R在最新的Windows 10更新后将无法运行

问题描述

我已经更新了Windows，R无法运行，因此R studio也无法运行。当我运行R GUI时，它会冻结并且没有响应。我已允许免除铬进入防火墙

我正在使用Windows Insider程序，并且刚刚更新为

Windows 10 Home,Insider Preview

Evaluation copy.Build 20190.rs_prerelease.200807-1609

请注意，R GUI会先冻结然后关闭，因此问题可能出在R GUI而非R Studio。

我在R studio上遇到以下错误。

Try:

ERR_CONNECTION_REFUSED

Cannot Connect to R
RStudio can't establish a connection to R. This usually indicates one of the following:

The R session is taking an unusually long time to start,perhaps because of slow operations in startup scripts or slow network drive access.
RStudio is unable to communicate with R over a local network port,possibly because of firewall restrictions or anti-virus software.
Please try the following:

If you've customized R session creation by creating an R profile (e.g. located at ~/.Rprofile),consider temporarily removing it.
If you are using a firewall or antivirus software which guards access to local network ports,add an exclusion for the RStudio and rsession executables.
Run RGui,R.app,or R in a terminal to ensure that R itself starts up correctly.

解决方法

此问题已通过Windows 10 Insider Preview内部版本 20201 （于2020年8月26日在Dev通道中发布）修复。前两个内部版本缺少64位API R的预建版本所必需。

相同的问题。回滚到以前的版本可以解决该问题。

我认为这与Windows图形功能的更新有关。微软在build 20190 changelog中说过：

改进的图形设置体验

虽然这不是一项新功能，但我们已根据客户反馈进行了重大更改，这将使客户的图形设置体验受益。我们做了以下改进：

我们更新了“图形设置”，以允许用户指定默认的高性能GPU。

我们已经更新了“图形设置”，以允许用户基于每个应用程序选择特定的GPU。
