Elixir formula doesn't find Erlang on Yosemite

[thillerson]

After doing a clean install of Erlang (OTP 17), and a clean install of Elixir (14.1) iex doesn't run, but fails with:

/usr/local/Cellar/elixir/0.14.1/bin/elixir: line 97: exec: erl: not found

Starting erl from the command line works fine.

I am also having the issue mentioned above, if that helps.

This is almost certainly due to the 10.10 PATH thing, so I don't think Homebrew can do anything to fix it. Hopefully it will be fixed in the next 10.10 preview.

looks like it wasn't fixed... Do we have a solution yet? Still happens with release version of yosemite.. :/

Please read the troubleshooting guide and open a new issue with all requested diagnostics, thanks!

I'm getting this same issue, and it seems to be happening here in the code. I'm not a Bash pro but the check for if [ -f $SCRIPT_PATH/../releases/RELEASES is failing so I assume the second check isn't even bothered with so ERL_PATH is set to erl. When i change it to ERL_PATH=/usr/local/bin/erl the problem goes away. I'm sure it's something with my environment, and not the script, but this could be use as a temporary hack. I'm on Yosemite, and homebrew 0.9.5, using iTerm2.

if [ -z "$ERL_PATH" ]; then
    if [ -f "$SCRIPT_PATH/../releases/RELEASES" ] && [ -f "$SCRIPT_PATH/erl" ]; then
      ERL_PATH="$SCRIPT_PATH"/erl
    else
      ERL_PATH=erl
   fi
 fi
