what is the reason ?
回答1:
Chances are that either:
A. Your Windows Hosts file does not have this entry:
127.0.0.1 localhost
B. Or this entry is 1st (comes before the above), and Apache is Listening on IPv4 only:
::1 localhost
In the second case, just remove or comment out the entry.
Hosts file path:
C:Windows\system32\drivers\etc\hosts
You'll need to edit Hosts file via 'Run as admin' on Notepad.
