setInternet2无法连接窗口 [英] setInternet2 cannot connect windows

问题描述

在工作中我通常必须设置 setInternet2（use = TRUE）选项才能访问用于更新包等的曲目。但是在他们将win explorer更新为版本之后8这似乎不再有效。这是在使用和不使用setInternet2选项的情况下尝试安装e1071后的输出。

At work I usually have to set the setInternet2(use=TRUE) option in order to access cran for updating packages etc.. However after they updated win explorer to version 8 this doesnt seem to work anylonger. This is the output after trying to install e1071 both with and without the setInternet2 option invoked.

是否有任何想法可以解决这个问题？

Any ideas if this can be remedied?

推荐答案

与网络管理员交谈。让他们检查IE8的连接设置是否配置正确。它们也可能阻止某些类型的流量，无论IE8在您的工作场所使用哪个端口都是默认的。

Speak with your network admins. Get them to check that IE8's connection settings are configured properly. It's also possible that they are blocking some kinds of traffic whatever port is the default for IE8 to use at your workplace.
