Python 3.5无法读取zipfile

问题描述

我正在使用https://github.com/overhangio/openedx-scorm-xblock和openx的杜松版本。在我尝试上传zip文件时配置了所有S3存储桶后，出现此错误

Internal Server Error: /xblock/block-v1:EDX+E101+2020_E+type@scorm+block@57eff9f97a5c41248eea66bf9e4c92f8/handler/studio_submit

实际上导致此错误的代码块是 https://github.com/overhangio/openedx-scorm-xblock/blob/master/openedxscorm/scormxblock.py#L189

        with zipfile.ZipFile(package_file,"r") as scorm_zipfile:
            for zipinfo in scorm_zipfile.infolist():
                # Do not unzip folders,only files. In Python 3.6 we will have access to
                # the is_dir() method to verify whether a ZipInfo object points to a
                # directory.
                # https://docs.python.org/3.6/library/zipfile.html#zipfile.ZipInfo.is_dir
                if not zipinfo.filename.endswith("/"):
                    default_storage.save(
                        os.path.join(self.extract_folder_path,zipinfo.filename),scorm_zipfile.open(zipinfo.filename),)

我已经尝试了很多方法，但仍然找不到该问题的实际解决方案。我在这里做错的任何建议。

在AWS s3存储桶中，当我尝试使用此scorm xblock上传zip文件时，也会创建一些zip文件
