我正在使用avro4s
https://github.com/sksamuel/avro4s
我写了这段代码
implicit val schema = AvroSchema[SalesRecord]
val output = AvroOutputStream[SalesRecord](new File(outputLocation))
output.write(salesList)
output.flush
output.close
但我得到一个编译时错误
could not find implicit value for parameter builder: shapeless.Lazy[....]
Not enough arguments for method apply
