我通过完成入门教程尝试学习Vagrant。但是，只有教程中的几个步骤已经无法正常工作，如教程中所述。具体来说，看起来Vagrant并不知道如何下载教程中使用的框。这是我到目前为止所做的：
查看是否安装了vagrant：
$ which vagrant
安装Vagrant：
$ sudo aptitude install vagrant
The following NEW packages will be installed:

试试vagrant getting started tutorial：
$ mkdir vagrant_getting_started && cd $_
$ vagrant init
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.
$ vagrant box add hashicorp/precise32
This command was not invoked properly. The help for this command is
available below.
Usage: vagrant box add <name> <url> [--provider provider] [-h]
--checksum VALUE Checksum
--checksum-type VALUE Checksum type
-c, --clean Remove old temporary download if it exists.
-f, --force Overwrite an existing box if it exists.
--insecure If set, SSL certs will not be validated.
--cacert certfile CA certificate
--cert certfile The client SSL cert
--provider provider The provider that backs the box.
-h, --help Print this help
根据此输出，我看起来需要指定一个可以从中下载框的URL。因此，根据教程，我搜索了Hashicorp's Atlas box catalog。我认为我找到了正确的资源https://atlas.hashicorp.com/hashicorp/boxes/precise32，但是这个资源没有提供可以从中获取框的URL。相反，它只是说vagrant up hashicorp/precise32 --provider virtualbox。所以我尝试了这个命令并得到了这个错误：
$ vagrant up hashicorp/precise32 --provider virtualbox
The machine with the name 'hashicorp/precise32' was not found configured for
this Vagrant environment.
在哪里找到应该在vagrant box add <name> <url>命令中使用的URL？我认为在Hashicorp的盒子目录中很容易找到它，但我没有在任何地方看到它。
以防这是有关我当前环境的有用信息：
$ vagrant box list -i
There are no installed boxes! Use `vagrant box add` to add some.
答案 0 :(得分：9)
我认为问题是你最终得到了一个相当旧版本的Vagrant - 1.4.3-1，而最新版本是1.7.2。您安装的存储库可能不再保持最新状态。
我建议您卸载当前的内容，然后重新安装Vagrant downloads中的最新内容。
更新：如果您在Linux上安装Vagrant（Debian或RPM格式打包），您肯定希望从Vagrant downloads下载，因为存储库中的软件包不是保持最新，并将很老。
对于Vagrant 1.7.2，框中添加帮助部分说明：
$ vagrant box add -h
Usage: vagrant box add [options] <name, url, or path>
The box descriptor can be the name of a box on HashiCorp's Atlas,
or a URL, or a local .box file, or a local .json file containing
the catalog metadata.
然后，您可以继续按照“使用入门”指南进行操作，并可以在Boxes documentation上阅读更多内容。
更新2 ：对于原始问题“我如何找到Box文件的URL？”，有两种情况：
来自HashiCorp的盒子现在托管在他们的Atlas service上：这些是用“hashicorp / precise32”或“ubuntu / trusty64”等简写代码识别的。我想有一个webservice或约定，其中vagrant命令行可以查询Atlas云，然后找到实际的下载URL。它们似乎并不公开，但您可以通过观察网络流量或查看流浪源来解决这个问题。
来自其他可能是公共或内部（公司）的项目的框：这些框通常带有直接指向.box文件的普通URL。您可以在Vagrantbox.es上看到这些示例。事实上，如果你在那里搜索'vagrantup'，你会看到很多原始的标准盒子及其URL。
答案 1 :(得分：7)
我不清楚为什么你不会只运行vagrant init hashicorp/precise32，因为它会处理这两个发现并将盒子添加到你的盒子注册表中。
但是，如果你真的想看看这个盒子来自何处，即使使用旧版本的vagrant，你也可以利用--debug标志，你会看到引擎盖下的此框的网址当前 https://atlas.hashicorp.com/hashicorp/boxes/precise32/versions/1.0.0/providers/virtualbox.box的输出。
回答这个问题（虽然不是这样推荐的）：
vagrant box add hashicorp/precise32 https://atlas.hashicorp.com/hashicorp/boxes/precise32/versions/1.0.0/providers/virtualbox.box
答案 2 :(得分：1)
使用：
~ » vagrant version
Installed Version: 2.0.1
Latest Version: 2.0.1
You're running an up-to-date version of Vagrant!
您只需发出一个curl请求即可获取数据。见下文：
