尝试使用Mix进行安装，（Mix）无法访问url错误

Question

I am trying to install elixir packages and whenever I use mix command, I get this kind of message,

mix archive.install https://github.com/phoenixframework/phoenix/releases/download/v1.0.0/phoenix_new-1.0.0.ez
Are you sure you want to install archive https://github.com/phoenixframework/phoenix/releases/download/v1.0.0/phoenix_new-1.0.0.ez? [Yn] y
** (Mix) Could not access url https://github.com/phoenixframework/phoenix/releases/download/v1.0.0/phoenix_new-1.0.0.ez, error: {:failed_connect, [{:to_address, {'github.com', 443}}, {:inet, [:inet], :nxdomain}]}

How do I avoid this?

Answer 1

I needed to ensure than ~/.mix/archives directory has write permission.

sudo chmod a+rw ~/.mix/archives/ solved the problem.
