好怪！不管用哪種
我的ＩＰ都會顯示 ::1
怎麼會這樣？

我看xampp的ＬＯＧ寫

Starting ProFTPD...
Exit code: 8
Stdout:
Checking syntax of configuration file
proftpd config test fails, aborting
Stderr:
xxx-2.local proftpd[1549]: warning: unable to determine IP address of 'xxx-2.local'
xxx-2.local proftpd[1549]: error: no valid servers configured
xxx-2.local proftpd[1549]: Fatal: error processing configuration file '/Applications/XAMPP/xamppfiles/etc/proftpd.conf'

整個壞掉了
我也不知道是什麼原因？根本沒有動到呀
