Visual Studio2017-生产力电动工具

Question

是否可以在没有互联网连接的计算机上为Visual Studio 2017安装生产力工具？

当我运行ProductivityPowerPack2017.vsix文件时，出现错误。

在日志文件中，我发现了这一点：

`(...)  System.AggregateException: One or more errors occurred. ---> System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException:` An existing connection was forcibly closed by the remote host. 

我相信这是因为我的机器的互联网连接受到限制（带有某些被阻止的URL）。

那么他们是安装Power Tools的一种方法吗？我需要Visual Studio 2017的流程编辑器。
