我该如何解决这个创建反应应用程序初始化错误

Question

Hello all I've been having issue creating a react app, keeps showing me that on screenshot above. Tried so many guides found here, not working. Cleared cache and even uninstalled and reinstalled node still not working.

Please what could be the cause

Answer 1

Based on

tunneling socket could not be established, ECONNREFUSED 127.0.0.1:80

you have configured Yarn to use a proxy or tunnel that should be running on port 80 on your local machine, but isn't.

See yarn config list for relevant options and yarn config delete to get rid of the configuration entry that's causing trouble.
