Erlang：Mnesia在使用钢筋释放时无法创建模式 [英] Erlang: Mnesia can not create schema while release with rebar

问题描述

当我在启动时调用mnesia：create_schema时，程序崩溃。
如果我在ebin中运行我的程序，而不释放它，它可以找到。
错误日志如下：

When I call mnesia:create_schema on startup, the program crashes. If I run my program in ebin without releasing it, it works find. The error log as follows:
