在centos安装xz-devel，然后重新编译一下

yum install xz-devel

./configure --enable-optimizations

安装backports.lzma包

pip install backports.lzma

修改python文件

# /usr/local/python3.x/lib/lzma.py

原：

from _lzma import *

from _lzma import _encode_filter_properties, _decode_filter_properties

改：

 try:

     from _lzma import *

     from _lzma import _encode_filter_properties, _decode_filter_properties

 except ImportError:

     from backports.lzma import *

     from backports.lzma import _encode_filter_properties, _decode_filter_properties
