有參照之前closed 的issue但還是一樣。 Perl is deprecated. Please use regexp instead Warning message: In file.rename(file.path(system.file(package = "swirl"), "Courses", : 無法將檔案 '/Users/bigtreehouse/Library/R/3.2/library/swirl/Courses/wush978-DataScienceAndR-df043e2' 重新命名為 ' /Users/bigtreehouse/Library/R/3.2/library/swirl/Courses/DataScienceAndR' ，原因是 'Directory not empty'
