TP5 thinkphp5 report serialization of'closure'is not allowed

I encountered this problem when writing the query today ：

reason ： If you have a closure in your global domain, an error will be reported as “ Serialization of closures is not allowed ” , I found what I wrote earlier where() Method uses closures , Query results used cache() Method （cache The method is to serialize the data into a file ）, Remove cache This error will not be reported after the method , Or not where The closure method will not report this error , This error will not be reported after any modification of one of them .
