问题
I have a running web application on my local machine. To get access to it I can use localhost:8080. But when I try to use http://127.0.0.1:8080 address my browser says: The 127.0.0.1 page isn’t working.
Ping to it does not work as well:
ping 127.0.0.1:8080
ping: cannot resolve 127.0.0.1:8080: Unknown host
How can I fix it?
回答1:
Open a terminal window and type this line:
sudo open -a TextEdit /etc/hosts
You will be prompt to type in your admin password and your host file will open in TextEdit. Add this line in your host file :
127.0.0.1 localhost
Save the file and close. That's it.
