我试图从一本关于Scrapy的书中学习。作者使用由vagrant和docker构建的测试环境。环境需要遵循本书中的教程。我对这两种技术都一无所知，但从昨天起就一直在努力让一切运转起来。经过几个小时的搜索，并尝试各种各样的事情（比如拔出我的指甲），我完全没有进展。
我试图包含任何可能相关的信息。很抱歉某些数据格式不佳。我是新来的。此外，我不得不从一些代码嵌入链接中删除'http'，因为stackoverflow不会让我发布太多的超链接。
版本号为：vagrant 1.8.5，docker 1.12.1，ubuntu 16.04
当我进入包含vagrant文件的目录并运行'vagrant up --no-parallel'时，我得到了臭名昭着的“系统找不到可用的默认提供程序”，错误。
'vagrant box list'返回'没有安装的盒子！使用vagrant box add添加一些。'
'vagrant global-status'返回“此计算机上没有活动的Vagrant环境！或者，您没有销毁并重新创建使用较旧版本的Vagrant启动的Vagrant环境。” （我的操作系统是一个全新的安装）
“docker info”返回：

还有一个名为Vagrant.dockerhost的文件，该文件在Vagrantfile中引用：
# Set if you are behind proxy
#proxy_url = "http://user:pass@proxy.com:8080/"
Vagrant.configure("2") do |config|
if !defined?(proxy_url) || proxy_url.nil? || proxy_url.empty?
# No proxy setup necessary.
else
# Setup proxies
ENV['http_proxy'] = proxy_url
ENV['https_proxy'] = proxy_url
end
config.vm.define "docker-provider"
config.vm.box = "lookfwd/scrapybook"
# Setting up ports

[9200] + # ES
[6379] + # Redis
[3306] + # MySQL

(6800..6803).to_a + # Scrapyd
[21] + (30000..30009).to_a + # Spark
[]).each do |port|
config.vm.network "forwarded_port", guest: port, host: port
end
# Set the mem/cpu requirements
config.vm.provider :virtualbox do |vb|
vb.memory = 2048
vb.cpus = 4
vb.name = "docker-provider"
vb.check_guest_additions = false
end

解决方法是安装VirtualBox

如果您只需要在没有VM Host的情况下使用docker，请将force_host_vm = TRUE更改为FALSE（force_host_vm = FALSE）
