与以下问题类似:

Error when using install_github: 'exdir' does not exist

我似乎无法使用 devtools 软件包从github安装软件包,在我尝试的所有软件包上得到以下错误(slidify,rCharts,rga,magrittr等...):

Error in unzip(src, list = TRUE) : 
  zip file 'C:/Users/.../Rtemp\RtmpGIlGBA/master.zip' cannot be opened
In addition: Warning messages:
1: In unzip(src, exdir = target, unzip = getOption("unzip")) :
    error 1 in extracting from zip file

我已经将临时目录更改为可写的地方,以防这是问题所在:

write("TMP = 'C:/Users/.../Rtemp' \n
           TMPDIR = 'C:/Users/.../Rtemp' \n
           TEMP = 'C:/Users/.../Rtemp'", 
            append = TRUE,
            file = file.path(Sys.getenv('R_USER'), '.Renviron'))
    readRenviron(".Renviron")

但无济于事 . 我还有 setwd() 到其他地方并通过直接从github获取zip文件来检查 unzip() 是否存在问题:

temp <- tempfile()
download.file("https://github.com/ramnathv/slidifyLibraries/archive/master.zip",temp)
unzip(temp)

这似乎工作正常,我已经使用 build() 等安装了包...但它 notinstall_github() 一样方便 . 有任何想法吗?

这是我的 sessionInfo()
