Could not find Hex, which is needed to build dependency :cowboy
Shall I install Hex? [Yn] y

** (Mix) httpc request failed with: {:failed_connect, [{:to_address, {'s3.amazonaws.com', 443}}, {:inet, [:inet], :closed}]}

Could not install Hex because Mix could not download metadata at https://s3.amazonaws.com/s3.hex.pm/installs/hex-1.x.csv.signed.

Can you please include Elixir and Erlang version? Just run iex. Also, let us know if the problem still persists and/or if you are running behind a proxy.

@josevalim no proxy, please see the below image:

That's weird. For now, please try downloading directly: http://s3.amazonaws.com/s3.hex.pm/installs/1.1.0/hex-0.9.0.ez

And then run: mix local.install path/to/downloaded/hex-0.9.0.ez. Please make sure you are safely downloading the file in your browser.

enetunreach suggests a network issue on your end. Can you reach https://s3.amazonaws.com/s3.hex.pm/installs/hex-1.x.csv.signed in your browser?

[psychoss]

@ ericmj can reach http://s3.amazonaws.com/s3.hex.pm/installs/hex-1.x.csv.signed

@josevalim i have installed the hex-0.9.0.ez. but still have trouble to install the modules, is possible download them directly like "http://s3.amazonaws.com/s3.hex.pm/installs/1.1.0/hex-0.9.0.ez"? i'm from china , at here to reach "s3.amonzon.com" is always a problem.

[josevalim]

You can try using the southeast-asia mirror. After you install Hex, run this:

mix hex.config cdn_url https://s3-ap-southeast-1.amazonaws.com/s3-asia.hex.pm

Let me know how it goes!

[psychoss]

@josevalim thanks your very quick response, it was now working fine

[zsherman]

@josevalim thanks, also worked for me.

That should be mix archive.install path/to/downloaded/hex-0.9.0.ez.
