我找不到可能导致第137行或更高版本错误的代码的任何部分？

Answer 1

第136行的代码中有反斜杠：

throw new Exception("Local file '" . $file . "' does not exist");\
                                                                 ^

Answer 2

在这里，你有一个不必要的反斜杠，

throw new Exception("Local file '" . $file . "' does not exist");\

注意：请使用IDE检测此类微不足道的错误。

Answer 3

这条线的末尾是否有反斜杠？

Exception("Local file '" . $file . "' does not exist");\
