为Windows生成R包时出现奇怪的错误

在我的一台电脑上,当我构建任何R包时,我会得到以下致命错误

* checking for file 'forecast/DESCRIPTION' ... OK
* preparing 'forecast':
* checking DESCRIPTION meta-information ... OK
* cleaning src
* removing junk files
* checking for LF line-endings in source and make files
* checking for empty or unneeded directories
* building binary distribution
WARNING: some HTML links may not be found
Error in setwd(owd) : cannot change working directory
 ERROR
* installation failed

但同样的软件包在我的另一台电脑上也能很好地编译。我对造成这种情况的原因一无所知。还有人看到类似的东西吗?

使用Windows XP、R2.10.1、RTools 2.10。
