I’m reading the ebook Programming Phoenix 1.4 and in the page 268 when I try to execute the iex it complains for this: ** (RuntimeError) environment variable WOLFRAM_APP_ID is missing. (stdlib) erl_eval.erl:680: :erl_eval.do_apply/6 (stdlib) erl_eval.erl:449: :erl_eval.expr/5 (stdlib) …

As I said, I’d not hardcode it there for several reasons, but use a .env or .envrc for the project (not comitted into source control) and source it before working with the project. direnv is a nice tool for such setups. It will automatically “execute” .envrc files when entering a directory, if that…

You need to set an environment variable that’s visible to your BEAM process. How to do that depends on your operating system. If you use linux/mac with a sh compatible shell, then it’s export, for fish and windows it’s set.

Yeah just see my edited post. It’s export then (under the assumption that you use bash or zsh, which both are the default shells in Mac, depending on the version, but as I’m not a Mac user by myself I have no clue when the change happened)

Hi, echo $SHELL Mojave: /bin/bash → .bash_profile Catalina: /bin/zsh → .zprofile https://forum.elixirforum.com/t/programming-phoenix-could-not-fetch-application-environment-wolfram/26584

I’d not hardcode it into any of those…

I use zsh. So I put in the ~/.zshrc file?

Just for help if someone stopped like me in this part of the book, I’ll share what I do for run correctly. I create inside the config folder a .env file and then add: export WOLFRAM_APP_ID="XXXXXX-XXXXXXXXXX" then after I run on terminal: source config/.env And then I try iex -S mix: iex(1)> I…

[image] romenigld: Then I add in the .gitignore file: # Ignore .env files /.env This will only ignore .env from the repositories root. If you want to exclude config/.env, then you have to do /config/.env, assuming that git-root and project root are the same. Other than that, the flow seems…

Yes, you are correct. Thank’s again @NobbZ !
