您好，我是小白，和您请教一下哦。如果您有空QQ回复的话，非常感谢！
我在第一步输入完安装homebrew的命令后，终端报错
wangneddeMBP:~ ned$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
curl: (28) Operation timed out after 300128 milliseconds with 0 out of 0 bytes received
不知道怎么回事，而且安装第二步，e2fsprogs，也报错。
装homebrew的时候，报错还会显示这样，
The default interactive shell is now zsh.
To update your account to use zsh, please run `chsh -s /bin/zsh`.
