软件包安装失败在Rstudio中，如何确定出了什么问题？

Question

我正在尝试在Rstudio中安装rmarkdown。安装失败，因为它试图安装到错误的文件夹，这是不存在的。为什么它试图安装到文件夹..Rprofile/win/3.2，尽管我已经将它配置为安装到R/win-library/3.2中？

如果不为install.packages指定lib参数，则会得到相同的错误。

> .libPaths()
[1] "c:/Users/ako/Documents/R/win-library/3.2" "C:/Program Files/RRO/R-3.2.1/library"    
> install.packages("rmarkdown",lib="c:/Users/ako/Documents/R/win-library/3.2")
trying URL 'https://mran.revolutionanalytics.com/snapshot/2015-07-01/bin/windows/contrib/3.2/rmarkdown_0.7.zip'
Content type 'application/zip' length 1310297 bytes (1.2 MB)

Error in install.packages : path[1]="c:\Users\ako\Documents\.Rprofile\win-library\3.2": The system cannot find the path specified

Update：libPaths正在发生一些奇怪的事情，更改libPaths现在不起作用：

> .libPaths()
[1] "c:/Users/ako/Documents/.Rprofile/win-library/3.2" "C:/Program Files/RRO/R-3.2.1/library"            
> file.exists("c:/Users/ako/Documents/R/win-library/3.2")
[1] TRUE
> .libPaths("c:/Users/ako/Documents/R/win-library/3.2")
> .libPaths()
[1] "c:/Users/ako/Documents/.Rprofile/win-library/3.2" "C:/Program Files/RRO/R-3.2.1/library"  

调试libPaths可以看到以下内容：

....
Browse[2]> 
debug: new <- Sys.glob(path.expand(new))
Browse[2]> new
[1] "c:/Users/ako/Documents/R/win-library/3.2"
Browse[2]> 
debug: paths <- unique(normalizePath(c(new, .Library.site, .Library), 
    "/"))
Browse[2]> c(new, .Library.site, .Library)
[1] "c:/Users/ako/Documents/R/win-library/3.2" "C:/PROGRA~1/RRO/R-32~1.1/library"        
Browse[2]> normalizePath(c(new, .Library.site, .Library), 
+ "/")
[1] "c:/Users/ako/Documents/.Rprofile/win-library/3.2" "C:/Program Files/RRO/R-3.2.1/library"  

因此，normalizePath将/R/替换为/..Rprofile/。是什么原因造成的？

通过将R、RRO和RStudio重新安装到不包含空格的文件夹中解决.
