Blogdown下载失败

Question

当我尝试用RStudio的packages面板安装blogdown包时，出现了这个错误。我想这是一些基本的东西，但我不知道它意味着什么！

> install.packages("blogdown")

  There is a binary version available but the source version is later:
         binary source needs_compilation
blogdown    0.6    0.7             FALSE

installing the source package ‘blogdown’

trying URL 'https://cran.rstudio.com/src/contrib/blogdown_0.7.tar.gz'
Warning in install.packages :
  cannot open URL 'https://cran.rstudio.com/src/contrib/blogdown_0.7.tar.gz': HTTP status was '502 Bad Gateway'
Error in download.file(url, destfile, method, mode = "wb", ...) : 
  cannot open URL 'https://cran.rstudio.com/src/contrib/blogdown_0.7.tar.gz'
Warning in install.packages :
  download of package ‘blogdown’ failed

谢谢你的帮助！

使用cran镜像服务有问题。对于cran.rstudio.com，您可以在这里跟踪服务状态：https://status.rstudio.com/

当您有类似的错误时，您可以尝试另一个镜像，例如，更改RStudio IDE全局选项中的repos或在调用install.packages或全局中更改选项repos。与options(repos = c(CRAN='<new-url>')‘
