I did several react projects before but it is the first time I encountered this problem.
After I ran
npx create-react-app myapp
cd myapp
I created a react project, then I ran
npm start
It looks very fine:
However, the project did not show in the browser, when I go to the localhost:3000 it reminds me "This site can’t be reached":
I tried to change the port but no matter what I do, this situation still lasts. The environment is good, the computer is good, the nodejs is good, anyone has encountered this kind of situation before can give me some advice? Thanks!
