python import pandas时提示Could not import the lzma module

# 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
