You forgot the return type in your method definition. Therefore the body is not well parsed.
您忘记了方法定义中的返回类型。因此身体没有被很好地解析。
For example:
例如：
def scaleMap(file: File, key: String): Map[String Int] = { ... }
If you don't know the correct return type immediately, you can just ignore the returnpart of the method definition. The return type will then be inferred by the compiler.
如果您不立即知道正确的返回类型，您可以忽略return方法定义的部分。然后编译器会推断返回类型。
def scaleMap(file: File, key: String) = { ... }
