【问题描述】：
我对 ERLC_OPTS 进行了修改，至少我是这么认为的。 不得不清理我的 erlang.mk 并且没有保存它。
在哪里添加警告 ok 标志？

我尝试将-W0 添加到此：
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} ->
但我仍然收到该错误。
