'dfx start' commond return http 503, 'sudo dfx start' command success

Hello,I installed ‘dfx’ with command ‘sh -ci “$(curl -fsSL https://smartcontracts.org/install.sh)”’,
but now I cannt start my program without sudo, what’s wrong with my dfx command

In order to fix this problem, the system has been restarted and reinstalled,but it still doesnt work

If that can help, on OSX I was in need of sudo too. This is how I fixed it.

thanks for your suggestion,it doesnot work

In addition, I also often have to do the same on the .dfx folder in the project.

Sorry no other idea.
