我正在使用dynamic_compile动态创建logger。它通过钢筋开始时告诉错误，但正常启动时更正。请帮忙看看。这是我的little demo project on github。
以下是我的步骤：
步骤报告错误：
~/rebar_test > rebar compile generate
~/rebar_test > ./rel/server/bin/server console
然后得到错误：
=CRASH REPORT==== 4-Dec-2012::20:37:19 ===

正确的步骤：

它说的是正确的：

答案 0 :(得分：1)
这引起了我的注意：
"Error compiling logger (~p): ~p~n",
[error,undef]],
我认为您需要将compiler添加到rel/reltool.config，否则您将无法在运行时编译模块。
