安装R语言package（KEGG.db） 失败

Question

各位好！我用的R3.4，启动时界面显示错误，提示：

错误: 1:8: unexpected input
1: Path:C:\

使用source("https://bioconductor.org/biocLite.R")
biocLite("KEGG.db")
安装KEGG.db后显示如下提示：
错误: 1:8: unexpected input
1: Path:C:\
^
停止执行

The downloaded source packages are in
‘C:\Users\Administrator\AppData\Local\Temp\Rtmpe08K9A\downloaded_packages’
Error in if (file.exists(dest) && file.mtime(dest) > file.mtime(lib) && :
需要TRUE/FALSE值的地方不可以用缺少值
此外: Warning messages:
1: 运行命令'"D:/PROGRA~1/R-34~1.0/bin/x64/R" CMD INSTALL -l "D:\Program Files\R-3.4.0\library" C:\Users\ADMINI~1\AppData\Local\Temp\Rtmpe08K9A/downloaded_packages/KEGG.db_3.2.3.tar.gz'的状态是1
2: In install.packages(pkgs = doing, lib = lib, ...) :
installation of package ‘KEGG.db’ had non-zero exit status

请问有没有高人知道这是咋回事？
