如何诊断“无法创建套接字"? [英] How do I diagnose "unable to create socket"?

问题描述

当我在帮助搜索框中输入字符串时，RStudio 突然给我这个错误:

Suddenly RStudio is giving me this error when I enter a string on the help search box:

starting httpd help server ...Error in tools::startDynamicHelp() : unable to create socket

当我在控制台输入以下内容时出现同样的错误:

I get the same error when I enter the following on the console:

> ?grep

我已更新到 RStudio 的当前版本，并且正在运行 R 的当前版本.我在 R 本身中尝试了相同的命令，但没有问题.

I have updated to the current version of RStudio and was running the current version of R. I tried the same command in R itself and there's no problem.

也许是巧合，当我尝试让 RStudio 更新软件包时，我收到以下消息:

Maybe coincidentally, when I try to get RStudio to update packages, I get this message:

Warning: unable to access index for repository http://cran.rstudio.com/bin/windows/contrib/3.1
Warning: unable to access index for repository http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/3.1

以下是 RStudio 在诊断报告文件中提供的内容:

Here is what RStudio provides in a diagnostics-report file:

我卸载 R 和 RStudio，然后重新安装，问题没有消失.现在，当我启动 RStudio 时，我得到:

I have UNINSTALLED R and RStudio and then re-installed and the problem doesn't go away. Now when I launch RStudio, I get:

Error in tools::startDynamicHelp() : unable to create socket

推荐答案

嗯，一个答案就是尝试任何事情——即使是看起来很遥远的事情.事实证明，这个神秘且非常恼人的错误只发生在 64 位版本的 R 中(在 RStudio 中)，而不是 32 位版本！以下是解决问题的方法:

Well, one answer is to just try anything -- even something that appears quite remotely possible. It turns out that that this mysterious and very irritating bug only happens in the 64-bit version of R (within RStudio), not the 32-bit version! Here's how to fix the problem:

选择32位版本即可解决！RStudio 太棒了，它的帮助系统不工作真是太可惜了！

Selecting the 32-bit version solves it! RStudio is SO great, it is a huge bummer for its help system to not be working!
