反应项目编译成功但不显示在浏览器上

Question

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!

Answer 1

This is happening because of the env variable HOST .

To fix that you need to add HOST="localhost" to your ~.bash_profile file, and then reload the env variables using source ~/.bash_profile . (don't forget to restart your server)

This should fix your problem.
