Could not install Hex because Mix could not download metadata at https://repo.hex.pm/installs/hex-1.x.csv.
Alternatively, you can compile and install Hex directly with this command:
mix archive.install github hexpm/hex branch latestThe command '/bin/sh -c mix do local.hex --force, local.rebar --force' returned a non-zero code: 1

Hello ! I have a question, I followed the steps in Manual Installation from the doc (https://docs.blockscout.com/for-developers/manual-deployment), but when I arrived at the step 4 mix do deps.get, local.rebar --force, deps.compile I get the following error :
** (CompileError) config/config.exs:66: undefined function config_env/0
(stdlib 3.14) lists.erl:1358: :lists.mapfoldl/3
(elixir 1.10.3) expanding macro: Kernel.to_string/1
config/config.exs:66: (file)
(elixir 1.10.3) expanding macro: Config.import_config/1
config/config.exs:66: (file)I have installed all requirements listed in the doc and here is the Elixir version I use :
$ mix -v
Erlang/OTP 23 [erts-11.1.8] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1]
Mix 1.10.3 (compiled with Erlang/OTP 22)Does anyone have an idea about what I did wrong ?
Thank you
