python之python3安装pandas插件出现Could not import the lzma module.
1、错误如下：
-
>>> import pandas
-
/usr/local/python3/
lib/python3
.7/site-packages/pandas/compat/__init__.py:
85: UserWarning: Could
not import the lzma
module. Your installed Python
is incomplete. Attempting
to use lzma compression will result
in a RuntimeError.
-
warnings.warn(msg)
-
/usr/local/python3/

如下图所示：
2、安装lzma模块使用：python -m pip install backports.lzma，如下图所示：
3、然后找到/usr/local/python3/lib/python3.7目录（机器不同，目录也有所不同，可以通过which命令来查找当前运行python是使用的那个目录的），然后编辑lzma.py，将：
-
from _lzma
import *
-
from _lzma
import _encode_filter_properties, _decode_filter_properties
如下图所示：
更改为：
-
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
如下图所示：
4、保存退出，然后在次import，如下图所示：
