Port conflict in 8080 and program won't start, it is better to config other ports

[HubMatthewTan]

Totally new for this axios, so I did npm install / and npm run dev as instructed,
when I run http://localhost:8080/, the firefox starts, but the browser gives me some error message from apache as below,
[Welcome, That's right! If you are seeing this it means that the web server installed at this site is working properly, but has not yet been configured. ]
Since generally we have lost of projects require Apache port 8080, so I change the src\config\index.js port to 8081. and It is OK now!
