老师您好， 我想merge 两个文件 但是出现以下问题 该怎么解决好啊？ 谢谢老师
merge 1:1 id year using C:\Users\toshiba\Desktop\innovation\0_analysis\0_data\1_wide_long.dta

(pathsplit() in lmatabase, compiled by Stata 11.2, is too new to be run by this version of Stata and
so was ignored)
          fullfilename():  3499  pathsplit() not found
                 <istmt>:     -  function returned error
r(3499);
