cap ado uninstall moresyntax
net install moresyntax, from("https://github.com/sergiocorreia/moresyntax/raw/master/src/")

cap ado uninstall ftools
net install ftools, from("https://github.com/sergiocorreia/ftools/raw/master/src/")

if (c(version)<13) cap ado uninstall boottest
if (c(version)<13) ssc install boottest

不好意思，我尝试了以上命令，net install moresyntax这一行命令显示报错，称这个网址找不到，我也尝试了ssc install moresyntax也失败了
