If we run command in Remote mode, it well report 'ERR spawnSync global ENOENT: Error: spawnSync global ENOENT'.
It can be fixed by given exe path like
{
"gnuGlobal.gtagsExecutable": "/usr/local/bin/gtags",
"gnuGlobal.globalExecutable": "/usr/local/bin/global"
}
Not sure why this happened, but it could be enhanced.
