Looks like a really old version of Phoenix. Can you try downgrading Elixir to 1.11?

I am running elixir-1.12.1 and erlang 24

Yeah, that’s what I inferred from your error message. Try upgrading Phoenix or downgrading Elixir - there seem to have been some changes to EEx in 1.12.

Thanks downgrading elixir-1.12.1 to elixir-1.11.1 enables the phoenix framework compile
@chrismccord and @josevalim please check on this

You are using a very outdated version of phoenix. 1.2.5 has been released July 27th 2017. Thats almost exactly 4 years now. Since then there has been 1.3.x, 1.4.x and 1.5.x.

I do not think, that there will be any compatibility fixes to a such old version of phoenix.

Update phoenix or downgrade elixir. Personally I’d prefer updating phoenix.

users-MacBook-Pro:Downloads $ cat ~/.mix/archives/

But When upgrade my elixir from elixir-1.11.1 to elixir-1.12.1 its failing

Your application uses phoenix 1.2.5:

Check its constraints and lockfiles.
