Then something super weird is going on, likely permission issues. We can’t help much if basic system expectations don’t hold up. She should troubleshoot and pursue. What’s even weirder is that just some file in the homedir made the whole thing work.
But can’t fault her really, especially if something you thought trivial wasted you a lot of time you’ll just be happy that you found a solution that worked eventually.
Just ran into this issue after brew decided to update asdf (while I was installing another package). mix and elixir commands were both available and working in other projects, but even though I had a .tool-versions file, I was getting command not found: mix, despite asdf install reporting I had elixir installed.
The solution was just to add the asdf PATH to my ~/.zshrc as outlined in the asdf install page. It seems updating through brew won’t take care of this for you (even if it was an auto-update).
Hopefully this helps someone else!
Literally couldn’t figure out this issue over the last 3 hours and you post this 2 hours ago lol, thank you!
For anyone too lazy to open the link, remove all lines related to asdf from your .zshrc and add the following line:
export PATH="${ASDF_DATA_DIR:-$HOME/.asdf}/shims:$PATH"
Then, for good measure, run asdf reshim and close all terminal windows before trying to run mix ... again.
