The problem is solved. It is the problem of network.

If you’re in mainland China, you can target to the mirror servers

For instance, downloading from BFSU server would be blazingly fast by setting the environment variable:

julia> ENV["JULIA_PKG_SERVER"] = "https://mirrors.bfsu.edu.cn/julia"

More information can be found in Julia PkgServer 镜像服务及镜像站索引 - 库的安装及使用 - Julia中文社区
