Vagrant 错误：找不到提供者“aws”

Question

我正在使用 Vagrant 1.6.5 并尝试部署到 Amazon AWS。我可以成功部署到 DigitalOcean，但使用 AWS 时出现错误：

The provider 'aws' could not be found, but was requested to
back the machine 'default'. Please use a provider that  
exists.

我已经验证了 aws 插件已安装，

$ vagrant plugin list
vagrant-aws (0.5.0)
vagrant-digitalocean (0.7.0)
vagrant-login (1.0.1, system)
vagrant-share (1.1.1, system)

当我用谷歌搜索这个错误时，我得到的唯一建议是添加

vagrant.require_plugin 'vagrant-aws'

到 Vagrantfile 的开头。然而，这并不能解决错误，流浪者说它无论如何都被弃用了。

我真的被困在这个问题上，我不知道下一步该怎么做。以下是完整的错误消息，以防万一。

Answer 1

这是解决方案，以防有人搜索此问题。我卸载了 vagrant-aws 插件，然后重新安装：

vagrant plugin uninstall vagrant-aws
vagrant plugin install vagrant-aws

这解决了问题。
