Did you use any undefined module? Please check if there is any typo in your source code.

信号路径错

我们自己翻译为：“交叉引用错误”
我以前也经常遇到这个错误，
一般很容易找到错误原因，
我的记忆中好像在调用Class的Task或Function时容易出现，
好像常常是参数引用的问题。
我想大概意思是：你说调用的Task或Function参数不对或是在这里根本无法调用。
如果可以最好给出具体错误的代码，以便分析。
对此记忆很模糊，仅供参考

在用ｆｕｎｃｔｉｏｎ或者ｔａｓｋ的时候，ｖｃｓ没有找到对它的定义或申明，应该把它ｉｎｃｌｕｄｅ进来

急求解答啊！
