Faraday::Adapter::NetHttpPersistent 缺少依赖项：无法加载此类文件 -- net/http/persistent

如何解决Faraday::Adapter::NetHttpPersistent 缺少依赖项：无法加载此类文件 -- net/http/persistent

具有持久 HTTP 调用的最新版 azure-storage-common 2.0.2 失败并出现以下错误：

missing dependency for Faraday::Adapter::NetHttpPersistent: cannot load such file -- net/http/persistent

呼叫是 create_block_blob。

已指定适当的依赖项：

gem 'faraday_middleware','1.0.0',{require: false}
gem 'net-http-persistent','4.0.0',{require: false}
gem 'azure-storage-common','2.0.2',{require: false}
gem 'azure-storage-blob','2.0.1',{require: false}

require 'azure/storage/blob'

是的，我可以看到 net-http-persistent 被捆绑。

我尝试将：require 'net/http/persistent' 放在这里，但没有帮助。同样的错误。

有什么指点吗？

编辑：

抱歉我没说清楚。我正在使用捆绑程序。并且 net-http-persistent 已捆绑。

我将 require 'net/http/persistent' 放在每个函数调用的前面，它仍然返回此错误，即使 require 语句返回 true 表示模块已加载。>

解决方法

我首先通过以下方式安装 azure blob 存储包：

gem install azure-storage-blob

然后，我使用下面的代码，它似乎工作正常：

require "openssl"
require "securerandom"
require "rbconfig"

# Require the azure storage blob rubygem
require "azure/storage/blob"

$stdout.sync = true

# This sample application creates a container in an Azure Blob Storage account,# uploads data to the container,lists the blobs in the container,and downloads a blob to a local file.
def run_sample
    is_windows = (RbConfig::CONFIG["host_os"] =~ /mswin|mingw|cygwin/)

    # Create a BlobService object
    blob_client = Azure::Storage::Blob::BlobService 

    begin

        # Create a BlobService object
        account_name = "yourstorageaccountname"
        account_key = "xxxxxx=="

            blob_client = Azure::Storage::Blob::BlobService.create(
            storage_account_name: account_name,storage_access_key: account_key
        )

        # Create a container
        container_name = "quickstartblobs" + SecureRandom.uuid
        puts "\nCreating a container: " + container_name
        container = blob_client.create_container(container_name)
        
        # Set the permission so the blobs are public
        blob_client.set_container_acl(container_name,"container")

        # Create a new block blob containing 'Hello,World!'
        blob_name = "QuickStart_" + SecureRandom.uuid + ".txt"
        blob_data = "Hello,World!"
        puts "\nCreating blob: " + blob_name
        blob_client.create_block_blob(container.name,blob_name,blob_data)

        # List the blobs in the container
        puts "\nList blobs in the container following continuation token"
        nextMarker = nil
        loop do
            blobs = blob_client.list_blobs(container_name,{ marker: nextMarker })
            blobs.each do |blob|
                puts "\tBlob name: #{blob.name}"
            end
            nextMarker = blobs.continuation_token
            break unless nextMarker && !nextMarker.empty?
        end

        # Download the blob

        # Set the path to the local folder for downloading
        if(is_windows)
            local_path = File.expand_path("~/Documents")
        else 
            local_path = File.expand_path("~/")
        end

        # Create the full path to the downloaded file
        full_path_to_file = File.join(local_path,blob_name)

        puts "\nDownloading blob to " + full_path_to_file
        blob,content = blob_client.get_blob(container_name,blob_name)
        File.open(full_path_to_file,"wb") {|f| f.write(content)}

        puts "\nPaused,press the Enter key to delete resources created by the sample and exit the application "
        readline()

    rescue Exception => e
        puts e.message
    ensure
        # Clean up resources,including the container and the downloaded file
        blob_client.delete_container(container_name)
        File.delete(full_path_to_file)
    end
end
