【问题描述】：

我正在尝试根据环境将 slate 文档推送到 2 个不同的 S3 存储桶。但它抱怨 s3_sync 不是中间人的参数。

我已经使用 config.rb 提到了环境中的 S3 存储桶，但是当我运行 bundle exec middleman s3_sync --verbose --environment=internal 时仍然遇到上述问题

config.rb:

configure :internal do
  s3_sync.bucket                     = ENV['INTERNAL_DOCS_AWS_BUCKET'] # The name of the internal docs S3 bucket you are targeting. This is globally unique.
end

activate :s3_sync do |s3_sync|
  s3_sync.bucket                     = ENV['DOCS_AWS_BUCKET'] # The name of the S3 bucket you are targeting. This is globally unique.
  s3_sync.region                     = ENV['DOCS_AWS_REGION']     # The AWS region for your bucket.
  s3_sync.aws_access_key_id          = ENV['DOCS_AWS_ACCESS_KEY_ID']
  s3_sync.aws_secret_access_key      = ENV['DOCS_AWS_SECRET_ACCESS_KEY']
  s3_sync.prefer_gzip                = true
  s3_sync.path_style                 = true
  s3_sync.reduced_redundancy_storage = false
  s3_sync.acl                        = 'public-read'
  s3_sync.encryption                 = false
  s3_sync.prefix                     = ''
  s3_sync.version_bucket             = false
  s3_sync.index_document             = 'index.html'
  s3_sync.error_document             = '404.html'
end

错误：

捆绑器：加载失败命令：中间人 (/usr/local/bundle/bin/middleman) NameError: undefined local variable 或 #Middleman::ConfigContext:0x0000561eca099a40 的方法 `s3_sync'

【解决方案1】：

s3_sync 仅在 activate :s3_sync 块内定义。它在 configure :internal 块中未定义。

解决方案可能如下所示，使用 environment? 或 environment

activate :s3_sync do |s3_sync|
  s3_sync.bucket = if environment?(:internal)
                     ENV['INTERNAL_DOCS_AWS_BUCKET']
                   else
                     ENV['DOCS_AWS_BUCKET']
                   end
  s3_sync.region = ENV['DOCS_AWS_REGION']
  # ...
end
