Python 3.x 如何解决；没有名为“U bz2”的模块；错误？

我试图在Python 3.6中使用

s3fs

，使用Debian 3.16.51-3

导入s3fs时：

import s3fs

...
from _bz2 import BZ2Compressor, BZ2Decompressor

ModuleNotFoundError: No module named '_bz2'

好的，我试着更新/安装

libbz2 dev

，正如SO中的其他问题所述

sudo apt-get install libbz2-dev

尝试使用

--修复丢失的
，但出现相同错误。显然，这些文件无法下载（？）

我应该如何处理这个问题？提前感谢。
您解决了这个问题吗？你能分享一下吗？
