我正在尝试下载SRTM1图像。当我运行代码时，出现此错误：
make: *** [spool/N41/N41E012.hgt.gz] Error 60
Makefile:17: recipe for target 'spool/N41/N41E012.hgt.gz' failed
make: Leaving directory 'C:/Users/visioterra/AppData/Local/bopen/elevation/Cache/SRTM1'
当我尝试使用SRTM3时，我得到了：
make: Nothing to be done for 'download'.
make: Leaving directory 'C:/Users/visioterra/AppData/Local/bopen/elevation/Cache/SRTM3'
make: Entering directory 'C:/Users/visioterra/AppData/Local/bope/elevation/Cache/SRTM3'
gdalbuildvrt -q -overwrite SRTM3.vrt
ERROR 1: No input dataset specified.
Usage: gdalbuildvrt [-tileindex field_name]
make: *** [SRTM3.vrt] Error 1
我使用模块标高。 我怎样才能解决这个问题？ 谢谢
