                                                   ^
SyntaxError: invalid syntax

二、解决

1.可以看到报错的重要信息为

File "/usr/local/lib/python3.5/dist-packages/s3transfer/__init__.py", line 592
    range_param = f'bytes={start_range}-{end_range}'
                                                   ^
SyntaxError: invalid syntax

2.查看版本

pip3  show s3transfer
# 报错版本： 0.5.2
# 正常版本： 0.5.0

3.调整版本

pip3 uninstall s3transfer
pip3 install s3transfer==0.5.0

至此，问题解决
