我尝试添加-W0这样：

Write(["ERLANG_ARCH = ", rebar_utils:wordsize(), "\nexport ERLANG_ARCH\n"]), 
     fun() -> 
       Write("ERLC_OPTS = +debug_info -W0\nexport ERLC_OPTS\n"), 
       case lists:keyfind(erl_opts, 1, Conf) of 
         false -> ok; 
         {_, ErlOpts} ->

但我仍然得到这个错误。

答

您可以尝试通过设置ERLC_OPTS这样筛选出的默认选项Erlang.mk用来编译： ERLC_OPTS := $(filter-out -Werror,$(ERLC_OPTS)) 按Erlang.mk user guide
