想安装forecasting这个安装包，下到本地以后总是无法安装，请教各位大神这是怎么回事
Error in read.dcf(file.path(pkgname, "DESCRIPTION"), c("Package", "Type")) :
  无法打开链结
此外: Warning messages:
1: In unzip(zipname, exdir = dest) : 从zip文件中抽取1时出了错
2: In read.dcf(file.path(pkgname, "DESCRIPTION"), c("Package", "Type")) :
  无法打开压缩文件'forecasting_1.11.tar.gz/DESCRIPTION'，可能是因为'No such file or directory'
>

另：这个package很久了，只能下到本地安装
