前提：安裝的vagrant版本為vagrant_2.2.6_x86_64，
安裝的vagrantBox版本為VirtualBox-6.1.6-137129
輸入：vagrant up 命令時，提示如下信息
No usable default provider could be found for your system.
The easiest solution to this message is to install VirtualBox, which is available for free on all major platforms.
If you believe you already have a provider available, make sure it is properly installed and configured. You can see more details about why a particular provider isn't working by forcing usage with vagrant up --provider=PROVIDER, which should give you a more specific error message for that particular provider.
遇到上面的情況，說明需要指定一個提供者，
在指定一個提供者時，輸入：vagrant up --provider=virtualbox
等號后面的名稱根據提前裝載的virtualbox填寫
又提示下面的信息，說明vagrantbox的版本不再它顯示的版本中，
The provider 'centos/7' could not be found, but was requested to back the machine 'default'. Please use a provider that exists.
Vagrant knows about the following providers: docker, hyperv, virtualbox
vagrant up --provider=virtualbox The provider 'virtualbox' that was requested to back the machine 'default' is reporting that it isn't usable on this system. The reason is shown below:
Vagrant has detected that you have a version of VirtualBox installed that is not supported by this version of Vagrant. Please install one of the supported versions listed below to use Vagrant:
4.0, 4.1, 4.2, 4.3, 5.0, 5.1, 5.2, 6.0
A Vagrant update may also be available that adds support for the version you specified. Please check www.vagrantup.com/downloads.html to download the latest version.
然后在本地找plugin.rb、meta.rb文件進行修改
E:\HashiCorp\Vagrant\embedded\gems\2.2.6\gems\vagrant-2.2.6\plugins\providers\virtualbox\plugin.rb
修改這個文件，plugin.rb（文件增加紅色部分）
module Driver autoload :Meta, File.expand_path("../driver/meta", FILE) autoload :Version_4_0, File.expand_path("../driver/version_4_0", FILE) autoload :Version_4_1, File.expand_path("../driver/version_4_1", FILE) autoload :Version_4_2, File.expand_path("../driver/version_4_2", FILE) autoload :Version_4_3, File.expand_path("../driver/version_4_3", FILE) autoload :Version_5_0, File.expand_path("../driver/version_5_0", FILE) autoload :Version_5_1, File.expand_path("../driver/version_5_1", FILE) autoload :Version_5_2, File.expand_path("../driver/version_5_2", FILE) autoload :Version_6_0, File.expand_path("../driver/version_6_0", FILE) autoload :Version_6_1, File.expand_path("../driver/version_6_1", FILE) end
E:\HashiCorp\Vagrant\embedded\gems\2.2.6\gems\vagrant-2.2.6\plugins\providers\virtualbox\driver\meta.rb
修改**meta.rb這個文件，增加紅色的部分**
driver_map = { "4.0" => Version_4_0, "4.1" => Version_4_1, "4.2" => Version_4_2, "4.3" => Version_4_3, "5.0" => Version_5_0, "5.1" => Version_5_1, "5.2" => Version_5_2, "6.0" => Version_6_0, "6.1" => Version_6_1, }
在：E:\HashiCorp\Vagrant\embedded\gems\2.2.6\gems\vagrant-2.2.6\plugins\providers\virtualbox\driver
增加一個新文件，文件名稱：version_6_1.rb，內容如下：
require File.expand_path("../version_6_0", FILE)
module VagrantPlugins module ProviderVirtualBox module Driver # Driver for VirtualBox 6.1.x class Version_6_1 < Version_6_0 def initialize(uuid) super
@logger = Log4r::Logger.new("vagrant::provider::virtualbox_6_1") end end end end end
然后在執行：vagrant up --provider=virtualbox
