python3安装pandas库出现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/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)

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：
