我为漫画网站写了一个简单的网络抓取工具。我在Ubuntu（Linux ubuntu 4.18.0-16-generic #17~18.04.1-Ubuntu）上运行它，但是当我执行脚本（权限设置为chmod ug+x）时，导入的系统库不断出现一系列错误以及令人困惑的语法错误：
import-im6.q16: not authorized `time' @ error/constitute.c/WriteImage/1037.
import-im6.q16: not authorized `os' @ error/constitute.c/WriteImage/1037.
import-im6.q16: not authorized `sys' @ error/constitute.c/WriteImage/1037.
import-im6.q16: not authorized `re' @ error/constitute.c/WriteImage/1037.
import-im6.q16: not authorized `requests' @ error/constitute.c/WriteImage/1037.

./poorlywrittenscraper.py: line 15: DEFAULT_DIR_NAME: command not found
./poorlywrittenscraper.py: line 16: syntax error near unexpected token `('
./poorlywrittenscraper.py: line 16: `COMICS_DIRECTORY = os.path.join(os.getcwd(), DEFAULT_DIR_NAME)'
有趣的是，当我通过python3它运行相同的脚本时，它会启动，创建文件夹，获取图像，但是...不会保存它们。O
知道我在这里缺少什么或如何解决这个问题吗？
这是脚本的完整代码：
