Answer 1

Although saving the shell file locally and then running it can solve this problem, but you'll meet it again when you do something similar(e.g. install oh-my-zsh, vim-plug, etc.)

At last, I find the 3rd item of this answer(https://stackoverflow.com/a/61787208/5458745) works best for me, as it can also solve the problem I meet when installing other tools using curl. However instead of changing the DNS, I add 8.8.8.8 to my original DNS server list, which works fine for me.

Change your DNS server to 8.8.8.8 (This is worked for me)
