Mix deps.get error - (FunctionClauseError) no function clause matching in String.to_charlist/1

Very sorry for misleading.
I’m not use asdf or other version manager. 1.6.4 elixir is my MBP from company and 1.6.5 is home MBP.
Sorry…
Now I’m sure I use the 0.18.1 version of hex.
Is there some setting (httpc or other) bind up with project not branch or computer? Because as I mentioned before: same computer same environment phoenix project one deps.get work another can’t. And in the error project, I checkout branch to master it still error. I think this will be the only entry point I fix this.
