「r<-小技巧」Windows R 安装包显示无法锁定目录怎么搞

今天笔记本电脑装包反反复复出现下面错误：

Error in install.packages : ERROR: failed to lock directory ‘D:\Tool\R_Library’ for modifying
Try removing ‘D:\Tool\R_Library/00LOCK’

尝试下解决方案：

install.packages("Rcpp", dependencies = TRUE, INSTALL_opts = '--no-lock')

把 Rcpp 改成要装的包名。

不行的话把报错文件删了：

unlink("D:/Tool/R_Library/00LOCK", recursive = TRUE)
