win7环境下，vagrant，在启动虚拟机的时候报错io.rb:32:in `encode': incomplete "\xC8" on GBK (Encoding::InvalidByteSequenceError)

描述：

　　这几天在windows环境上，部署了vagrant，在启动虚拟机的时候报错：

[c:\~]$ vagrant up

==> default: Matching MAC address for NAT networking...

解决过程：

　　找了好久，都没有说明白，后来在国外的github上看到了解决的方案。

My Solution

With the help of a non vagrant-related * solution, I solved the issue by changing the line  in "Vagrant\embedded\gems\gems\vagrant-2.0.1\lib\vagrant\util" as:

data << io.readpartial(READ_CHUNK_SIZE).encode('UTF-8', invalid: :replace, undef: :replace, replace: '?')

即修改源代码，说改就改：

1.找到D:/tools/HashiCorp/Vagrant/embedded/gems/2.2.5/gems/vagrant-2.2.5/lib/vagrant/util/io.rb文件，找到32行

data << io.readpartial(READ_CHUNK_SIZE).encode("UTF-8", Encoding.default_external)

2.将这行注释掉，下面加入参考github上的代码

              #data << io.readpartial(READ_CHUNK_SIZE).encode("UTF-8", Encoding.default_external)
              data << io.readpartial(READ_CHUNK_SIZE).encode('UTF-8', invalid: :replace, undef: :replace, replace: '?')

3.修改之后，重新执行命令vagrant up

[c:\~]$ vagrant up

==> default: Importing base box 'centos'...
==> default: Matching MAC address for NAT networking...
==> default: Setting the name of the VM: Sessions_default_1566958795239_49467
Vagrant is currently configured to create VirtualBox synced folders with
the `SharedFoldersEnableSymlinksCreate` option enabled. If the Vagrant
guest is not trusted, you may want to disable this option. For more
information on this option, please refer to the VirtualBox manual:

  https://www.virtualbox.org/manual/ch04.html#sharedfolders

This option can be disabled globally with an environment variable:

  VAGRANT_DISABLE_VBOXSYMLINKCREATE=

or on a per folder basis within the Vagrantfile:

  config.vm.synced_folder '/host/path', '/guest/path', SharedFoldersEnableSymlinksCreate: false

==> default: Preparing network interfaces based on configuration...

    default: shared folder errors, please make sure the guest additions within the
    default: virtual machine match the version of VirtualBox you have installed on
    default: your host and reload your VM.
    default:

顺利通过！
