
# OPTIONAL: Needed for bundling a running instance using rubber:bundle
#
# pk_file: "#{Dir[(File.expand_path('~') rescue '/root') + '/.ec2/pk-*'].first}"
# cert_file: "#{Dir[(File.expand_path('~') rescue '/root') + '/.ec2/cert-*'].first}"
# image_bucket: "#{app_name}-images"
# OPTIONAL: Needed for backing up database to s3
# backup_bucket: "#{app_name}-backups"
# OPTIONAL: Define a VPC to deploy to. The alias can be thought of as a
# unique Rubber-specific Id. If vpc_alias and vpc_addr are absent, Rubber
# will instead assume we're deploying to EC2 Classic
# vpc_alias: "#{app_name}_#{Rubber.env == 'production' ? 'production' : 'development'}"
# vpc_cidr: 10.0.0.0/16
# VPCs will typically have two subnets - one for instances that need a
# direct internet connection (load balancers, etc.), and one for instances
# that don't (database servers, app servers, etc.). At the very least,
# we'll need a public subnet. Rubber will detect the instance's private_nic
# configuration, and auto-create a subnet if appropriate. Any instances on
# the public subnet will need the following configuration. It is also
# important to note that AWS VPC Subnets are availability zone-specific,
# meaning you probably want to specify an availability zone for your
# instance. You will also have to specify a different subnet_cidr for each
# availability zone, since subnets cannot overlap.
# private_nic:
# subnet_cidr: '10.0.0.0/24'
# gateway: public
# For a private subnet, you will need to configure a nat_gateway instance in
# the public subnet so that machines can still reach the outside world for
# things like software updates. After configuring a NAT gateway, you can
# set up a separate private subnet. You will also need to set your :gateway
# Capistrano configuration value to the full hostname of the nat gateway in
# order to communicate with instances on private subnets. Instances which
# are on a private subnet will need the following configuration
# private_nic:
# subnet_cidr: '10.0.1.0/24'
# gateway: "#{rubber_instances.for_role('nat_gateway').first.instance_id}"
# REQUIRED: the ami and instance type for creating instances
# The Ubuntu images at http://old.alestic.com/ work well
# Ubuntu 14.04.1 Trusty instance-store 64-bit: ami-92f569fa
#
# m1.small or m1.large or m1.xlarge
image_type: t2.micro
image_id: ami-60b6c60a
# OPTIONAL: Provide fog-specific options directly. This should only be used if you need a special setting that
# Rubber does not directly expose. Since these settings will be passed directly through to fog, we can't make any
# guarantee about how they work (if fog renames an attribute, e.g., your config will break). Please see the fog
# source code for the option names.
# fog_options:
# EBS I/O optimized instance
# EBS-optimized instances deliver dedicated throughput between Amazon EC2 and Amazon EBS, with options
# between 500 Mbps and 1000 Mbps depending on the instance type used.
# Read more and make sure that your image_type supports ebs_optimized function at: http://aws.amazon.com/ec2/instance-types/
# ebs_optimized: false
# OPTIONAL: EC2 spot instance request support.
#
# Enables the creation of spot instance requests. Rubber will wait synchronously until the request is fulfilled,
# at which point it will begin initializing the instance, unless spot_instance_request_timeout is set.
# spot_instance: true
#
# The maximum price you would like to pay for your spot instance.

#
# If a spot instance request can't be fulfilled in 3 minutes, fallback to on-demand instance creation. If not set,
# the default is infinite.
# spot_instance_request_timeout: 180
digital_ocean:
# REQUIRED: The Digital Ocean region that you want to use.
#
# Options include
# New York 1
# Amsterdam 1
# San Francisco 1
# New York 2
# Amsterdam 2
# Singapore 1
#
# These change often. Check https://www.digitalocean.com/droplets/new for the most up to date options.

# Optionally enable private networking for your instances.
# This is currently only supported in New York 2.
private_networking: true

#
# If you need to port between forms, load the rails console then:
# Rubber.instances.save(location)
# where location is one of the allowed forms for this variable
#
# instance_storage: "file:#{Rubber.root}/config/rubber/instance-#{Rubber.env}.yml"
# OPTIONAL: Where to store a backup of the instance data
#
# This is most useful when using a remote store in case you end up
# wiping the single copy of your instance data. When using the file
# store, the instance file is typically under version control with
# your project code, so that provides some safety.

# instance_storage_backup: "storage:#{cloud_providers.aws.backup_bucket}/RubberInstances_#{app_name}/instance-#{Rubber.env}-#{Time.now.strftime('%Y%m%d-%H%M%S')}.yml"

# source_security_group_name, source_security_group_owner_id
# ip_protocol, from_port, to_port, cidr_ip

# OPTIONAL: The default security groups to create instances with
assigned_security_groups: [default]
roles:
web:
assigned_security_groups: [web]
web_tools:
assigned_security_groups: [web_tools]
# OPTIONAL: Automatically create security groups for each host and role
# EC2 Classic doesn't allow one to change what groups an instance belongs to after
# creation, so it's good to have some empty ones predefined. EC2 with VPC, however,
# does allow changing security groups after instance creation and allows far fewer
# security groups per instance, so you shouldn't enable this setting if using VPC.
auto_security_groups: false
# OPTIONAL: Automatically isolate security groups for each appname/environment
# by mangling their names to be appname_env_groupname
# This makes it safer to have staging and production coexist on the same EC2
# account, or even multiple apps. NB: due to the security group limits per instance
# in EC2 with VPCs, this option should only be enabled if you're using EC2 Classic.
isolate_security_groups: false
# OPTIONAL: Prompts one to sync security group rules when the ones in amazon
# differ from those in rubber
prompt_for_security_group_sync: true
# OPTIONAL: A list of CIDR address blocks that represent private networks for your cluster.
# Set this to open up wide access to hosts in your network. Consequently, setting the CIDR block
# to anything other than a private, unroutable block would be a massive security hole.
private_networks: [10.0.0.0/8]
# OPTIONAL: The packages to install on all instances
# You can install a specific version of a package by using a sub-array of pkg, version
# For example, packages: [[rake, 0.7.1], irb]
packages: [postfix, build-essential, git-core, libxslt-dev, ntp]
# OPTIONAL: The package manager mirror to use for installation of primary packages (i.e., those not explicitly
# sourced from a different repository). If not specified, whatever mirror configured by your server image
# will be used.
#
# Note that Ubuntu has a special URL that can be used to auto-select the mirror based upon geoip. To use
# it, specify 'mirror://mirrors.ubuntu.com/mirrors.txt' as the value.
# package_manager_mirror: 'mirror://mirrors.ubuntu.com/mirrors.txt'
# OPTIONAL: The command used to identify your particular OS version. This will be used for configurations
# in Rubber templates that are parameterized by OS version (e.g., package lists). If not specified, Ubuntu
# will be assumed.
os_version_cmd: 'lsb_release -sr'
# OPTIONAL: gem sources to setup for rubygems
# gemsources: ["https://rubygems.org"]
# OPTIONAL: The gems to install on all instances
# You can install a specific version of a gem by using a sub-array of gem, version
# For example, gem: [[rails, 4.2.1], bundler]
gems: [bundler, [rubber, "#{Rubber.version}"]]
# OPTIONAL: A string prepended to shell command strings that cause multi
# statement shell commands to fail fast. You may need to comment this out
# on some platforms, but it works for me on linux/osx with a bash shell
#
stop_on_error_cmd: "function error_exit { exit 99; }; trap error_exit ERR"
# OPTIONAL: The default set of roles to use when creating a staging instance
# with "cap rubber:create_staging". By default this uses all the known roles,
# excluding slave roles, but this is not always desired for staging, so you can
# specify a different set here
#
# staging_roles: "web,app,db:primary=true"
# Auto detect staging roles
staging_roles: "#{known_roles.reject {|r| r =~ /slave/ || r =~ /^db$/ }.join(',')}"
# OPTIONAL: Lets one assign amazon elastic IPs (static IPs) to your instances
# You should typically set this on the role/host level rather than
# globally , unless you really do want all instances to have a
# static IP
#
# use_static_ip: true
# OPTIONAL: Specifies an instance to be created in the given availability zone
# Availability zones are sepcified by amazon to be somewhat isolated
# from each other so that hardware failures in one zone shouldn't
# affect instances in another. As such, it is good to specify these
# for instances that need to be redundant to reduce your chance of
# downtime. You should typically set this on the role/host level
# rather than globally. Use cap rubber:describe_zones to see the list
# of zones
# availability_zone: us-east-1a
# OPTIONAL: If you want to use Elastic Block Store (EBS) persistent
# volumes, add them to host specific overrides and they will get created
# and assigned to the instance. On initial creation, the volume will get
# attached _and_ formatted, but if your host disappears and you recreate
# it, the volume will only get remounted thereby preserving your data
#
# hosts:
# my_host:
