python - ParsePy：如何删除文件

Question

我正在使用 ParsePy ( https://github.com/milesrichardson/ParsePy )，现在我遇到了文件删除问题。

from parse_rest.datatypes import Object, File

class GameScore(Object):
    pass

with open('/path/to/screenshot.png', 'rb') as fh:
    rawdata = fh.read()

screenshotFile = File('arbitraryNameOfFile', rawdata, 'image/png')
screenshotFile.save()

gs = GameScore.Query.get(objectId='xxxxxxx')
gs.screenshot = screenshotFile
gs.save()

#
# In another function
#
class GameScore(Object):
    pass

gs = GameScore.Query.get(objectId='xxxxxxx')
gs.screenshot.delete()

# Error: No JSON object could be decoded

有什么建议吗？提前致谢。洛里斯
