R:install.packages错误
我只是想简单地安装一个软件包,整个事情就是FUBAR。本周早些时候工作得很好。没有接触防火墙设置或任何东西,并且尝试在两个独立网络上的两台独立计算机上同时安装“readxl”和“dplyr”(dplyr只是为了测试问题是否是readxl软件包),问题仍然存在。在我的手机上尝试了我的家庭互联网(wifi和硬线)以及移动热点。如何让它恢复正常,快速、轻松地下载和安装软件包R:install.packages错误,r,R,我只是想简单地安装一个软件包,整个事情就是FUBAR。本周早些时候工作得很好。没有接触防火墙设置或任何东西,并且尝试在两个独立网络上的两台独立计算机上同时安装“readxl”和“dplyr”(dplyr只是为了测试问题是否是readxl软件包),问题仍然存在。在我的手机上尝试了我的家庭互联网(wifi和硬线)以及移动热点。如何让它恢复正常,快速、轻松地下载和安装软件包 > install.packages("readxl") Warning in install.packages :

@Kevin,我使用chooseCRANmirror选择了密歇根州的CRAN mirror,但install.packages仍然默认为原始的坏镜像

我的默认CRAN镜像也已更新,但即使在重新启动RStudio后似乎也没有效果。
*****临时修复*****
必须运行以下代码:
a) 切换默认CRAN镜像后
及
b) 在每节课开始时
options(repos = getOption("repos")["CRAN"])
options(repos = getOption("repos")["CRAN"])
我遇到了同样的问题,整天都在解决它。我尝试了几种不同的CRAN镜子,最后这一种起了作用: install.packages('readxl',dependencies=TRUE,repos='')
下载立即发生。看起来像是一个bug,RStudio选项中有一个额外的镜像,指向一个不稳定的目标。据报道,RStudio已经意识到了这个问题,确认这是一个bug,并将在下一版本中修复 必须首先更改默认的CRAN镜像,然后在每次会话开始时仍必须运行临时解决方案
options(repos = getOption("repos")["CRAN"])
options(repos = getOption("repos")["CRAN"])

谢谢你帮我缩小这个问题,凯文。试着增加超时限制(可能300而不是100)
选项(超时=300)尝试其他下载镜像。这一个看起来像是移动了或是向下移动了。在特定的会话中,我如何做到这一点?我尝试将我的Rprofile CRAN设置更改为密歇根州的镜像,重新启动R,然后使用install.packages运行“repos=getOption(“repos”),但仍然遇到错误。它看起来仍然指向原始镜像。我应该做些别的事吗?抱歉,不太熟悉后端设置选项。再次感谢。请尝试运行'chooseCRANmirror(),并选择最近的一个。Kevin,在尝试您的建议后编辑OP。使用临时解决方案更新OP。看起来这是一个bug,在RStudio选项中烘焙了一个额外的镜像,指向一个不稳定的目标。据报道,RStudio已经意识到了这个问题,确认这是一个bug,并将在下一版本中修复。临时解决方案必须在每次会话开始时运行。相关帖子:凯文,谢谢你在缩小问题范围方面的帮助。嗨,麦克,谢谢你的建议。不幸的是,对我来说,它仍然默认为最初的坏CRAN mirror,然后仅在近2分钟内第一次多次失败后才检查提供的回购。这是一个RStudio错误。谢谢你的意见。
