尝试安装任何vagrant插件时遇到问题。安装vagrant插件时出现问题
vagrant plugin install vagrant-aws
vagrant plugin install vagrant-awsinfo
，我最终得到的错误是这样的：
Installing the 'vagrant-aws' plugin. This can take a few minutes...
Bundler, the underlying system Vagrant uses to install plugins,
reported an error. The error is shown below. These errors are usually
caused by misconfigured plugin installations or transient network
issues. The error from Bundler is:
Authentication is required for http://gems.hashicorp.com/.
Please supply credentials for this source. You can do this by running:
bundle config http://gems.hashicorp.com/ username:password
我是代理服务器的后面。不确定这个问题与它有什么关系。
