本人使用的是stata16,stata用的不久，前几天为了一个新的外部命令直接把自己本来ado下面的plus文件删掉了，替换成了连玉君老师分享的plus文件。之后又下载了另一个新命令ppmlhdfe及其他pakages,程序报“the following files already exist and are different”，然后就把列出来的文件删掉了，继续安装完成后检查ppmlhdfe版本的时候报“existing lftools.mlib is version ‘2.9.2 06apr2017’; need to recompile for ‘2.37.0 16aug2019'”，这个该怎么recompile呢？求指教先谢谢了
